The Rich Roll Podcast - Optimize Your Brain: Team Sherzai On Fighting Cognitive Decline With Nutrition & Lifestyle

Episode Date: March 22, 2021

Alzheimer’s isn’t a genetic inevitability. A diagnosis need not come with a death sentence. In fact, many things can be done to prevent & ameliorate cognitive decline. So let’s talk about it. To...day we dive deep into brain health. More specifically, how you can maintain and optimize your cognitive functionality and take an insurance policy out against succumbing to neurodegenerative diseases like Alzheimer’s. Our guides for this exploration are husband and wife neurology duo Drs. Dean and Ayesha Sherzai, returning for a second turn on the podcast (if you missed it, RRP #330 is a must-listen). Affectionately known as Team Sherzai, Ayesha & Dean are the highly credentialed co-directors of the Brain Health and Alzheimer’s Prevention Program at Loma Linda University Medical Center, where they study all things brain health, with a particular focus on lifestyle interventions to prevent cognitive decline and neurodegeneration. Because Alzheimer’s currently afflicts over 40 million people worldwide, I’m willing to bet most of you are directly or indirectly impacted by this affliction. The bad news is that there is currently no cure for Alzheimer’s. And incidence is predicted to triple by 2050. What most don’t realize, however, is that 90% of Alzheimer’s cases can be prevented. In fact, through simple diet and lifestyle changes, the Sherzai’s have experienced remarkable success in both preventing and significantly reversing the symptoms of Alzheimer’s, dementia and cognitive decline in many of their patients, adding vibrant years to their lives. The science behind dementia, the non-interventional means to optimize brain health, and the many strategies to prevent cognitive decline are robustly explored in The Alzheimer’s Solution (the focus of our first podcast) and the Sherzai’s latest book, The 30-Day Alzheimer’s Solution. The solution might surprise you. It’s not due to a breakthrough in surgical procedures. It’s not the result of new pharmaceutical trials. It’s about food. Exercise. Restorative sleep. Community. And maintaining a life of purpose.

Starting point is 00:00:00 When you look at the factors that stand out that contribute to better brain health, it's nutrition, it's exercise, it's stress, it's sleep, and the one that we added is cognitive activity. So when we wrote the first book, we came with this acronym, NEURO, N-E-U-R-O, you know, N is for nutrition, E is for exercise, U is for unwind, which is stress management, not just getting rid of stress, but increasing good stress and getting rid of bad stress. And R is for restorative sleep, deep restorative sleep that helps cleanse the brain and has its own function and optimization of cognitive activity. One of the things that actually gets people to the dementia stage fastest is what they did throughout their life as far as cognitive activity and challenge. That's profoundly important. Sleep.
Starting point is 00:00:51 We're talking about restorative sleep where people go through the four phases of sleep four to five times a night deeply. So sleep and investing in sleep is profoundly important. And then there's optimization, which is challenging mental activity. So all of it has to be done and all of them have to be done together. And if it's not just a diet du jour, and if it's lifestyle, and especially if it's lived lifestyle, which is what we're trying to do in communities, we're talking about 90% reduction in Alzheimer's, dementia, stroke, without any biohacking or vitamin du jour or any of that stuff, with regular things you have in your environment.
Starting point is 00:01:30 I am Dr. Dean Sherzai. I'm Dr. Ayesha Sherzai. And together, we are SherzaiMD, and this is The Rich Roll Podcast. The Rich Roll Podcast. Hey everybody, how you guys doing? Welcome to the podcast. My guest today, very exciting, our husband and wife neurology team,
Starting point is 00:02:01 Drs. Dean and Aisha Shirze. Together, this highly credentialed duo, are co-directors of the Alzheimer's Prevention Program at Loma Linda University, where they study all things brain health with a particular focus on lifestyle interventions to prevent cognitive decline and neurodegeneration. Here's the thing, chances are there's somebody in your life who's impacted by Alzheimer's because it's a disease
Starting point is 00:02:29 that is exploding right now, currently afflicting well over 40 million people worldwide with incidents actually predicted to triple by 2050, which is very alarming. And although there currently is no cure, what most people don't realize is that Alzheimer's is not a genetic inevitability. It doesn't need to be a death sentence.
Starting point is 00:02:54 And in fact, 90% of all Alzheimer's cases can be prevented. And so what distinguishes the Scherzes from their colleagues is this unique focus that they have on prevention. And they've had pretty remarkable success, significantly reversing cognitive decline and adding vibrant years to many of their patients' lives. The Scherzes first graced the podcast a couple of years ago, that was episode 330,
Starting point is 00:03:23 to talk about their first book, The Alzheimer's Solution. And today they returned to bring us up to speed on the latest science on brain health, to discuss their new book, The 30-Day Alzheimer's Solution. And of course, to provide you with the information, the tools, the nutrition and the lifestyle prescriptions that you need to optimize your cognitive functionality and hopefully sidestep the neurodegenerative diseases
Starting point is 00:03:52 that begin much earlier in life than most people imagine and ultimately and devastatingly afflict far too many. This one is powerful. It's potentially life-changing and it's all coming up in a few, but first. I owe everything good in my life to sobriety.

Okay, team sure as ice. So you guys are gonna wanna break out a pen and paper because this one is quite dense. It's in depth. It's powerful.
Starting point is 00:08:13 Like I said, it's potentially life altering. It's an amazing conversation that I think is gonna provide you everything you need to know about optimizing brain health, preventing cognitive decline and how to avoid the grip of Alzheimer's. I should also mention that if you enjoy this conversation, then check out their podcast, Brain Health and Beyond,
Starting point is 00:08:33 which is available on all the podcast platforms. Okay, let's get into it. What is it about age or maybe neurology that makes people set in their ways as they get older? It is a weird thing, right? It really is. It becomes more difficult to entertain new ideas. Yeah, I think it varies from person to person, but in my experience, it's just comfort. You know, once you set a path and you're comfortable with it,
Starting point is 00:09:05 your brain doesn't really allow you to change that path. It's like walking on a snow track. It's so deeply set and the walls are so solid that it's difficult for you to actually make a new path again. New grooves, right. And it requires a lot of reflection and judgment and being okay to make mistakes
Starting point is 00:09:24 and the discomfort in being uncomfortable, the comfort in being uncomfortable. Right, right, right. They can help you set new ways, but yeah. I don't know what you want to say about that. It does seem like that becomes much more of a challenge. It does, it does. The whole idea of change is not normal.
Starting point is 00:09:43 I'm talking about chronic change, acute change. We're good at it because an acute change we had to for millions of years, there's a tree, there's a lion, I better make change in my decision-making. I'm not gonna go down this path. Long-term change, we're not designed for that. Our brains are not designed for long-term change. That's a completely different mechanism.
Starting point is 00:10:05 And if we don't address that, I mean, to be honest, I know that it's not biblical, our political stances, everything is around this concept of being okay with change. I always say about 5% of population is future seekers. The other 95% is past protectors. And you have to be past protector in many ways because past protection has worked. Whatever has gotten you here is you depending on the past patterns, right?
Starting point is 00:10:33 But all the change in society, in the world around us is by those 5% or whatever. I'm using arbitrary number that are comfortable. This is weird people. Comfortable with change, with the unknown, the 360 degrees of unknown, you're willing to go there. And yet this house that's comfortable, you're willing to leave it to go to the next place.
Starting point is 00:10:53 That's an unusual concept, which comes with the frontal lobe, but that's why as we get older, we become more set on all the strings that connects us to the past. You want us to sever, sever, sever, sever, sever, to go to a new path that is unknown at a time where I'm already vulnerable.
Starting point is 00:11:10 Yeah. That's too much risk. Yeah, yeah. Is there a genetic piece to that? When you look at that 5%, can you isolate out what it is that distinguishes them neurologically from- You can tell very early. You can tell there's a genetic component
Starting point is 00:11:25 or environmental component. The genetic anxiety is at the core of all this stuff or a term that is like anxiety. We're using anxiety as a word that's as a filler, but it's a little more than that. Our ability to deal with the world around us for the most part at the beginning is genetically, you can see the children, we have two children.
Starting point is 00:11:48 Both of them- Trust me, we're gonna talk about them. Go ahead. But they're very precocious, incredibly, but very- Understatement of the century. Go ahead. Very different though, very different. Alex is what you could see when you were,
Starting point is 00:12:04 I'm not putting him down because this is not a weakness. This is just our proclivities. We can change him. When you put him on the sand, when he was six months old, you saw him do this. He hated sand. Sophie would crawl to the ocean. I mean, right away.
Starting point is 00:12:18 I mean, that's a threat. Why are you not threatened by the very thing you're supposed to be threatened by? No threat. So that threat aversion versus not threat aversion, part of it is intrinsically ingrained in us. Part of it is actually data shows, part of it's actually programmed.
Starting point is 00:12:34 How your mother reacts to anxiety provoking moments, mother, because the mother's there all the time. Whoever you're around the most and how they react, no, how they promote challenging situations and anxiety provoking situation, how they react with it and how they deal with it is the, forget about leadership masters. I got a PhD in, forget about that.
Starting point is 00:12:58 Ends and starts there. Yeah. You create situations that are a little bit anxiety provoking. You fail, nothing. Oh, my parents didn't react badly. You succeed, great. How you react and how those micro environments
Starting point is 00:13:14 of threat aversion, threat response, threat creation and response is the foundation of all leadership. Yeah, I would think from an environmental perspective, or I mean, an evolutionary perspective that, maintaining your membership and good standing with your community is paramount, right? So if that community is welcoming to people
Starting point is 00:13:38 who push the boundaries and try new things, that's one thing. But if that sort of thinking outside the box is gonna alienate you, then there's going to be some pushback, right? There's a disincentive that's butting up against somebody's willingness to entertain new ideas or try new things. Yeah, absolutely.
Starting point is 00:13:59 And the culture that's been set in place that creates an aversion to change. The language, the micro languages, that anything that somebody brings that is a little threatening to the status quo, you have things that are out, this is arrogant. The word arrogant to push away people who have new ideas is universal. It's such a ubiquitous silencing technique.
Starting point is 00:14:24 And when you look at the main reason why people are not willing to change is the fear of being ostracized, like you said. Nobody wants to get out of that comfortable zone because it's really difficult to be alone in your way of life, in your new methodology, in your new habits. And that's the first step that people have to way of life and your new methodology and your new habits.
Starting point is 00:14:45 And that's the first step that people have to challenge themselves to take over. Right, given that though, it's interesting that most environments are not really that permissive when it comes to free thinking and creative expression. Most are pretty regimented around what's okay and what's not, but it would seem like we should be more encouraging to that permissive environment.
Starting point is 00:15:10 And why is that? Why are we not able to kind of make that more the case as opposed to the slim 5% or whatever it is? Yeah. Well, we met in Afghanistan with Taliban around us. Yet that same mentality exists here in the medical community. And by the way, this is me not bashing
Starting point is 00:15:33 the medical community. Be careful. No, no, no. We love the medical, we're part of them. You're not comparing the medical community here to the Taliban. No, no, no. Let's clear that up.
Starting point is 00:15:43 Just their mentality, that's all. No, I'm just kidding. No, but the stagnant comfort with the status quo is the same thing. I mean, the hallways of your limbic system are the same. You might've put it better clothes and better beards. And you know, my beard was shaving a little better here. But if the mentality is I must maintain,
Starting point is 00:16:04 it's not always overt. I must maintain the status. And I don't know even why, because that it makes me uncomfortable. It's the same. Yeah. I mean, in 2002, before we met, two months earlier, I'm at NIH,
Starting point is 00:16:19 Experimental Therapeutics Branch. That's as wonky, as experimental as it gets, speaking with Nobel prize winners. Two months later, I'm in Afghanistan speaking with Taliban leaders. Both places trying to bring change. And I can promise you, the language was much more sophisticated,
Starting point is 00:16:39 but the blockades were the same. Protection of the status quo. That's why, I mean, when we talk about dementia, we talk about stroke, we talk about mental health, even now that the repetition of the same patterns over and over again, I'm now some other studies are starting with clinical trial and with a hundred people, 50 people, six months,
Starting point is 00:16:57 we're done, we know what works. We're whole food plant-based. Right. But reality is if you go 20% better than what the standard American diet is, you will do 20% better in your healthcare. What does that mean? That means in Alzheimer's,
Starting point is 00:17:14 that's $80 billion saved per year. Right, right. Well, it's been a couple of years since you guys have been on the show. And in that intervening period of time, have you found that the sort of conventional medical community has been a little bit more embracing of you than in years past,
Starting point is 00:17:34 given the success that you're having and the results that you're seeing in your patients or what does that look like right now? They have, we are seeing a lot of open-mindedness to the idea that lifestyle works, that it's important, that it should be a part and parcel of the bigger conversation about health and wellness in general.
Starting point is 00:17:55 And everywhere we go to the conferences, medical conferences, and it was always focused on molecularly research, which is very important. But lately there's been a lot of conversation about the importance of community-based research and lifestyle and addressing our environments, which is wonderful. So yes, they are very welcoming and I'm very encouraged to see that. Still contrived, still not as intensive as it needs to be. I think there's a lot of need for improvement,
Starting point is 00:18:28 for better communication. And that's what Dean and I have been working on, reaching out into the communities to see what fits there, because the cookie cutter model of something that fits, say for example, 50 to 60 year old Bostonian white men wouldn't really be applicable in San Bernardino in a Hispanic community, for example. So finding out specifically what is applicable,
Starting point is 00:18:52 what works long-term and what people can accept is the part that we are working on. Right. So many things I wanna get into with you guys. First of all, thank you for coming. It's our pleasure. Thank you for having us. It's really get into with you guys. First of all, thank you for coming. It's our pleasure. Thank you for having us. It's really nice to see you guys.
Starting point is 00:19:07 I'm delighted that you're here today. We're gonna pick things up where we last left off with them a couple of years ago, but I gotta get this out of the way first. I gotta talk about your kids because I'm obsessed with how accomplished these two young people are. You've got your son, Alex, is he 15 now? He's 15, yes. He's in college.
Starting point is 00:19:31 Yes. Right. Sophia is, how old is she? 13. 13. Yes. They've written this book, "'Walk Like an Elephant," which is all about protecting wild elephants from poachers. But just to give listeners or viewers
Starting point is 00:19:45 a sense of what's going on here, Alex mastered calculus at eight, correct? That's right. He wrote this book, he completed high school at 10 with a SAT in the 90th percentile. He's the youngest person to have his research abstract be accepted to an international neuroscience conference. True or false?
Starting point is 00:20:07 Yes, true. Okay, he's a pianist, he's a composer. Meanwhile, Sophia was reading fluently at two and a half. She was, yes. Good Lord. And she co-wrote this book when she was eight. She finished high school when she was 10 with a 90th percentile on the PSAT
Starting point is 00:20:26 and has been a speaker at Science LA in 2017 and 2018. All right, so I don't even know where to begin with this, but as neurologists, you're doing something right here. Like how do you account for this? There's a nurture aspect to this, there's a nature aspect to this. I mean, this is extraordinary. I've never heard of two young people in the same house
Starting point is 00:20:50 excelling at such a level in terms of like their brain health, which is what you guys are all about. So help me understand what's going on. And congratulations, by the way. Oh, thank you so much. No, not at all. Oh, that's very kind of you. I'm feeling very insecure as a parent. No, no, no, not at all. The most important thing is, so I'm sorry if the mother should,
Starting point is 00:21:12 she's actually the reason. No, no, not at all. I think it's teamwork. And I think I just want to say something first. And I, you know, there are a lot of times, it's tough to talk about your children and because it's a work in progress. I always tell my friends, ask me in five years
Starting point is 00:21:27 after they go through their teenage years, but I'm just really proud of their accomplishments. And I don't really consider them as mine. They're just these amazing individuals. And I, we feel like we're their guardians and it's been such an amazing process of self correction and reflection. Earlier, Dean was talking about the importance
Starting point is 00:21:47 of anxiety management during childhood. And no matter how many books you read, no matter what scientific papers you read about and how much you know about how the brain works, when it comes to the application of that knowledge, it's a whole new experience. So it's been a growing period for both of us as well while raising these kids.
Starting point is 00:22:10 No, it's a challenge even now. I mean, expectation, so I say sometimes bombastically that the secret to life is management of expectations, but it's micro expectations, minute by minute expectations from, so early on, it wasn't about them following a curriculum, throwing things in front of them. I mean, the shower curtain was the periodic table
Starting point is 00:22:31 and the wall was the map. And so throwing in front of them and seeing what, which proclivities, and then you build around that and build around that small micro, almost like, you know, Skinner's reinforcements. So you saw a little bit of improvement here or attention, and then you moved it along, more moved along. And then before you knew it, I mean, Alex had,
Starting point is 00:22:53 so one of his proclivities early on was, and it doesn't matter what it is, if you find that little nidus that just grows and was memorizing capitals of, so by two and a half, three, Right. He had memorized, and we have video, memorized all of the world's capitals of, so by two and a half, three. Right. He had memorized, and we have video, memorized all of the world's capitals,
Starting point is 00:23:08 all the state's capitals. And I couldn't even, I am terrible. Yeah, okay. Antananarivo. Antananarivo, remember? Yeah, yeah. So, I mean, you would show him a shape and he would say, oh, this is this country in the cap. I remember when we used to go to a restaurant
Starting point is 00:23:22 and they would bring some chips and salsa or some bread. And he would take a chip and bite it off. And then he would look at it. Oh, Molly. I was like, who's Molly, honey? No, country Molly. And he would just take another bite. Like, look, Kenya.
Starting point is 00:23:38 So he was just like a visual learner. It was so amazing to see him absorb all this information. Again, work in progress. We have the teenage periods where they get, you know, the frontal lobe and we tell them, there it is, there's the emotional brain taking over. But reality is, I think, and it's not because of us, or I mean, the potential of human brain,
Starting point is 00:23:59 I mean, 87 billion neurons. We're talking about each of them making a couple of connections or 15,000 to 30,000 connections, one quadrillion connections, one times 10 to the 50th power. Now, the answer to that is not sit down and memorize. That's the worst thing. You narrow the funnel to a point.
Starting point is 00:24:21 Yeah, you push through that funnel. They will get through, they'll get to the college, maybe even Ivy league, but you've just killed all the 360 degrees of potential and creativity. The answer I think, and we might be wrong, is throwing and systematically seeing where the proclivities and reinforcing.
Starting point is 00:24:39 Proclivities takes a lot of work, but the human brain is absolutely remarkable, which speaks to both ends of the spectrum. From aging brain, which we are actually under, we keep talking about avoiding disease. I'm talking about profound growth of cognitive capacity, well into our 60s, 70s, 80s and beyond. And then for children, the brain is growing so fast.
Starting point is 00:25:07 And the best argument on internet is, oh, are they choline deficient because they're not getting, you know, eggs or something? Are you kidding? Right. So did you guys homeschool your kids or how did you navigate the educational system to prevent them from, you know,
Starting point is 00:25:24 the best parts of them getting hammered out? It was challenging, especially because when I was, when I had Sophie, I had just started my residency program. So it was a very intense time. And we explored different schools, different systems. They did very well initially for a few years in the Montessori system, which was kind of aligned with what we wanted them to be exposed to, you know, thrown in an environment to see what works for them and have the option of absorbing oneself
Starting point is 00:25:57 in one subject at a time, rather than, you know, having a couple of hours each and every subject every day. Just the mind doesn't really work that way. And after a while, we saw that the speed with which they were learning was probably inhibiting them to be creative in that environment.
Starting point is 00:26:16 And there were a couple of stories where the kids didn't feel very comfortable expressing their creativity and their knowledge because of the peer pressure, because of just the general setting. And when we realized that, I think Dean is fearless. He's way more fearless than I am. He said, nope, I think we should withdraw right now and we should create an environment for them at home. And we were traveling quite a bit too. I actually got into a fellowship program at Columbia University. So I was going back and forth between home and New York.
Starting point is 00:26:45 And we wanted the kids to have a constant creative environment. And so we homeschooled them. And my mother helped. His mother helped. We had a really good system going. And before we knew it, the kids were, and this is not just bragging about them. The kids were, and this is not just bragging about them. It was just an amazing example of how the brain works,
Starting point is 00:27:12 where they would just go deep into a subject and progress so much into it that a point came where we weren't able to help them with their homework anymore. For example, Alex went to algebra and then went to calculus. Sophie was so far in linguistics, we were just amazed. And so we quickly understood that the conventional model doesn't help at all.
Starting point is 00:27:34 And they took their SATs and they did very, very well. And we were seeking for a program to keep them busy. How old were they when they did the SATs? They were 10. They both did. I remember we went to the, was it the Beverly Hills? Beverly Hills High School. We were living in Beverly Hills in Los Angeles then.
Starting point is 00:27:56 And a day before the exam, we took Alex up the stairs and we went to the hallway because he was little and we wanted him to see the environment and visualize and sit on the chair. And we were just waiting in the hallway for him. And we were so scared. We said, you know, we hope that he doesn't feel uncomfortable.
Starting point is 00:28:15 And I remember the chair was so tall for him that he decided to stand and write on the chair, but all in all, he just aced it and it was wonderful. I feel bad for the kids that were flanking him on each side looking at a 10 year old taking the test next to them. The thing is, I mean, it's not about so much them getting high school at 10 or it's about our, it's not even about school or college.
Starting point is 00:28:42 I mean, I think we're the only parents, although they're in Cal State LA right now, has a special program called EAP. We tell them, you know, if you drop out of college, doesn't matter to us. I mean, for somebody, you know, my cousins say that we have more degrees than a thermostat. It was useless, all of them.
Starting point is 00:29:01 It's not about that, it's about creativity. It's about this incredible potential of the brain being often college, and I might get pushed back on this, actually kills creativity. These narrow hallways of thought can absolutely demolish creativity. So it's not even about high school finish
Starting point is 00:29:20 and finishing a high school early or college. Or grades for that matter. What can you do to bring this incredible potential of the brain to its full fruition? That's the goal. Yeah, and creating a love of learning, lifelong learning. And there is something to touch on something you said a second ago, Aisha, about depth versus breath.
Starting point is 00:29:42 Like the idea of taking one subject and just immersing yourself in it and going all the way to the end, right? And learning it as you go where it's so 360 degrees that you really learn it as opposed to catching the major concepts and then constantly switching gears in between subjects and really just hitting the surface level of everything
Starting point is 00:30:03 to check a box on a test. Yeah, absolutely. We've witnessed it firsthand with the kids where whatever subject it was, we would just allow them to immerse themselves in that subject and it becomes a part and parcel of your fiber eventually. I remember when Sophie was into social sciences,
Starting point is 00:30:24 she was into social sciences for three months straight. And then we went to, where did we go? We went to Santa Barbara to show her the missions. And she was learning about the California missions and the history of Spain and how they came to the Americas. And it was just three months of complete immersive experience into that.
Starting point is 00:30:47 And I think it really becomes a part of your experience as a person. Yeah, you're not gonna forget that. No, not at all. Amazing. All right, well, I think it would be worth taking a few moments to just share a little bit about what you do and your experience. I mean, as I said earlier,
Starting point is 00:31:09 you were on the show a couple of years ago, but there's a lot of new listeners and viewers, and I think it would be helpful in terms of contextualizing everything that we're gonna talk about. Yeah, absolutely. So we're both neurologists, husband and wife. We initially started in this field, in this journey, because we were affected by an experience with our grandparents who went through
Starting point is 00:31:39 Alzheimer's disease and they experienced it. And I remember the first conversation Dean and I had, Alzheimer's disease and they experienced it. And I remember the first conversation Dean and I had, we met in Afghanistan, by the way, when he was there from the World Bank, changing the healthcare system in that country. And I was in medical school and I volunteered with Doctors Without Borders. And because I'm a polyglot, I speak many languages. They would hire me and have me go to the harems in different villages to talk to women about healthcare and childcare and prevention, so on and so forth. So we met at a party and the first conversation we had was about our grandparents and he has-
Starting point is 00:32:19 She came, sat next to me. Right, this is a very cinematic meet cute out of like a rom-com, right? I'll tell you the true version. But I was amazed at him with all the amazing community work that he was doing, which is a whole another story. And we talked about our grandparents
Starting point is 00:32:39 and we were just so amazed at how these incredible human beings, our heroes, intelligent, just amazing humans, lost parts and parcels of themselves to the point where they couldn't recognize their children. They couldn't recognize their grandchildren. And these giants of human beings were just limited to nothingness and we wanted to study it. We actually went into the field thinking that hopefully we'll be a part of finding a treatment for diseases of the brain, like dementia and Alzheimer's. And it just kind of started from there.
Starting point is 00:33:19 Absolutely. The first meeting we talked about that and we were kind of blown away that these people with this kind of mind capacity would actually succumb to Alzheimer's. And so we came back to UCSD, which was the main dementia number one neuroscience program with Leon Thal and was a giant.
Starting point is 00:33:41 And we worked in his clinic and his lab. I should did some amazing work with the fMRIs and published there. And quickly we realized that study after study after study is failing. The mouse models would work. Those poor mice, thousands upon thousands, you throw blueberry at mice, they will get better.
Starting point is 00:33:59 I mean, every day you see a publication, this drug work. And then when you look, it's a mouse model. It never translates to humans. So around the same time, we looked at some other people's work and said, we got to find a different path. And we had a conversation, we are risk takers.
Starting point is 00:34:14 And we said, we're going to go to Loma Linda because most of the lifestyle stuff that were coming to us, the work that Elizabeth Barrett Connor and others were doing, which we were working with, was congruent with Loma Linda, which is a Seventh-day Adventist institution where they've shown lifestyle has profound effect on brain health. So it was 60 miles away or 80 miles away.
Starting point is 00:34:37 We called, like a cold call, the Dean of the university. I said, you know, I'm coming from UCSD. Can I start a brain center here? He said, absolutely. We went in and started a brain health Institute. I should have double residency, preventive and neurology. Yeah, I went to preventive medicines.
Starting point is 00:34:55 I think you and I coined the term preventive neurology. And that's what our focus has been, prevention of neurological diseases. And what we found was remarkable here. So here in Loma Linda, not Loma Linda, the Seventh-day Adventist part of Loma Linda, which is about the third of the population, you have the healthiest people in the world.
Starting point is 00:35:14 There's no question of that. The data is fairly clear. Nobody's contesting that fact. Five miles away across 10, you have San Bernardino, one of the unhealthiest place. So it's not environment. It's not even socioeconomic and racial. There's a little bit of socioeconomic.
Starting point is 00:35:29 It is the most important thing in public health access, access to information, access to resources, access to healthcare. There's a huge disparity where a seven day Adventist are health centered from the religion perspective and everything. In San Bernardino, we work in free clinic, even now half a day a week, we work there.
Starting point is 00:35:48 40 year olds with stroke by the dozens we see. I mean that much disparity. So we started shifting and working and doing research, quite a bit of publication. And we realized that Alzheimer's, stroke, dementia can be prevented. And initially when we came out like's, stroke, dementias can be prevented. And initially when we came out like 10 years ago, incredible pushback.
Starting point is 00:36:11 Whereas two years ago, we were at Alzheimer's International Conference and the big plenary talk, big sign was prevention is the new treatment. It was amazing. That's amazing. I don't think we ever high-fived in a conference, but we were just so happy that finally
Starting point is 00:36:26 they're recognizing the importance of lifestyle. How many practitioners are there in neurology right now that have a preventive focus? Goodness, I don't know of many. We don't know. Preventive neurology. Hopefully there's gonna be more. Hopefully there's gonna be more.
Starting point is 00:36:44 Big speech from somebody, but not so many people doing more. Just you guys. Hopefully there's gonna be more. Big speech from somebody, but not so many people doing it other than you guys. And it is interesting, like when you started, it was considered career suicide. It was. And to plant your roots in Loma Linda, which for people who don't know, that's one of the blue zones.
Starting point is 00:37:00 People live very long there. They tend to have happier, more fulfilling lives, and that's attributable to their faith community, their fidelity to healthy lifestyle, exercise, predominantly a plant-based diet there for the most part. All of these things contributing to not only living longer, but as you immediately begin to see better brain health. And what makes it so amazing,
Starting point is 00:37:25 almost like this perfect Petri dish for the studies that you do is that disparity because the community just outside, the sort of boundaries of that Seventh-day Adventist community is an impoverished, lower socioeconomic situation of people that don't have access to all of those things. I just repeated everything you said,
Starting point is 00:37:46 but that makes for a ripe environment for doing the kind of work that you do to kind of AB test these populations. Absolutely, I think we've learned so much about this concept. And one of the things that stands out is all about access. Access not only to healthy factors, healthy lifestyle factors, whether it's food and opportunity to move naturally or stress management and so on and so forth, but access to information and access to resources to apply that in their lives.
Starting point is 00:38:27 To have health as a part of your language every single day where you see left and right and front, behind you, there's health everywhere. That is what differentiates between two communities. You know, when the seven day Adventists, like Dean said, it's a part of their religion when they walk, when they speak, when they wake up in the morning, when they go to bed, when they interact, the core structure behind their action is the outcome is good health.
Starting point is 00:38:58 The outcome is preservation of the mind and the body. But when you veer away five miles across Highway 10 into San Bernardino, it's almost as if people are completely blind to that concept that it is possible for them to be the best versions of themselves. And you see this, their life just moving forward like automatons, not really aware of how bad their lifestyle factors are
Starting point is 00:39:26 and how destructive it can be to their health. And it's not a judgment. I mean, we wanna make sure that we, it's situation. I mean, all of us get caught up in the cycle, especially when you have to work continuously, the closest healthy food resources, 20 miles away. So with that in mind, initially we went to Cedar Sinai as the directors of brain health program there, prevention.
Starting point is 00:39:53 And then an opportunity arose where in beach cities, which is Manhattan Beach, Redondo Beach, Hermosa Beach, they had this program that Dan Buettner, our friend Dan had started. Yeah, Redondo is one of the Blue Zone cities. That's right. It created Blue Zone. And they had done such an amazing job
Starting point is 00:40:11 as far as making it a lived concept that they offered us the option of coming there and creating a initiative, brain health initiative, and also the largest research protocol in the country, community-based. So we left everything again, risk taking, who leaves Cedars-Sinai one day of clinic for Hollywood. You're insane.
Starting point is 00:40:31 But it's been, so since the two years that we talked, we've been actually growing that program. It is, there are other studies like Poynter and others that are doing clinical research on lifestyle and brain health, but it's again, more of a laboratory kind of a thing. This is a lived concept. I think we don't need to,
Starting point is 00:40:49 we don't need to recreate whether, what is it broccoli works versus beef jerky. We know broccoli is better than- Yeah, I think we know that already. There's enough information. I don't know. There's some people that are confused about that. Yeah, there's always gonna be noise.
Starting point is 00:41:06 There's always gonna be people who are gonna say the earth is flat. We'll leave them at that. You know, they can go to the edge. But it's critical that we move on and apply it not to these contrived clinical trials of a hundred people over six months or a year, to real communities.
Starting point is 00:41:22 So we're doing three of the largest projects in the country, but it's a lived model of brain health and collecting data and collecting brain health and information. Yeah, and we're really excited about that because I think one of the things that, one of the things that failed in most studies is, again, not understanding what works for at an individual level
Starting point is 00:41:47 and at the community level. I think if we find out specifically what the limitations and what the strengths are in any community and then find resources around them in their environment that would help them create a vector towards better health. That's the key. And it has to be long enough where they have support, where they have contact with the human experience of speaking with someone else or being around a supportive group to acclimate to that new healthful environment, it sticks.
Starting point is 00:42:25 Otherwise it's just me giving someone a brochure and say, broccoli is good for you. Right, right. I mean, that's a play right out of Dan Buettner's playbook, which is you have to create the environment that's conducive to the healthy choice. So then it becomes rote as opposed to some sort of burden or something that somebody has to think about
Starting point is 00:42:44 in order to do, right? It's just there in front of them. And the kind of resources of the community are pushing you into the correct lane. Right, right. And especially for a condition like cognitive decline, which is tremendous, it's scary. I mean, everybody talks about Alzheimer's and dementia
Starting point is 00:43:04 as if it's a disease that just starts at one point. You are diagnosed with Alzheimer's disease there. That's it. That's not the start. Right before that, decades earlier, there is a continuous cognitive decline that people experience. And Dean and I go to different communities for talks and before all this pandemic. different communities for talks and before all this pandemic, when you go into communities where, you know, their health literacy is lower, for example,
Starting point is 00:43:31 they haven't had any resources, you actually experience the cognitive decline when speaking with individuals in their 50s and 60s before they even are diagnosed with Alzheimer's disease. And it's scary and the numbers are scary. And we never address that. And it's not just brain health. You hear about brain health all the time. You read great books, but it's that self that is under attack. It's that us, it's that us-ness, you know, it's the sense of being aware and being present and being able to experience life. That is, we're being robbed of that.
Starting point is 00:44:12 You hear brain fog, you hear memory problems, but not being able to be present for each and every moment in your life. That's what's taken away from people. And that's scary. And if we have a way of making people attuned, where we alarm them that listen, there is something that you can do where you don't have to go through this. I think that would be a great opportunity
Starting point is 00:44:38 and it's a great gift for us to be able to serve people that way. Right, so conventional medical wisdom, at least until recently is or was that Alzheimer's is something that is going to be visited upon many, many people when they reach, I don't know, late 60s, 70s, something like that. It's basically a genetic predisposition
Starting point is 00:45:07 in more cases than not, it's a death sentence. There's not much we can do about it. We can't cure it. We can't prevent it. We can kind of maybe manage it with some drugs, but really there isn't much that we can do. And we're working on a cure, but we aren't very close. So how much of that is accurate and where does your work fit in
Starting point is 00:45:24 to kind of upend that paradigm? So the genetic component, let's start with that. We know the genes that are involved in Alzheimer's with new techniques like GWAS analysis and others where you take large populations who have Alzheimer's and those that don't, you look at the genetic differences. We know about more than 30 genes that are involved in Alzheimer's.
Starting point is 00:45:45 Of all Alzheimer's cases, the percentage that's driven by genes, a hundred percent driven by genes, meaning that if they have these genes, they'll get it. And in genetic terms, it's called a hundred percent penetrance, like Huntington's disease. If a person has the Huntington gene on that chromosome four, they'll get it.
Starting point is 00:46:05 But the percentage of Alzheimer's cases that are like that is only up to 3%. The other 97% are affected by genes, but they are only risk genes, meaning that those genes increase your risk, but they're not a foregone conclusion. It doesn't mean that you will get it. The next highest risk gene is APOE4.
Starting point is 00:46:31 About 2% of population is APOE4 positive. So if you have one of those genes coming from one parent, your risk goes up four times. If you have two, one from each parent, about 12 times. That number varies, but roughly those are the numbers. So even if you have two, one from each parent, about 12 times. That number varies, but roughly those are the numbers. So even if you have two genes, fully loaded with these bad genes, 50% of people get the disease.
Starting point is 00:46:54 The other 50% don't get it. Why? And when you look at the data coming from Nigeria, where the population had higher proclivity for APOE, when they came to US, the disease went up. When you look at the studies that came from UK, which lifestyle increased your risk six times, even in lieu of APOE4, you realize,
Starting point is 00:47:14 even with the higher genetic risk of APOE4, lifestyle is a way bigger factor by far. So all of the genes involved in Alzheimer's, except for those 3% or three genes, are all our lifestyle genes, how your lifestyle affects those genes, which means you have control over it. Even the most benign studies,
Starting point is 00:47:39 the ones that had minimal effect, the MIND study and others, MIND study just looked at diet, very well done study. Just a diet adjustment, reduce your risk of Alzheimer's by 53%. Wow. And that was a watered down version of the diet we think is optimal.
Starting point is 00:47:58 How long would you need to be eating and eating in that certain way leading up to it? It varies from person to person, their background, other things like if they had multiple head traumas, childbirth, like multiple variables. But in reality, if you're on that diet for several years, you continually reduce your risk. Like smoking, if you've smoked all your life and if you come off of smoking, come off of that bacon,
Starting point is 00:48:22 come off of that, well, then the more years you pass, I believe in smoking it's after five years. Five to seven years. Five to seven years you're back to baseline. Meaning you're back to the lowest risk factor. So the longer you stay on a healthy lifestyle, which is exercise and all the things that we say, and especially if you do all of them,
Starting point is 00:48:45 the reason I say all of them, coming back to our grandparents, one of the elements is cognitive reserve or what the term you and I love, idea density. You know, we say that if we have a musical band, that's gonna be called idea density. They had idea density. Yes, it's a great, great concept.
Starting point is 00:49:04 They both, both our grandparents had immense idea density and philosophers think, but they succumb to Alzheimer's. Why? The other elements weren't taken care of. They had diabetes, cholesterol, high blood pressure, horrible food. Quite sedentary, bad food. Didn't exercise, philosophers are not supposed to exercise for some reason.
Starting point is 00:49:23 But so you have to do all of it. Right. So we're gonna get into these lifestyle interventions, but before we do that, let's talk about the brain more generally. We sort of think of the brain as this mysterious black box that is unknowable and something that sits outside of our body, right?
Starting point is 00:49:53 Like there's our body and then there's our brain and these things don't really overlap. But in truth, brain health is really, it's about vascular health in the same way that heart health is, right? Like we're dealing with, I don't know how many zillions of arteries that are going into the brain,
Starting point is 00:50:16 putting things into your brain and taking them out, et cetera. And when you think about heart disease, we all know we're trying to not have plaque in our arteries and keep those pipes running clean. And brain health is really not that different, is it? That's very true. You put it beautifully. When you look at the brain, it's about three pounds,
Starting point is 00:50:38 like jello, it's like hard jello when you hold it in your hands. And it's about 2% of your body's energy. And when you look at in your hands. And it's about 2% of your body's energy. And when you look at the tissues and the vessels, they're the same vessels that are in your heart and in your kidney and your body. I'm a vascular neurologist, so I teach a lot of anatomy to medical students and residents about the vasculature of the brain. But basically, you have arteries shooting from your heart going through the neck. There's two major ones in the front, the carotid arteries and the vertebral arteries. And these are the major vessels that take blood
Starting point is 00:51:08 to your brain. And there's just branching of these arteries. And somebody actually calculated this, but if you put the vessels in your brain end to end, it would span about 400 miles. So just imagine all of these tiny hairline arteries taking in oxygen and nutrients to these susceptible areas of the brain for this incredible organ to function. And at any moment, our brain, as little and as small as it is, it can consume up to 25% of the body's energy.
Starting point is 00:51:39 So just imagine the amount of work that it does. And if we don't address vascular health, and if we don't really take care of it, it will succumb to disease. You know, we always say, and our cardiologist friends don't really like that, but we say the rest of the body is there to carry the brain. And it essentially comes down
Starting point is 00:52:01 to the same pathological processes that affect the brain, that also affects the heart, the kidneys and the other systems as well. In fact, recently there was a publication by Dr. Hitchinsky from Canada. And he summarized the concepts, but the vascular factors actually predate, you know, the popular thing that we hear amyloid plaque and tangles, vascular pathology predates those things.
Starting point is 00:52:27 With the newer tools, with newer, more sophisticated MRIs, you can see 20 years earlier when somebody starts having some pathology. And the microvascular disease started way earlier. So if we take that into consideration that in your 20s, 30s, 40s, the things you do isn't gonna just avoid Alzheimer's.
Starting point is 00:52:47 And we think absolutely for a great majority, 90% plus, you can avoid Alzheimer's. But more importantly, sustain cognitive capacity and grow cognitive capacity. We know that we don't use the full potential of the brain. And in fact, as we get older, one of the areas that's affected the most is focus for two reasons. One is the focus center shrinks
Starting point is 00:53:10 as well as the fact that we're overwhelmed. Multitasking, which we say, there's no such thing as multitasking, it's doing multiple things badly. Right. It just accumulates and accumulates. But if you manage and control focus, you can actually grow your cognitive capacity as you get older. That's our goal because if you manage and control focus, you can actually grow your cognitive capacity
Starting point is 00:53:26 as you get older. That's our goal because if you do that, if we've addressed, this is critical, if we address the vascular factors and the fact that we can grow the brain, we can hit all these communities that are now devastated with cognitive decline. And we see them all the time.
Starting point is 00:53:43 Right, so neuroplasticity then becomes a function of vascular health. Absolutely. Yeah, super interesting. When we think of, again, back to the kind of heart analogy, we think of plaque buildup in terms of deteriorating heart health. With brain health, it's amyloid plaque, right?
Starting point is 00:54:06 Which is different, but kind of the same, like it's blocking these passageways and that's ultimately what leads to stroke. Correct. Is that right? So no, with stroke, it's atherosclerotic plaques. It's different. Amyloid actually accumulates outside of the neurons and stops the communication between the neurons.
Starting point is 00:54:26 So it's a little different. It's in between the neurons. In between neurons. Right, okay. The neurofibrillary tangles, which is the tau is inside the cells. There are two things happen. One is the amyloid plaques and the neurofibrillary tangles.
Starting point is 00:54:38 They're connected in many ways. We are learning more and more. The neurofibrillary tangles are really interesting. There are these scaffoldings that hold the microtubules inside the cell steady. The microtubules are, it's almost like we're doing, we just got the Oculus and I was doing the, and it's a crazy thing.
Starting point is 00:54:57 We were doing the rollercoaster thing. And you see this rollercoaster throughout the planet go. And the microtubules are these pipelines throughout the cell for transport, for structure and everything. And the tau molecules hold them together. All of a sudden they get phosphorylated and they come off. And then you see these scaffoldings fall apart
Starting point is 00:55:18 and clog together. So for many years, we've thought that that's a separate process. It's a genetic proclivity. And there is, there are those 3% variety. But we know that inflammation also attributes to that, multiple traumas to the head, infections, multiple pathways to trauma, oral hygiene, and all of that,
Starting point is 00:55:40 as well as vascular factors. So wait a second. So if vascular factors and inflammatory factors are contributing to even those tau and amyloid cofactors, we have control over those. Right, right. Yeah, so that's amazing. Like just the realization that we do have some domain
Starting point is 00:56:04 over this thing that we've always kind of thought of as just looming out in the distance and it's either gonna happen or it's not gonna happen. Oh, absolutely. Just understanding that our day-to-day habits affect those small little arteries in our brain. When you have sustained damage to the arteries or sustained attack, let's just say,
Starting point is 00:56:26 you know, an attack to the system. So the body and the brain especially is constantly trying to revert any damage. You know, we have damage control mode and we have a thrive mode. And the goal is to be more in the thrive mode rather than damage control. And the damage comes from, say, for example,
Starting point is 00:56:44 vascular damage comes from sustained high blood pressure. Blood pressure is one of the most important risk factors for so many chronic diseases that we're dealing with. When we have uncontrolled blood pressure, the small blood vessels in our brains, they essentially collapse on themselves. And on MRIs, what we see is these patterns called white matter disease.
Starting point is 00:57:05 White matter disease is when there is damage to the blood vessels. And so those parts of the brain are inflamed, but they don't really function very well. A lot of times they were called nonspecific white matter disease, but we're actually learning more and more about them. And they have been correlated with cognitive decline. They've been correlated with strokes. And we know that lifestyle factors can really alter them, can change them. Diabetes is another risk factor. Damage to the inner linings of the arteries can cause damage. And there are parts of the brain that require, well, all parts of the brain, but specifically the ones that are responsible for, say, for example,
Starting point is 00:57:41 encoding memory, the hippocampi or the frontal lobe where the judgment sits or the emotion centers. When the damage, when the blood vessels are damaged in these areas, we really can't function anymore. And that's when you see cognitive decline. It's interesting with blood pressure, that's something that you get checked. I don't know, I mean, when you're younger,
Starting point is 00:58:02 barely ever when you go to the doctor for your checkup, but it feels like something that should be monitored much more regularly and closely. Absolutely, because it's variability and high blood pressure that matters as well. And I'm so excited about new technology coming up, whether it's the watches or any wearable devices that can give just a quick update on how someone is doing a live update.
Starting point is 00:58:30 I think that's the most important thing. You can't really wait for every three months or every year to get your blood pressure checked. We see people in their forties and fifties coming in with extremely high blood pressure and we have to like treat it rapidly with medication to prevent strokes and damage to their body. It's quite ubiquitous.
Starting point is 00:58:47 Before we get into the lifestyle interventions, I wanna talk about this neuro paradigm that you guys have come up with. Perhaps it would be good to differentiate between cognitive decline, dementia, Alzheimer's, and strokes. Like let's get clear on like the different, what the difference between all of these things.
Starting point is 00:59:08 Terminology. Yeah. So dementia is the umbrella category and dementia is the rough definition of it is when a person is having cognitive decline to the extent where they can't do some of their activities they could do before, Not because of physical limitation, because of cognitive limitation,
Starting point is 00:59:27 be it memory or processing capacity or things of that nature. For example, if they could drive before, now they're having difficulty driving because they can't think their way through the directions. They could take care of their medications, they can't take care of their medications now. If they were doing the finances,
Starting point is 00:59:44 they can't take care of the finances. You have to be careful there because as we get older, without knowing, you kind of pass off your activities to others. And when you've asked the family, oh, I don't know, I don't see a difference. But what happened is over time, that responsibility was passed on. But when you truly check them, they have had loss of capacity. That's dementia. It's an umbrella category. Alzheimer's is a subtype of that dementia. It's a major one, 60 to 70% of all Alzheimer's,
Starting point is 01:00:15 dementias is Alzheimer's, but there are other types of dementia, such as frontotemporal lobe dementia, Lewy body dementia, vascular dementia, Parkinson's dementia, and many others, Huntington's dementia, but Alzheimer's is the biggest one. They manifest differently and the causes are somewhat different. Although we think that all of them are affected
Starting point is 01:00:33 to different degrees by lifestyle. Some of them are more genetically driven. Like frontotemporal lobe dementia is more genetically driven. That dementia is early in life. Sometimes it affects language. So like primary progressive aphasia, the person can think,
Starting point is 01:00:50 but their language is affected disproportionately early on. Lewy body dementia is more movement and hallucinations and visual spatial changes. And it's a different pathway. It's a synuclein body. It's a different kind of protein. Alzheimer's, and this is something that everybody's familiar with. I'm gonna say it, but I wanna state it kind of protein. Alzheimer's, and this is something that everybody's familiar with.
Starting point is 01:01:05 I'm gonna say it, but I wanna state it ahead of time. Don't be scared. We all have some of this. Where short-term memory early on is disproportionately affected compared to long-term memory. So a lot of, especially men, they say, oh, I'm fine, Dean, I'm fine.
Starting point is 01:01:19 I can remember 50 years back when I was in, you know, and, but I just, you know, I'm having difficulty with the breakfast. Well, that's what's happening. Right. The short-term memory, which is in the hippocampus has affected disproportionately. And it's the fastest growing epidemic,
Starting point is 01:01:33 well, outside of COVID now in the West. We're talking about about 6 million individuals in US, 35 million worldwide. And this number, we have to read, we have to change the number every time we talk. Every time we have a PowerPoint presentation, we have to change these numbers unfortunately. I read recently 47 million people worldwide.
Starting point is 01:01:52 Worldwide, yes. So we have to change it again. And estimates are that it's projected to triple by 2050. Yes. It is. So everybody's gonna be impacted. Everybody. In fact, even now, if you ask families,
Starting point is 01:02:08 I did my PhD thesis around community-based participatory research in the minority populations and those populations are in low socioeconomic populations. Every family has been affected, but they haven't called it dementia or Alzheimer's. That's how ubiquitous it is already. Now, the numbers as far as cost is even, I mean, the human component is incredibly bad
Starting point is 01:02:36 because it's affecting everybody. And we'll talk about what COVID did this in the tsunami. This population was the most affected population in the world, the Alzheimer's population. But the cost, the second costliest disease is heart disease at 120 billion, cancers, 70 billion combined. Alzheimer's, direct cost, 305 billion,
Starting point is 01:02:58 indirect cost, 240 billion right now. And it's climbing up to $1.123 trillion directed in direct by 2050, which will collapse our system altogether. Yeah, the system's already broken. It can't bear that kind of load, but is that excessive cost attributable to the slow burn nature of this
Starting point is 01:03:20 and the extent to which kind of live in care is required for these people to live their lives or where's all that money going? It's sad, it's going, well, the direct cost is going to Medicare medications, which really don't do much. Not even the pharmaceutical companies claim that Aricept and Amanda reverse or slow down the disease. It doesn't, they're just symptomatic.
Starting point is 01:03:42 The disease is continuing, it's just doing a little bit of help with the symptomatic, but a lot of money spent there in care, nursing home and others. The indirect cost is you should see the people, the families that can afford it the least have to stay home to take care of the loved ones, which means hours lost, work lost,
Starting point is 01:04:00 and all of that happens with it. Right, devastating. And on top of that, we have COVID right now and COVID is really drastically impacting the Alzheimer's community, right? Like I saw on Twitter like two days ago, there was a Barron's article about this that was like trending, you know,
Starting point is 01:04:16 that what is the future of Alzheimer's look like? And I know that you guys have spoken about this. What is it about COVID that's disproportionately impacting the Alzheimer's community in such a bad way? It's a multifactorial, like Dean said. I mean, the numbers are scary. We were actually reading an article the other day and Alzheimer's patients are dying faster, not because of the infection or COVID related consequences, but because of their disease.
Starting point is 01:04:50 I think the number was 16% higher rate of mortality in that population. And it has to do with loneliness, disconnection, isolation from human experience. Connection. Isolation. Isolation from human experience. And, you know, the brain is hungry for information and for connection. And when that withers away, when that's withdrawn, you see patients succumb to Alzheimer's disease. And there's so many stories that we could tell you from our clinic and just talking with some of the caregivers where these lovely patients are completely isolated in a nursing home and they don't see their children or their loved ones.
Starting point is 01:05:32 And the mind is such where if they don't get that conversation, even a phone call or mundane conversation about food or clothes or just a normal walk in the park, basically the brain just completely withdraws and withers away. And there's profound changes and decline in their cognition to the point where they forget to do their basic activities of daily living. They forget to eat, They forget to take care of themselves. And slowly and gradually that causes disease and death. And we've seen that so many times, unfortunately, more than we would wish to see.
Starting point is 01:06:16 And this is a population that's most vulnerable. Right, right. Anxiety, I say, you and I, Aisha and I, we treat anxiety more than we treat the memory component because it's a quality of life issue, isn't it? I mean, and patients with Alzheimer's, anxiety is ubiquitous and rapidly growing. I give an analogy like, and it's not,
Starting point is 01:06:39 and a patient with Alzheimer's initially feels like they're in their basement, now living in their basement, not really, but that discomfort. Then in the neighbor's home, then in a different city, then a different country, then ultimately in Mars with Martians coming because nobody's familiar. That anxiety compounded with loneliness,
Starting point is 01:06:57 with isolation, with separation, is what forces the brain to actually collapse upon itself. We think that the main reason for the greater mortality is not so much that because they were in closed environments, therefore they suffered from COVID, but because of the greater loneliness in the population that could afford that the least. Yeah, I mean, I've had some personal experience
Starting point is 01:07:21 with people that are suffering from Alzheimer's and my sense, and this is just purely like anecdotal is, well, first of all, you can read the anxiety coming a million miles away. Like you can tell these people are not settled in who they are, that there's some confusion. And what I see more often than not is almost like a veneer of denial or an effort to like comport themselves
Starting point is 01:07:48 as if they know what's going on, like out of fear that somebody might know that something's amiss or awry. And I'm often left wondering, like what is the level of self-awareness that this person, this patient has about the nature of their condition? Like, are they aware that they're suffering and they're actively trying to put up a front
Starting point is 01:08:09 or is this something that just occurs with this disease? Like what is their interior experience of what's happening? It's tough to know because it varies, but it's the fight or flight, isn't it? So, I mean, I've seen this repeatedly. Your autonomic manifestation and behavior is fight or flight. And my grandmother was a powerful woman. And I actually, in the last years of her life,
Starting point is 01:08:33 I actually shared the room with her. And being a stupid teenager, I didn't appreciate that experience, which was profound and important, and I should have been more aware. But that's, she, as part of, this person that would face you, would talk to you with clear language
Starting point is 01:08:51 because she was, she knew that, that in order to be in a world of men, she had learned very early on to be very succinct and clear. She started turning away from the world. So the withdrawal. So you see a lot of people just withdrawing, not being as involved, not being. And in her case, she actually world, so the withdrawal. So you see a lot of people just withdrawing, not being as involved. And in her case, she actually turned around
Starting point is 01:09:08 towards the wall. She would actually start facing the wall. That's a withdrawal. The others push away, the fight. And often it's not a conscious awareness that something is wrong. It's a discomfort that manifests in those two outcomes. And if people are aware of that, then you realize that,
Starting point is 01:09:29 and that's why a lot of bad interpersonal relationships early on, because people don't know that the Alzheimer's is coming and the manifestation is this behavior and turns out really bad. And with my grandmother, it was that, it was the withdrawal. But a lot of people actually then have this pushback. Right. Pushback,
Starting point is 01:09:49 which is the discomfort. Discomfort, something is wrong. And the only tool I have is pushing back. Right, get away and let me, leave me be, right? And what is the appropriate response? Like, I'm sure you've seen all kinds of different dynamics with how people interact with somebody who's suffering. Is there, have you come upon an appropriate kind of way
Starting point is 01:10:11 of interacting with somebody who's in this space that's more productive than other ways? Yeah, I think again, it varies. It depends on the history that the caregiver has had with the patient, the individual with Alzheimer's to let them know that it's very important to differentiate between the individual and the disease. They're two separate things and entities. And that actually makes everything fall in place. Because if, say, for example, Sally is someone who has Alzheimer's disease. And Sally used to be an amazing human being, had her own job, raised a family,
Starting point is 01:11:09 fantastic in the community. She sang, she was part of her church, so on and so forth. And slowly she started forgetting things and now she can't do any of those things. So the family and the caregivers should make sure that they remind her of who she was and who she is. Those stories of the things that she did are essentially her medicine and a reminder of who she is and how she's contributed to this world.
Starting point is 01:11:34 And the symptoms of forgetfulness, of making mistakes, of saying strange, inappropriate things or acts that are inappropriate, that's the disease. That's not her. And that resolves some of the anxiety within the patient, with the caregiver. Caregivers tend to have this need to fix things. We always want to fix people. We want to fix patients. There's no need to fix anything. We wanna fix patients. There's no need to fix anything. And somehow when you differentiate the two, then that desire to fix goes away and you just focus on the beautiful stories
Starting point is 01:12:11 and the memories that that patient has already had and focusing on the moment. Beautiful. And Dean actually has this beautiful, I love that thing that you do with, yeah, the islands of consciousness. So my attempt at defining consciousness, if there is such a thing,
Starting point is 01:12:28 is there are islands of consciousness. So the first island is when you're three years old or so, and you become aware of yourself as separate from the universe, from the world. And then there's the island of the mother and the island of the father and the island of the family and islands of job and so on and so forth. Some of them are more powerful than others.
Starting point is 01:12:46 That's why the most lovely thing you see is when a husband has dementia and they don't recognize anything. And then the wife comes in and you see this, it's almost as if the greatest party in the universe just opened up doors, you know, because that island that this wife is still the island, the central island that's connected.
Starting point is 01:13:07 So keeping those islands connected early on with cognitive decline is critical, getting rid of the damage, which is the food and exercise, and also building connections, those billions of connections that we can't create so we can keep the tethers into the different islands. That's why people remember long-term better than shorter.
Starting point is 01:13:27 So one of the things we can do to stabilize at least for a while is have 20 great stories from the past that you've lived those experiences. When you went to some island as a family or some resort or somewhere, and you had that enjoyment and he or she remembers it, build on that, even embellish it more, and you have those 20 stories. The greatest anxiety reducing tool
Starting point is 01:13:54 that I've ever given my patients had nothing to do with a prescription. Although I write this in prescription actually, is build those 20 stories. And whenever you see the first signs of anxiety, throw that in. That long-term island, that big island takes over. And I've never seen anything like that
Starting point is 01:14:10 where the conversation just goes there and the anxiety is just resting. And you build on those islands, especially early on, build on those islands of memory and connect them further on. And that becomes your best anxiety reducer. You know what's another great island? Which actually passes way beyond the loss of language, music.
Starting point is 01:14:33 Repeatedly we've seen where this person can no longer connect with anybody. And now they can't even remember their partner. You put that one piece of music from the 40s or 30s that they loved. And then you see them just moving their fingers to the music and just calming down. So you can build around those islands
Starting point is 01:14:52 for the people, for the individuals that are more advanced. For those who haven't developed Alzheimer's is building those connections so that the islands can keep connected. That's where the ultimate consciousness, we believe that consciousness as we define it is when multiple of these islands are connected. So you can see a meta version of yourself
Starting point is 01:15:12 within all these islands. So you use those stories to create a lattice work or like a matrix that forms the underpinnings of identity. And that gets rooted in the person. This is not fair. All I'm doing is repeating what you said. No, but you do it so much better. That's beautifully put.
Starting point is 01:15:29 Well, nobody wants to befall this fate, right? And when we're young and vital, we think we're bulletproof and this is never gonna happen, but these diseases start to take root early in our lives. We don't see the symptoms for many years. So it's all about these habits that we form around diet and lifestyle. So set us up with this paradigm
Starting point is 01:15:53 that you guys have come up with, and we can walk through some of these habits that you guys have realized have been extremely helpful in managing symptoms and preventing people from headed down this path. Sure, so not to go into the depth and details of the science, which we could do, and we probably will spend some hours just going into it. But when you look at the basis of the pathology
Starting point is 01:16:19 that takes place in the brain and the body for that matter is just a few processes. These are inflammatory processes, oxidation, abnormalities in metabolism of glucose or energy and abnormalities in the metabolism of lipid. These are the four main pathways that cause damage to the vasculature, the blood vessels in the brain, and it causes damage to the neurons
Starting point is 01:16:44 and the neural connections as well. And when you look at the mechanism of how these come about, they're very closely linked to your lifestyle. So it has to do with food, with the way you move and exercise, with stress management, with sleep, my goodness, sleep, such an important part of our day, and also how we connect socially, emotionally to our communities. And whether it's studies coming from, say, for example, in Columbia University, where I trained from the Northern Manhattan study
Starting point is 01:17:17 or from the Rush University studies or from the Adventist Health study, different studies from around the world. When you look at the factors that stand out that contribute to better brain health, it's nutrition, it's exercise, it's stress, it's sleep. And the one that we added is cognitive activity. So-
Starting point is 01:17:39 That's the O, the optimism. That's right. So when we wrote the first book, we came with this acronym, N-E-U-R-O. Of course, it's self-explanatory and it was good because we're neurologists and helped us a lot too. It all came together.
Starting point is 01:17:54 It came together. And, you know, N is for nutrition, E is for exercise, U is for unwind, which is stress management, not just getting rid of stress, but increasing good stress and getting rid of bad stress. And R is for restorative sleep, deep restorative sleep that helps cleanse the brain and has its own function
Starting point is 01:18:12 and optimization of cognitive activity. Right, some of these, if not all of them, feel like common sense. And yet also, I mean, I think the nutrition piece, everybody knows you gotta, if you wanna take care of your body, you gotta eat right, right? Sleep, exercise, challenging yourself mentally,
Starting point is 01:18:34 being in a community of people that you're connected to. These are all things that we kind of intuitively know are good for our health. The nutrition piece, would you say that's, is there one that stands out as more important than the others or do these all work? Obviously this is a holistic thing, so they're all interconnected,
Starting point is 01:18:52 but if you had to pick one, is that even possible? I don't think it's fair. I guess if you don't sleep at all and you eat a perfect diet, it's not gonna matter. No, I think it's the multifaceted nature of this that actually makes a big difference. And when you look at different communities and individuals as well,
Starting point is 01:19:08 they might excel in one thing, but they might be falling behind on others. And I mean, it's understandable. We can't really control everything, but all of them are important. What would you say? No, I fully agree with you. I think all of it has to be done.
Starting point is 01:19:22 And it's incredibly empowering to know that because every time we say that somebody says, oh, my I think all of it has to be done. And it's incredibly empowering to know that because every time we say that somebody says, oh, my friend did all of it, but no, none of us did all of it. And we're talking about living a, the food part is pretty specific. I mean, we don't have that many communities that lived in the way that we were talking about.
Starting point is 01:19:41 And we'll talk about it, as far as whole food plant-based. We're talking about exercise, significant exercise. We're not talking about whenever we talk to our patients, they say, oh, Dean, I'm fine. I do the gardening, I do the walking. No. Or for example, my patients, when they say,
Starting point is 01:19:56 I'm walking all day long from my living room to the kitchen, back to the living room. That's not exercise. It's gotta be significant amount of exercise. And then stress management. It's not about just getting rid of bad stress. By the way, none of us are doing that well. And it's not just because you meditate.
Starting point is 01:20:12 Meditation is phenomenal, but it's gotta be an all day, but also about good stress. One of the things that actually gets people to the dementia stage fastest is what they did throughout their life as far as cognitive activity and challenge. That's profoundly important. Sleep, none of us do sleep well,
Starting point is 01:20:30 just because we took some medicine. We're talking about restorative sleep where people go through the circadian, you know, the four phases of sleep, four to five times a night deeply. We invest in incredible resorts. We've been invited to different venues. I say, take that money and, well, I mean, I can tell,
Starting point is 01:20:46 put it in your bedroom. There's a reason why we're knocked out. Evolutionarily, how would it make sense that you're subject to being mauled by bears and lions for one third of your life, unless it was that important? So sleep and investing in sleep is profoundly important. We study, we're doing the largest one with the sleep study is shows that 70% increased risk of dementia for those who have bad sleep.
Starting point is 01:21:13 And then there's optimization, which is challenging mental activity. If you think you retire and you can go slide out on the beach that's great for a few months, but if you continue, that's going to be the fastest point of decline for cognition. Because if this brain, which is consuming 25% of your body's weight
Starting point is 01:21:33 and realizes, oh, I'm not being used, especially at a time where you're aging, you know what it will do? It will actually shrink more rapidly. So all of it has to be done and all of them have to be done together. But the beauty is if they're done and if it's not just a diet du jour or the new resolution run or walk, and if it's lifestyle, and especially if it's lived lifestyle, which is what we're trying to
Starting point is 01:21:56 do in communities, we're talking about 90% reduction in Alzheimer's, dementia, stroke, without any biohacking or vitamin du jour or any of that stuff. With regular things you have in your environment. And I think one of the focus of our study, which is the largest community-based study in the country now in beach cities is the applicability of this knowledge. I think we have tremendous amount of information about the kind of diet and the kind of exercises that are good for the brain, even stress management, so on and so forth.
Starting point is 01:22:30 But what we haven't really focused and what I don't see much of is bridging that gap between the knowledge that we have, the incredible amount of information that we have and how people apply it at their homes. That's always the trick. It really is. It really is.
Starting point is 01:22:49 And so I think more focus needs to go towards that, the translation of all this amount of information we have. And people aren't very good at estimating or calibrating, you know, how they're adhering to any of these things anyway. Most people tell you, I exercise, like you were saying, like I exercise or, you know, I eat pretty good, like, you know, everything in moderation.
Starting point is 01:23:12 And, you know, these things are divorced from reality more often than not. Yeah, absolutely. My two least favorite words in language is motivation and moderation. Motivation is a top-down word that has no denominator. What is that? It's almost like puts pressure on kids. Like if I don't have it all the time, something's wrong with me. I don't have motivation all day. So it's important to operationalize
Starting point is 01:23:40 motivation and small successive successes that get you that little dopamine and serotonin release. So it's not about the goal. It's not about a, it's about the process. If it's not reduced to process that's in your lived life and you don't enjoy that process, it even if you achieve the goal, it then becomes anticlimactic. Okay, I just did this.
Starting point is 01:24:01 Now what? Oh, I fall down to the baseline. So we have to create environments where the process is the thing in itself. Don't wanna sound like those philosophers. The thing in itself is the process, not the goal, not the diet, not that. So that's where the change has to happen.
Starting point is 01:24:17 And then the other word is moderation. Moderation is a word people use to get out of doing things. Let's be honest. As soon as you say, oh, Dean, it's all about moderation, but you just had four steaks. Where's the, what part of moderation? I'm not judging people, but we have to say, this is the optimal that we know
Starting point is 01:24:38 to the best of our knowledge today. And that's where the humility of science comes in. When we, you know, people say, but Dean, you just changed your perspective on olive oil. Yeah, because it's not about me. It's not even about neuro. You can throw away neuro. It's whatever science gives us and it might not be perfect,
Starting point is 01:24:54 but it's a methodology that's changeable not with people's ideas, but with a process. And if it changes tomorrow, my ego is not affected. So we have to kind of move that. And if we do that, I think we can really address this calamity, which is cognitive decline, which is affecting every community we're seeing. So let's dive into the nutrition piece.
Starting point is 01:25:36 Whole food plant-based diet is your preferred protocol here. So of all the, you know, the, within the acronym neuro, perhaps that might be the most controversial for, you know, for the average person to get their head around. So how did you arrive at this being the diet that you're recommending? Right, so when you look at different epidemiological studies and even clinical trials on diet and brain health, the elements that stand out, they're all plants. Whether it's studies coming from Northern Manhattan study
Starting point is 01:26:10 or Adventist study and all these other epidemiological studies that I mentioned earlier, the foods that have the most anti-inflammatory agents, that have antioxidants, that have a proper synergistic combination of micronutrients and macronutrients happen to be plants. And, you know, as much as we try to stay away from calling foods superfoods or, you know, good foods and bad foods, there are some that
Starting point is 01:26:38 seem to be more beneficial and there are some that seem to be harmful. And so when you, and I've had the opportunity and the privilege to work with some databases, the California Teacher Study. And what I did was I studied how the Mediterranean diet, which everybody talks about, is structured and made. And when you look at the Mediterranean diet or the mind diet, again, the food that come on top are vegetables and plants. They're fruits and legumes and nuts and seeds and whole grains, unadulterated plant based foods. And the more of these people consume in different communities, the less stroke they
Starting point is 01:27:19 have, the less Alzheimer's disease they have, the less chronic diseases of aging they have. And they've been associated with vascular risk factors like high blood pressure, high cholesterol, diabetes. So lower of these tend to actually improve brain health. Now, I know that there's a lot of noise out there and there are different dietary patterns and there's always this fight, there's a lot of diet wars going on. But when you look at the science and the mechanism, it always comes towards plants. And it's a spectrum, right? So how much do you want to stay,
Starting point is 01:27:54 how long and how much do you want to stick to the healthier foods? That's what determines better brain health. When I hear Mediterranean diet, I'm always befuddled because I'm not sure whether they're referring to a robust, panoply of fruits and vegetables and nuts, seeds and legumes or we're talking about wine and cheese and olive oil.
Starting point is 01:28:22 As somebody like in at least in the scientific context, when you're doing these kinds of studies, like how do they define that? Oh, it's not that difficult actually. So there's, there are different processes and there are mechanisms and statistics and in science where you do factor analysis and you see what food stands out.
Starting point is 01:28:38 And that's one of the things that we are actually doing in one of our studies to see, you know, what is the effect of specific foods on brain health? And yeah, wine, cheese, pasta, when you see the Mediterranean diet advertisement on the magazine, so, you know, pretty lady sitting next to a lake drinking wine, but it's not that, it's actually the foods
Starting point is 01:28:56 that are unprocessed and plant-based that seem to stand out. But again, you know, even science has its flaws and there are some studies and some study that we were actually reading about a couple of days ago just came and it was published in a reputable journal saying that cheese, daily consumption of lamb
Starting point is 01:29:21 and up to a bottle of wine seemed to reduce the risk for Alzheimer's disease. And that plants were actually bad for you. So it was just this manipulation of data. As compared to what? Like how was that study set up? The study was well designed. The source of funding is questionable.
Starting point is 01:29:37 So we won't go there. But so it speaks to how science can be manipulated. Even in the right environments, it can be manipulated. Depends on what variables you throw into the formula, right? If you don't take into consideration the socioeconomic status, I mean, who eats cheese, wine, and lamb? Higher socioeconomic population,
Starting point is 01:29:57 which means that they probably took care of themselves. And who did you compare against? People who had very low socioeconomic and therefore they had low resources that they actually had other vascular risk factors and other things. So data can be manipulated, but the massive, massive body of evidence
Starting point is 01:30:15 and California teacher study, Aisha actually was the main author of this, 133,000 people over 20 years. Adventist health study, 97,000 people over 50 years. We're talking about the Harvard study and women's health study, large studies. The massive data shows, and Rush study, same thing, a large study, that the dominant things that are helpful
Starting point is 01:30:38 are the plants and vegetables and less processed food. So at the minimum, if people want to do something towards health, and if they don't even agree or they can't make the changes, which then they should reduce the processed food. You know, we know that even among the meats, which if you go from beef jerky towards fish,
Starting point is 01:30:58 you're more healthy. So we actually say, you know, we are plant-based and we think that that's the best, even plant-based, we don't say vegan because vegan can be unhealthy. Right, that's like saying Mediterranean diet can mean many different things. Exactly, that's true.
Starting point is 01:31:14 We say plant-based, but thought out, planned. For example, that we are now pushing a little bit more olive oil and even they're quantitatively less on the less side, because we think it can help with both consumption of the food, as well as absorption of vitamins. And also the data shows that we were just at the end of a big review.
Starting point is 01:31:36 As far as supplements, we don't push a lot of supplements, but for certain populations, developing brain and aging brain, and those who are going through pregnancy, omega-3s, whatever your source, seem to be, there's trend against science that there might be need for it. So there's data, you go with the data, we do, but it looks like the whole food plant-based diet
Starting point is 01:31:56 seems to be by far most beneficial because of two reasons. It gets rid of the process and all the negative elements, the vascular stimulant, the inflammatory products, and also gives you all the nutrients you ever need. All the deficiencies that you hear in the media, iodine deficiency or B12 deficiency, either they're not real or they can be easily mitigated
Starting point is 01:32:19 while retaining all the benefit. That's why the diet has been shown repeatedly to be beneficial. Right, well, let's dive into that a little bit more deeply. And maybe we could start with fish. I mean, you hear all the time, especially in the context of brain health, like, oh, fish is good for brain health. And there are studies that say fish is part
Starting point is 01:32:39 of a healthy diet. Typically those studies tend to be using fish as a comparison to beef and chicken. So it's not being compared to a whole food plant-based diet, but is it possible to maintain appropriate brain health without fish? What is it in fish that this is referring to? And if we're gonna take fish off the plate,
Starting point is 01:33:01 what do we need to make sure that we're taking in that we're pushing all the right buttons? Yeah, I think that need to make sure that we're taking in that we're pushing all the right buttons? Yeah, I think that's a very important question. And you're right, fish has always been compared to consumption of meat and chicken and other animal proteins. And so it seems to be better. And the reason being it has lower saturated fat content,
Starting point is 01:33:21 which saturated fat is a major, major reason for damage for arteries in the brain and in our bodies, and especially causing inflammatory changes in the brain and insulin resistance, so on and so forth. So there's a whole cascade that has been associated with saturated fats. And from a public health perspective, there's consensus that lowering the content of saturated fat in our diet is very important for better brain health. So that's one aspect of consumption of fish, but you're right, there has been no study to show that compared to a healthy whole food plant-based diet,
Starting point is 01:33:56 fish, a diet that contains fish is better. We don't have that information as of yet. We don't have it either way. Right, we don't have it either way. We are concerned about animal proteins being a biomagnifier. You know, animals tend to retain elements that they're surrounded within their environment.
Starting point is 01:34:17 So, you know, all the lead and the mercury and other organic compounds that we're dumping into the oceans, unfortunately nowadays they get concentrated in the flesh of these marine animals. And if people consume fish, they consume those elements as well. And we believe that that could be
Starting point is 01:34:37 an important factor for brain diseases. And we think that a well-managed, whole food plant-based diet eliminates that risk. and that we can get the omega-3 fatty acids that come from marine animals with a plant-based diet if we take supplements, say, for example, at specific times during our life when our body needs it. or for example, when a woman is pregnant, or for example, when somebody's at a higher risk for developing mild cognitive impairment, supplement with omega-3 fatty acids derived from marine algae which doesn't really absorb much of those, the elements or the trace minerals could be very helpful.
Starting point is 01:35:20 So we believe that one can actually have a very good diet and healthy diet without it. The idea being that everything that you would get in a fish oil supplement, for example, you can get in an algae-based supplement. You're just getting it lower on the food chain. You're basically taking what the fish would filter through its body and supplementing it in a condensed form.
Starting point is 01:35:44 Exactly, the fish actually get the omega-3s from the marine algae. So what you hear a lot of, and I'm interested in how you're thinking about this, is that given the importance of omega-3, that there is something about plant-based omega-3s that aren't as bioavailable or aren't converted in the proper way that they are
Starting point is 01:36:09 when they're found in animal foods. Hence why you should be taking fish oil or these other things. And I know you did a whole podcast with our mutual friend, Simon Hill. You've done many podcasts with him on his wonderful plant-proof podcast. But you did like a whole episode on omega-3s.
Starting point is 01:36:24 So we're not gonna spend two hours on omega-3s, but like, I do wanna get this right. Sure, sure. Yeah, so we don't know the total picture. I mean, this is, the humility of science is to say, this is how much I know, this is what we don't know. And we hate this battles, but the absoluteness is absolutely not needed
Starting point is 01:36:47 or absolutely needed. We don't have that much. So we did the complete review, two papers, one on developing brain and omega and the aging brain. And even there, we didn't have conclusive evidence, but there are trends, especially in populations that are more vulnerable, the trends are saying repeatedly,
Starting point is 01:37:02 especially if the studies were done better and more, that there seems to be need for omega-3. Given the risk factor, although there are some people talking about prostate cancer, those studies are weak and the data is weak so far, but especially in populations that are vulnerable, the cost benefit for us,
Starting point is 01:37:19 it appears to be on the side of using it, not for everybody. I think if you're a young man or young woman in your 30s and 40s, if you wanna take supplements, that's fine. But we think that there's enough data that if you have enough chia and flaxseed and a walnut that you can do fine with it. But for a person that's pregnant,
Starting point is 01:37:36 especially going from plant-based omega-3, for developing brains where it's doubling every other week in size and numbers. And the one thing you need for brain development that can't produce is DHA and omegas. We think that's definitely needed. And for a brain that's under attack from vascular reasons, inflammatory reasons,
Starting point is 01:37:58 when it's aging, we think it's needed. The cost benefit actually speaks to it. The studies that would be there that would be conclusive have not been done, but having looked at the breadth of data with when we did this research, we think the trends speak towards benefit. And speak to this conversion issue. When we're talking about omega-3s,
Starting point is 01:38:22 we're talking about DHA, ALA, EPA. It all gets very confusing very quickly here. But the idea is that, yeah, when you're taking those in on a plant-based diet, they're not converting in the right proportions or you're losing out on some bioavailability here and it just doesn't work out. First of all, I think we, I've never heard this,
Starting point is 01:38:42 but I thought about it the other day. I was like, wait a second, why are we worried so much about conversion? Do we have enough or not? For example, nothing in our body gets converted at 100%. We don't have 100% bioavailability for anything, unless you inject it into the artery, you don't have bioavailability 100% for anything.
Starting point is 01:39:02 Much of what's actually ultimately bioavailable is in the lower teens, lower 20s. I mean, you eat it, it gets consumed. A lot of it just gets thrown out with the rest of it. And then whatever is bioavailable. With ALA, the percentage varies. Some people say 5%, some people say 8%. Others say up to, it's not about what they say.
Starting point is 01:39:21 Studies show up to 12% or more, but that's plenty. If you have one or two tablespoons of chia, It's not about what they say, studies show up to 12% or more, but that's plenty. If you have one or two tablespoons of chia, which has, it's a great food, chia or flaxseed or hemp. One of the few foods where the omega-3 ratio compared to omega-6 is higher. You don't even have that in animal food. So you have much higher absorption of ALA. Now the conversion of that to EPA and DHA is slower,
Starting point is 01:39:48 but you can still get plenty. The problem is when you need more, we think that when your brain, which actually incorporates rapidly DHA, might not be getting enough with just those sources. And is there some idea that if you're beginning to experience cognitive decline, or if you're at particular risk for that,
Starting point is 01:40:10 that supplementing with omega-3s is a good idea? Yeah, I mean, the studies that were actually the strongest were in the MCIs or mild cognitive impairment. Yeah, there was even a slowing of the progression of MCI and even reversal some of the symptoms of patients who had MCI that took supplements and high doses of supplement that worked well for them. So yes, we do have evidence for that.
Starting point is 01:40:30 But we also wanna couch this by saying better studies need to be done. Right. Lack of better studies does not negate trend and risk benefit analysis, given that this is the most important, one of the most important micronutrients in the body, DHA. Well, the omega-6, omega-3 ratio thing
Starting point is 01:40:49 is super interesting because sort of, if you look back 50 years, our ratio of six to three was very different than it is now because we didn't have this proliferation of processed foods that are so high in omega-6. So now we're all taking in tons of omega-6, not enough omega-6. So now we're all taking in tons of omega-6, not enough omega-3. And so how much of our omega-3 intake or supplementation,
Starting point is 01:41:11 how much of that is to kind of calibrate that ratio versus what we need independent of omega-6? In other words, if we're eating tons of omega-6, it seems to follow that we would then need to take in more omega-3 to create that correct ratio. There's a bigger problem, which speaks to why we have to go whole plant-based. So if you're eating omega-6,
Starting point is 01:41:35 the pathway of conversion of DHA EPA is actually a great limiting step. So if you're having more omega-6s, you actually convert the omega, you can't get enough DHA conversion. So one of the things you have to do is reduce the omega-6 conversion as well, because the same enzyme that actually does the conversion
Starting point is 01:41:56 is limited by both of them. If you have more omega-6, it stops, it becomes the rate limiting step. Of conversion of ALA to DHA. Correct, so it's critical that not just to increase omega-3s, ALA and others, but also reduce omega-6 resources. And what are those sources?
Starting point is 01:42:13 All the foods that have increased in the last, actually 70, 80 years, which are the processed meats and cheeses and butters and actually all processed foods that are out there have profound amounts of, we're talking about some foods have 4,000 to 8,000 as much omega-6 to omega-3. We weren't like that. So you'll never be able to correct that ratio.
Starting point is 01:42:36 The only way is to eliminate those foods and by going whole food plant-based, you're getting rid of a lot of those nasty omega-6s that you don't want. And the benefit is exponential. You're reducing the harm fast, rapidly, and this rate limiting inflammatory. So let's talk about omega-6, omega-3 quickly.
Starting point is 01:42:55 So these are not unnatural pathways. Your body needs omega-6, your body needs omega-3. One, and of course that's simplification, but omega-6 is the pro-inflammatory, pro-coagulation pathway. You need clotting and you need inflammation. And omega-3 is the opposite. As it happens that as we get older,
Starting point is 01:43:17 we need more anti-inflammatory because there becomes a chronic process of inflammation, which we have to counter. And actually baseline higher than normal. And the fact that our diets have changed. So now we have much more pro-inflammatory procoagulation. That's why we have more strokes. That's why we have more inflammatory diseases,
Starting point is 01:43:35 including autoimmune diseases. So if you don't lower the inflammatory pathway, you can pump this up. It doesn't matter. First of all, it won't go through. It doesn't matter. Right. All right, let me throw this one at you.
Starting point is 01:43:48 The brain is made up of fat. It thus needs lots of fat in the diet, saturated fat, and also cholesterol. That drives me crazy. I hear this one a lot. So walk us through this one. That drives me crazy. But I think if you look at the structure of the brain,
Starting point is 01:44:08 yes, the brain is made out of a lot of fat. The numbers vary. They say, you know, 60%, 70% fat, but that calculation doesn't really separate the amount of fluids that are in the brain too. So it's actually less than 60%, but we'll leave that alone. The important thing to remember is that fats actually don't cross, big molecules of fat, like cholesterol and saturated fats, they actually can't cross through the blood-brain barrier,
Starting point is 01:44:38 which are these tight junctions between cells in the endothelium of the cells that allow specific things to go in and specific things to come out. So the fat that is in the brain is structural fat. The only fats that are needed by the fat on a daily basis, by the brain on a daily basis are omega-3 fatty acids. And those are small enough to actually go be used. And that's basically it. The rest is just structural fat and it's maintained by all the other micronutrients
Starting point is 01:45:12 and by all the other food elements that we consume. So we don't need cholesterol for our brain to maintain its function at all. Even under the worst circumstances, your liver and your body makes enough of the rest of the fat for the brain if it needs it. Agreed. It's not a problem and the brain as well.
Starting point is 01:45:27 Any access actually just gets metabolized or they sit on your arteries and they start the process of just plaque formation, unfortunately. So nothing to that one. No, not at all. Right, and talk about saturated fat more broadly in terms of brain health.
Starting point is 01:45:43 I mean, we are, look, there are these crazy diet wars going on right now. Everybody's, you know, planting their flag in various corners of the internet. We've got the carnivores and we've got the keto people. And, you know, you will, I see this all the time. Like keto people will say, you know, I adopted a ketogenic diet.
Starting point is 01:46:01 I can focus better. My brain is working better. I'm able to work longer in a more productive way than I was able to previously, of course that's anecdotal, but there's a lot of people who feel pretty strongly about this. So speak to this a little bit. I think that they do feel more focused and I believe them.
Starting point is 01:46:22 I think that short-term, they actually do better cognitively, not better than any other diet, but they do better than what their baseline would have been. And that's why, but long-term, there's no data. I mean, if you look at ketogenic diet data, there's nothing more than six months, nothing meaningful longer than six months.
Starting point is 01:46:41 Ketogenic diet came from our field, neurology, where children with a particular type of seizure, which were not controlled by multiple medications, they were put in a shock state to control seizures. Why would we think that that's representative of a brain that's not undergoing shock? They're changing the acidic state of the brain so that the seizure is stopped.
Starting point is 01:47:08 That's not representative. And then the other thing is, how long can you maintain that under normal circumstances? These children were kept in special wards or with special diets, maintaining a ketogenic diet, a true ketogenic diet. And I can tell you- It's a lot harder than maintaining
Starting point is 01:47:26 a whole food plant-based diet. It's crazy difficult. Most of the people that said they say that they're on a ketogenic diet, they've never achieved keto ketosis. They're just eating more meat. And that they call that ketogenic diet. It's much harder than that.
Starting point is 01:47:42 So, short term, they do better. They do very well with glucose and insulin resistance. They do well as far as focus and they even do some better with certain cognitive testing, which has been done short-term. But nothing has been shown long-term.
Starting point is 01:47:57 There are no populations that have lived this life that can give you long-term benefit. The one population, which has these seizure patients have had many multiple medical problems, side effects as a result of it. So we are open, we're absolutely open because there are plant-based versions of ketogenic diet. So we're open to see if long-term anybody can show evidence,
Starting point is 01:48:19 but nothing so far. Right, but the brain runs on glucose. Brain runs on glucose. And so on a ketogenic diet, you're depriving it of glucose and it's being forced to run on ketones. Correct. Correct. So is there some scientific sensibility
Starting point is 01:48:35 of how the brain functions on ketones versus glucose? Well, the analogy, you wanna tell them the analogy? Go ahead, you tell your analogy. I'll let you tell this. I'll do the nicer part. I call a ketogenic diet as of now, it might be pejorative, but almost like a cheating on your wife kind of a thing.
Starting point is 01:48:57 So, how dare you? I know, I mean, terrible. But so glucose is the main molecule that cell requires. Preferred fuel. Preferred fuel. We did a study in Hanes, one of the largest databases, looking at even insulin resistance, not the diabetics. We took them out and looked at insulin,
Starting point is 01:49:17 they had lower cognitive state. So insulin resistance is what we're looking at. If you have too much glucose with food that rapidly rises glucose, what happens is the cell notices that there's too much of this. And actually the receptors go in. So the analogy I give is like somebody's coming as a suitor
Starting point is 01:49:39 for your son or daughter, and they knock at the door and there are too many people, the door just closes and comes out. But if it's accepted, if it's the right amount of glucose, the door opens, then it has to go to the father, to the mother, this is an old fashioned story. Yeah, but it's okay. And uncle and there's a huge family there
Starting point is 01:49:58 that you have to go. Glucose has to do a lot of work to ultimately get to the mitochondria. Imagine what mitochondria is. So it has a lot of work to do. Six, seven, 10 cycles of processing. First of all, it actually has to get through the blood brain barrier,
Starting point is 01:50:18 through an active transport, a lot of work. And that is designed to be like that. It's evolutionary design to go through this hard work for glucose to get into the cell and be functional because that's how it manages it long-term. Now let's look at keto bodies, ketone bodies. They're small molecules. They're cheating.
Starting point is 01:50:37 They're going right through the window and right into the mitochondria, skipping all the steps. Yeah, don't have to deal with dad. None of that stuff. Crazy uncle. Initially, a lot of energy, a lot of fun, a lot of other stuff. This analogy always goes awry.
Starting point is 01:50:51 But long-term, it's, you know, you feel... So ketone bodies might work short-term because it's a quick burst, even for the mitochondria. But where does in the biochemistry textbooks or any biochemical process, does it say that doing the quick thing in the biochemical processes is long-term benefit? From my reading and Aisha's reading
Starting point is 01:51:16 and our research in molecular pathways, there's no evidence that anything that's short-term like that is going to be beneficial long-term. Like you said, it's under a shock state. So, you know, and most of the studies that have been done on ketone bodies have been done in individuals who have had advanced Alzheimer's disease.
Starting point is 01:51:36 And at that stage, there's a lot of damage that has already been done. There's the structural damage, vascular damage. And so ketone bodies act as an alternative fuel, right? So the cells probably don't have the opportunity to use glucose as a fuel, but ketones that don't require all these steps that Dean mentioned,
Starting point is 01:51:58 you know, they don't have to go through it and they go right into the cell. And initially there may be some improvement in their cognitive skills and in their neuropsychological scores, but long-term. I think the only study that we have is a feasibility study that was less than six months. And that's basically it.
Starting point is 01:52:14 So we don't have any long-term results. And if we do, I'll be excited to actually read about it because it sounds very promising. We just don't have the data yet. Is it not an emergency state for the body? It's like a survival mechanism that evolved over millennia to keep a human being alive if they were deprived of food
Starting point is 01:52:35 for a certain period of time, right? So in that sense, your physiology is in crisis. Is there a downstream impact on your neurological functioning? Like, are you in a sort of sympathetic nervous system state of high alert when that's going on? Right. We think so.
Starting point is 01:52:59 We think, I think it's a survival state. That's why survival states are short-term states. That's why, I mean, when we talk about stress, it's a short-term beneficial state that now has become chronic. Right. We keep missing the evolutionary flaw here. We keep addressing what's short-term benefit
Starting point is 01:53:17 and think that that's long-term benefit. It's not. So we think that at least biochemically, even evidentially, I mean, we're looking at evidence from all the studies. There's no evidence at this point that this is a magical cure for dementia or Alzheimer's or any of these things. It's just as short-term survival that long-term
Starting point is 01:53:37 we think has consequences. Right, rather than climbing in the window. How about this analogy? It's sort of like pulling an all nighter and you can, you're gonna get away with the grade on the test, but a month later, you're not gonna remember anything. I can say that story much better than my story. So let's look at the foods that are beneficial.
Starting point is 01:53:58 Like when you look at the plant kingdom, what stands out? I know we wanna stay away from quote unquote superfoods, but some foods are better than others. Like what should people focus on who are trying to enhance their brain health? Yeah, I think if I had to give a quick version of what's out there as far as data is concerned,
Starting point is 01:54:22 consumption of green leafy vegetables, for example, seems to be very helpful. And it's like unanimous results that you see across different studies. Berries, such as blueberries and strawberries, they stand out, whether it's the MIND diet or the Mediterranean diet, or even in the Adventist Health Study,
Starting point is 01:54:38 because these are foods that have the highest amount of anti-inflammatories. Spices like turmeric. We actually wrote a paper when we were in Cedars-Sinai where we gave our patients high doses of turmeric and turmeric seems to have, the curcumin part of it is a very potent anti-inflammatory and it seems to bind with amyloid,
Starting point is 01:54:57 which is the bad protein associated with Alzheimer's disease and it removes it. Oh, wow. And we measured the amount of amyloid, the amyloid load in retina. And after giving them high amounts of turmeric, we actually saw the turmeric binding to the amyloid in the retina.
Starting point is 01:55:12 Just really, really interesting. And we're learning more about it as we speak. And yeah, so high fiber green leafy vegetables and berries and spices, especially turmeric seems to be on the top. Chia and flaxseed. Chia and flaxseed, which are amazing sources of plant-based omega-3 fatty acids, hemp seeds,
Starting point is 01:55:33 nuts like walnuts, whole grains. They seem to have the right kind of micronutrients, whether it's thiamine or riboflavin or folic acid bound beautifully synergistically supporting each other's absorbance and bioavailability, they all tend to reduce the risk for Alzheimer's disease. And we have studies that have looked at individual foods
Starting point is 01:55:55 and risk of Alzheimer's disease and the combination thereof too. Are there any plant foods to avoid? I would say the plant foods to avoid seems to be coconut oil. I know that that again is a controversial area and a lot of people are just, yeah. A lot of people are getting mad right now.
Starting point is 01:56:11 I know, I'm sorry. But you know, I love coconut. Well, that used to be the thing, coconut oil for brain health. Yeah, I know. And unfortunately the data was pretty flawed when it came out. It was based on a couple of case studies
Starting point is 01:56:24 and as it happened, somebody gave their loved ones some coconut oil when it came out, it was based on a couple of case studies. And as it happened, somebody gave their loved ones some coconut oil and they seemed to improve, but then there was no long-term follow-up. But coconut oil, and I'm happy to say that there's consensus on it. And as a scientist, I want to look at different sources of data, whether it's clinical trials,
Starting point is 01:56:41 whether it's epidemiological, whether it's case series, and there's consensus between different scientists and doctors and physicians that coconut oil seems to increase our bad cholesterol, LDL, which can result into vascular damage. And the reason being is because coconut oil is one of the few plant oils that is more than 90% saturated fats. And so is palm oil. plant oils that is more than 90% saturated fat. And so is palm oil. And the little nuance as the MCT, medium chain triglycerides, that has to be studied. And we're open to that.
Starting point is 01:57:13 I mean, we think that if those studies come back and show some benefit, we would be more than happy because we need anything that's out there that's gonna help. So far, no data, no tangible data. But with coconut oil, doesn't that LDL saturated fat component, isn't it fairly easily converted to like linoleic acid,
Starting point is 01:57:34 which makes it more available as an energy source as opposed to being stored? It could, but reality is that that number, so that's a mechanism. Actually that mechanism exists for a lot of saturated fats, but reality is that when the studies are done over and over again, what they see is when people consume coconut oil,
Starting point is 01:57:52 it is actually the atherogenic and inflammatory component that predominates. Interesting. It is a processed food anyway. So in the context of talking about whole food plant-based diet, it's not even really part of that conversation anyway, but you did shift gears with olive oil to some regard.
Starting point is 01:58:09 Here's talk about controversial. We were actually ostracized by some communities for this, which I'd never thought that- There's a heated debate going on. Yeah, people are very strong opinions about this. It's so funny. We worked in Afghanistan and were ostracized by Taliban. So some plant-based people ostracizing us
Starting point is 01:58:27 doesn't scare us too much, but yeah. So please ostracize us away. They're not as well armed. Not as well armed and so much lovelier people anyway. So the reality is we're open to data. It's not about dogma. There are a couple of lines of argument and it's not always because we looked at Mediterranean diet.
Starting point is 01:58:45 We're actually in the middle of doing a meta analysis. The data is again, trend. And nutrition data is tough. So you have to go with trends and multiple domains of trends. And it appears that some, and here's another controversial term, some, olive oil seems to help with cognition,
Starting point is 01:59:05 seems to help with health in general, and specifically, extra virgin olive oil. And then the quantity is controversial, how much we think that there is a point of excess. So we say use as minimal as possible just to help with both digestion and with food. But we just wanted to open up the realm, even though we might make people angry, that's okay.
Starting point is 01:59:28 That's our life. But if it's data shows this way, we got to start talking about it. And at the same time, when we go to these churches and faith communities, which another one of our projects is a women-centered faith-based community, brain initiative in African-American churches.
Starting point is 01:59:50 Disproportionately impacted by Alzheimer's. And also more importantly, as Aisha has finished getting her PhD in women's leadership, focusing on women in health is the most effective money spent in health. So if you're going to change, bring a brain health initiative, it should be around women. So especially African-American women
Starting point is 02:00:10 or black women and their communities. But we see, and if we go to these communities and Hispanic communities and other communities in Appalachia or Pittsburgh, where I come from and say, no meat, no cheese, no butter, no salt, no sugar, no fat, no oil, no butter, no salt, no sugar, no fat, no oil, no Dean. Right. So you're gonna have a little bit of an adherence problem.
Starting point is 02:00:32 Absolutely. Now that doesn't speak to the science. And I spoke already to the science that there seems to be some trend that that's positive. Olive oil is fine, especially cardiovascular data. But it does speak also to compliance. And since we work in the communities and we're not doing contrived 100% studies in a lab,
Starting point is 02:00:52 we think that's as important. Well, compliance is everything. If you don't have compliance, it doesn't matter. Exactly. But you have to be careful, right? Because you don't wanna veer too far towards compliance. Then you're the practitioner who's like, I'm not gonna tell them about livestock
Starting point is 02:01:07 because they're not gonna do it. Exactly, exactly. It's a balancing act. So we say what's the optimal, especially people who have, so complexity is, you know, somebody said, I think somebody we know said that the entire problem we have in this world is, I think Dr. Katz,
Starting point is 02:01:24 is about people not being comfortable with complexity. There's a complexity in this. And the complexity is we have to worry about adherence, but at the same time, we have to say what the truth is. And here's another layer of complexity. If somebody has a four vessel disease, we say go all the way, no fat, because the data is there, that if you have four vessel arterial disease, you might as well go all the way as opposed fat, because the data is there, that if you have four vessel arterial disease,
Starting point is 02:01:45 you might as well go all the way as opposed to, you know, so there's a bit of complexity there. Right, yeah, people don't like that. I know, I know. It's hard, the truth will set you free. You have to be able to make room for nuance now more than ever, things are so crazy out there. And the only way to do that is to have,
Starting point is 02:02:06 you know, conversations like this, it's not gonna happen on Twitter and it's tricky. And it's people's identities are wrapped up in these ideas. And people don't like to be challenged with that because it threatens, like, it's almost like cognitive decline. Like my sense of who I am is being pulled out from underneath me. And emotionally, it's very difficult.
Starting point is 02:02:27 Right. You are a controversial, one of the people we admire greatly, we're not gonna name names, don't worry, actually said they would not endorse our book, even though we are in the communities by the thousands, helping thousands of people with a whole food plant-based diet,
Starting point is 02:02:44 just because we say add a little bit of olive oil. Yeah, everything gets more and more specialized. It used to just be vegetarianism and then it's a vegan and vegetarianism. And then within those categories, there's more and more silos until there's just one person left and each one of them is on silos.
Starting point is 02:03:05 And nobody can talk. Everybody's got their own newsfeed, you know, and we can't communicate with each other anymore. I mean, that's where this is headed. It is, it is. It's sad, it's sad. Aisha, how many PhDs do you need? No, I'm just, I feel so lucky.
Starting point is 02:03:21 Well, first of all, I have this amazing partner that, you know that just allows me to experience life in its fullest. And so I have a master's in clinical research and I went to medical school and I've worked in clinics and I got a fellowship in vascular neurology. But the more I am in this field, I realized that if we don't focus on the human component, it's meaningless, meaningless.
Starting point is 02:03:59 And having had the privilege of working in the communities, meaning going there, sitting down with them, listening to them, working in the community clinic where you have these lovely people coming in and telling you like, doc, I know this is important. I just can't do it right now. I just can't do it because of this, this, this, this. to a woman who has two jobs, is divorced, has four or five children to take care of, has a parent with dementia that she takes care of, has tremendous amount of stress because of the situation in the world,
Starting point is 02:04:36 and tell them, you know, just meditate every day. Meditation is really good for your brain. That is such an elitist statement. That is such a flawed approach to health. And so what do you do to make yourself available? And what do you do to create an environment in their communities where they can have access to health and wellness in their comfort zones?
Starting point is 02:05:01 And so having worked with different individuals and especially in the faith-based communities, the one thing Dean and I have noticed, and this actually comes from our work in Afghanistan as well, where we've noticed that if we invest in the women in those communities, you've actually invested in the families and in the communities
Starting point is 02:05:23 because the women's are the best representatives of that unit in the community. And when you look at different models of success in the world, one of them that came from Dr. Yunus, who was the Nobel Peace Prize laureate. He's the father of microcredits where he essentially helped women and their small businesses. And he made some profound statement. He said, when you help women, you actually help families and you help change that society because no disrespect to men, I love you guys, but women know how to invest in their families and in their units. And so I'm pursuing this PhD in women's leadership because we believe that if women are ambassadors of brain health and mental health, I think it's a game changer. And we've seen that. We've seen that in Afghanistan and Dean doesn't talk about that, but one of the things that is such a profound
Starting point is 02:06:26 story in our life was when, I'm going to say that story for you, when he was working for the World Bank, he was in Afghanistan and he was running the Ministry of Health. And one of the challenges was to make health available for all these provinces and villages that were away from the capital. And there are not a lot of hospitals there. I think we learned more about public health there than any course at Columbia, that any course at NIH and UCSD and Loma Linda University combined together.
Starting point is 02:07:02 So knowing the politics and the bureaucracy, what Dean did was essentially a social jujitsu where he trained, he created the establishment to train 20,000 girls who were, you know, went to school up to a sixth grade because after that, usually there's no education available for girls in the provinces. And so he took sixth grade educated girls and he wanted to train them in just basic healthcare. How to give ampicillin when somebody has upper respiratory infection, how to create oral rehydration solution, which is one liter of boiling water, one fist of sugar and a pinch of salt, because one in five is it? Children under the age of five die from easily preventable diarrhea in those countries. And to give them that oral dehydration solution, you've actually saved a
Starting point is 02:07:57 life. Or to tell the difference between spotting and bleeding in a pregnant woman, because the hospital, right, is about five days on a donkey ride, right? So just basic things. And so there was a lot of pushback initially about this project. They said, nope, you're not going to take our girls and educate them. This is against our faith,
Starting point is 02:08:17 against our culture and tradition. And Dean said, no, no, no, no. This is going to be done in your communities and in your villages. And so they accepted it. And that was a beautiful move because they created mud huts, clinics for these girls in a very prominent place with a flag on it. And it was just a very basic place with a chair and a table and maybe a bed sheet as a curtain with a small little bed for the midwife or the nurses, nurses and midwifery program to examine patients.
Starting point is 02:08:55 And guess who would get sick after a few days? The men would get sick too, right? And there would be that girl and she would be the community doctor. And suddenly you've completely flipped the relationships. That just fucks up their whole mindset of the whole thing. So the jujitsu here is you don't have to confront cultural paradigms, you jujitsu around it.
Starting point is 02:09:19 And when most of healthcare, thank you so much for telling that story. That's amazing by the way, like incredible. We wrote a paper together. Yeah, it's actually in Lancet. Oh wow. How to apply it to other communities. And if we do that, not so much jujitsu,
Starting point is 02:09:33 but use the resources of the community to build this paradigm around women. I mean, your wife, the power we know. What a human she is. And also they're the leaders. And even in those Taliban infested places, yeah, they do all the yelling and jumping around, the men do, but who runs the households?
Starting point is 02:09:56 Right, they're making the decisions about- They're making decisions. What people are doing, what they're eating. Women are the leaders. Women are actually the leaders. And we can build a whole healthcare system, brain health initiative around women. So that's been our work for the last two and a half years. Yeah, so applying that template,
Starting point is 02:10:11 here in the United States, going into these communities, trying to pull some, tweaked version of that jujitsu maneuver to empower these women and list them in this cause and in turn, have them help create structures that trickle down into their families. Right, absolutely. Yeah, so that's the goal.
Starting point is 02:10:32 And it's been an amazing journey just experiencing that firsthand to see how wonderful of a communicator a woman can be and how easy it is for others to listen to a woman who is a sister, a mother, an individual in the community coming from a very empathic and a loving place, but at the same time from a very powerful place. I'm just so excited to be in that area.
Starting point is 02:11:00 There's no bounds to the upside of that, I think. That's right. Well, let's talk about the new book. I mean, you guys wrote this amazing book, the Alzheimer's solution that came out a couple of years ago. That's what brought you onto the show back then, which is basically an incredible primer on all the research that you've done, case studies,
Starting point is 02:11:23 your work with your patients in terms of implementing lifestyle interference to interrupt this brain dementia issue that is mushroom clouding in our society. But the new book, the 30 day Alzheimer's solution, right? Is more of a tactile, like very easy to use guide for how to kind of, you know, implement these tools in your daily life using this neuro paradigm of, it's basically mostly nutrition focused.
Starting point is 02:11:54 You talk about the other stuff, but it takes you through a program. It gives you kind of tools for how to make these changes in your life. And then you have all of these beautiful recipes to try to make it as appealing and delicious and easy for people to do as possible. So it's great.
Starting point is 02:12:13 I love it. My only complaint is that it was a digital version and I don't have the book yet, but it's coming out soon. So talk a little bit about why you decided to write this book and what your plan for it is. Thanks, Rich. That's very kind of you. And we'll definitely get you a copy.
Starting point is 02:12:30 I think the pandemic slowed down everything, but we're very proud of it. It was difficult to put our experiences in a way where it's translational and palatable part of the pun, in a way where it's translational and palatable part of the pun. But we wanted to focus in on the how part of brain health. The first book was essentially the why and a lot of signs, but the applicability part has been expanded in this book. And the title, The 30 Day, was a little uncomfortable initially. What does that even mean? Does it mean that in 30 days, I'm going to have the best brain? No, but I think it's a 30 day journey or a plan towards that direction. And
Starting point is 02:13:10 we're just really excited. And I think one of the reasons I went to cooking school after going to fellowship was just because of the passion that I have for application of all the science and knowledge that we have already. One of the key things in behavior change is process. A lot of times people get focused on goals and goals fail us because once you reach, as I said, you feel anticlimactic and then what? It's process that's important. Systems have to be established. So the 30 days is attempting, and I never want to do hyperbole, and is attempting to create an environment for systems. In fact, with the book, for those who sign up early,
Starting point is 02:13:54 this is a marketing tool, but they get a- You get all kinds of bells and whistles. My goodness, I never thought that at NIH I would be doing this stuff, but in any case. You've turned into a marketer. But nonetheless, but it is actually, I think it's helpful we are giving people, by the way, we said, if you buy the book early,
Starting point is 02:14:17 you get access, but it's actually honor system. You don't have to buy the book. You can get access to a 30 day course that starts at the 1st of April up to the end, where we have sleep doctors, stress doctors, nutritionists, lots of data and equipment and cooking sessions and courses, where Aisha does for free, by the way, takes them with the book through this process for a month,
Starting point is 02:14:40 not with the hopes that at the end they come out completely different, for a month, not with the hopes that at the end, they come out completely different, but for them to be familiar with possibilities of where the changes, the micro changes can take place. You've spoken to an amazing, the atomic habits. James Clear. James Clear. I love the book. Great conversation. I mean, I've read a lot of books.
Starting point is 02:15:01 It's those little incremental successes that change into habits, which change into then culture. So this month is about going through this process with brain and mind, sorry, that there's another one that came out, that actually takes them through. And hopefully by the end of it, they have enough of these little micro habits
Starting point is 02:15:22 that becomes a process individualized and habits. Yeah, I like how you broke it all down and you didn't sugarcoat it either. You're like, look, this is gonna be hard. If you're gonna get off cheese, it's gonna be uncomfortable. Like you're not trying to say it's all gonna be awesome all the time.
Starting point is 02:15:37 Like it's, you know, making any kind of change is difficult and this is no different, but what you find on the other side is worth it. And you give the right amount of like encouragement and you couch motivation in the right context. And I appreciated that as well. But you paint with a broad brush so that, you know, anybody could pick this up and, you know,
Starting point is 02:16:00 get their head around what the right path is. That was the goal. That was the goal for, and we basically wrote this for our caregivers and the patients and everybody that's been touched by Alzheimer's. And I know the cover says Alzheimer's, but it's essentially brain health in general
Starting point is 02:16:16 and cognitive decline, which a lot more people are experiencing. Yeah, I mean, it's really hard to appeal to a young person to make changes in their life because they might get Alzheimer's. Like that's, talk about a motivation problem. Yeah. But if you instead rephrase it as cognitive enhancement
Starting point is 02:16:34 or some sort of brain hack or something like that, then suddenly you get young people's attention. Absolutely. You get them interested in taking care of their brains so that they don't fall prey to this later in life. Absolutely, yeah. I think it's important to say it that way. And for us, we have the Healthy Minds Initiative,
Starting point is 02:16:53 which is a non-for-profit where our goal is hopefully that we can promulgate and spread this concept of coaching, women-centered coaching throughout the country. And whatever comes out of this book goes towards that effort. of coaching, women-centered coaching throughout the country. And whatever comes out of this book goes towards that effort. Whoever wants to help us out goes towards that effort. And I think it's a worthwhile endeavor with Aisha and the lead and I'm the driver.
Starting point is 02:17:17 Right. We're a team. Wow, so all proceeds from the book go to the nonprofit. All of it, fantastic. All the profits. Yeah, and that nonprofit Healthy Minds Initiative is very involved in what you're doing in Redondo, where you live right now, but the idea much like Blue Zones is to kind of scale this
Starting point is 02:17:36 for and model it for other cities and communities. Absolutely. Yeah, that's right. The Beach Cities Health District is where our flagship Healthy Minds Initiative study is going on. We have one in Arizona, in South Carolina, and we're expanding it in other states as well. And we're basically training coaches
Starting point is 02:17:56 who can be brain health representatives and ambassadors in their community and just move it forward. Right, awesome. Well, we gotta land this plane, but I got two more things I wanna ask you before I let you go. The first is, obviously there's so much more research
Starting point is 02:18:11 that needs to get done in terms of brain health and also nutrition and how lifestyle impacts brain health. What is, if you had your druthers, like what is the study that you would set up? Like what is the big study that's missing right now? Like forget about cost, just how would you do it? What would it look at? First of all, it'd be a little longer term.
Starting point is 02:18:34 It would be at least three to five years and it would actually have imaging and it would be community-based. That seems contradictory like this technology but it would be community-based. That seems contradictory, like this technology, but it would be community-based because just like mouse models that work, 400 mouse models for Alzheimer's worked, zero worked on humans.
Starting point is 02:18:55 The same way these little contrived 100%, 200% studies on six months, seven months means nothing. If we don't do it in larger populations and we don't get good markers of cognition, which is neuropsychological testing, biomarkers and imaging that shows this change over time, it's meaningless because you will get, every diet will come up with a paper saying,
Starting point is 02:19:17 look at my study, six months, look at my study. There'll be many of them, documentaries and everything put together, but we need a larger study for going forward. So we're doing the data capture in our national, we'll take care of the funding there. We don't have the funding for imaging. We don't have the funding for blood tests
Starting point is 02:19:33 and the regular funding sources don't seem to get it. They're not adjusting saying, look, we'll take care of the educational component. We'll take care of the resources, the technology. We'll take care of all of that, We'll take care of the resources, the technology. We'll take care of all of that. But we need some help with the biomarkers and imaging component, and we can have the best study for cognition.
Starting point is 02:19:53 And then we will have studies that we'll look at because it's a large population. We'll know data on ketogenic. We'll know data on plant-based whole food. We will know data on omnivore or even pescetarian. That would be the optimal study that would be out there. So essentially a massive population study, community-based study of where people
Starting point is 02:20:14 would be self-reporting or? We have the methods of collecting data and not on a once a year basis where the food frequency questions are, but actually on a monthly or weekly basis, we have the tools now. We actually using that in beach cities, using iPads and computers,
Starting point is 02:20:29 we can collect the data on as far as that's concerned. We have the tools as far as collecting sophisticated, cognitive information on the computers, and we'll take care of all of that. So those two big components, and as far as teaching them using Zoom, for us Zoom was now actually yesterday, we had a Zoom session with our teaching population
Starting point is 02:20:48 of over a hundred people. So that's even taken care of. We'll take care of the education component on a weekly basis and the coaching training. The only thing that's needed is that biomarker funding that would really help us out because there's bigger costs we've taken care of. Okay, last question.
Starting point is 02:21:05 I can't remember whether I asked you guys this last time you were here. If I did, I'm gonna ask you again. I don't remember what you said anyway. If you woke up tomorrow and realized you'd been appointed as surgeon general of the United States and given the kind of metastasizing Alzheimer's problem like this, you know, apocalyptic number of people,
Starting point is 02:21:31 you know, tripling by 2050, you know, what kind of policies would you try to implement or legislative changes would you be thinking about that could move us in the right direction as a nation? Ooh, that's a tough one. You wanna go first? Okay. Well, I would say more resources for communities
Starting point is 02:21:57 about managing their lifestyle. I think most of the funding goes into very specific molecular datas. I think less is being focused on individuals in the communities. And that's where I would focus, whether it's changing lifestyle with behavior models, whether it's nutrition education, whether it's exercise education and fitting it according to their resources, that would be the place to focus on. I fully agree. Yeah.
Starting point is 02:22:30 I mean, we were talking about, we talked about mind diet at one point, which is not an optimal diet. Even the people, the main PI passed away recently. Martha Morris. Martha Morris. Even she said it's not the optimal diet, but yet 53% reduction in Alzheimer's.
Starting point is 02:22:47 And I'm sure that the same number would apply if not more for stroke and everything with this mind diet. So why wouldn't we invest at all in this kind of an approach and especially in the community-based model? So I fully agree with Ayesha, that would be the investment. Yeah, it seems like more local based medicine, an overhaul of healthcare to re, you know, sort of reconfigure it around prevention,
Starting point is 02:23:15 as opposed to diagnosis and prescribing people. Absolutely. But yeah, we need a lot of changes, don't we? We do. But you guys are playing a huge role in reversing this tide. And I really appreciate the work that you're doing. You're truly saving lives and it's admirable.
Starting point is 02:23:34 And I wish you all the best. It's amazing what you guys are doing. Thank you. Thank you for helping us disperse the message. I mean, this is truly important. Anything to help you guys out anytime, reach out. Thank you, that was amazing. Appreciate you guys.
Starting point is 02:23:48 Appreciate you. The new book is called the 30-Day Alzheimer's Solution. It's available March 23rd. Correct. That's pub date, right? Yes, it is. Practical guide to help you wrap your head around everything that we talked about today and more importantly,
Starting point is 02:24:03 implement those changes into your life. If you wanna dive deep into the science and geek out on all of that, I would highly recommend picking up the Alzheimer's Solution, their first book. It's amazing. You can find these guys at Team Shurzai on the internets. That's right. And anything else, anywhere else to point people?
Starting point is 02:24:21 Is there a website for your nonprofit if people wanna learn more about that? Healthymindsinitiative.org, yes? Healthymindsinitiative.org. Yes, healthymindsinitiative.org. And they can contact us. And if they're interested in volunteering or having us come to their communities, we would be happy to do that.
Starting point is 02:24:33 Awesome. All right. And you guys are welcome here anytime. Thank you. Come back and talk to me again, okay? Thank you so much. Thank you. Peace.
