Starting point is 00:00:00 Coming up next on Passion Strike. In these countries, our most common and major diseases were universally rare, like heart disease. In the African population of Uganda, for example, coronary artery disease was almost non-existent. If you look at age-matched heart attack rates in Uganda versus St. Louis, out of 632 autopsies in Uganda, one myocardial infarction, and it was evidence of a healed myocardial infarction, so it wasn't even the cause of death.
Starting point is 00:00:24 Yet out of 632 autopsies in Missouri, same age and gender distribution, 136 myocardial infarctions, so 100 times the rate of our leading killer. In fact, they were so blown away, went back to another 800 autopsies, you got an instilled just at one small healed infarct. Out of 1,427 patients, less than one in a thousand, whereas here in the United States, heart disease is an epidemic. Welcome to Passion Struck. Hi, I'm your host, John R. Miles.

Get ready to be inspired, informed, and energized as we learn from the Master Himself. Thank you for choosing PassionStruck and choosing me to be your host and guide on your journey to
Starting point is 00:04:39 creating an intentional life. Now, let that journey begin. intentional life now, let that journey begin. I am absolutely honored and thrilled to have the one and only Dr. Michael Greger on passion struck. So excited to be here. Dr. Greger, we all have moments. I think that define us at defining moment for you was your personal experience with your grandmother's remarkable
Starting point is 00:05:05 recovery from age end-stage heart disease. Can you share with us a little bit about how her transformation influenced your perspective on the power of lifestyle and interventions and promoting health and longevity? Absolutely, yeah. That's how it all started with my grandma. I was just a kid. When my grandma was sent home, basically in a wheelchair to die, she had this end-stage heart disease, so many bypass surgeries,
Starting point is 00:05:32 she basically ran out of plumbing at some point, confined to a wheelchair, crushing chest pain. Her life was over at age 65. Then she heard about this guy, Nathan Pritikin, one of our early lifestyle medicine pioneers. And what happened next is detailed in Pritikin's biography. He talks about Frances Greger, my grandmother. They wheeled her in, and she walked out.
Starting point is 00:05:52 Though she was given a medical death since at age 65, thanks to a healthy diet. Was able to enjoy another 31 years on this planet, till age 96, to continue to enjoy her six grandkids, including me. That's why I went into medicine. That's why I went into medicine. That's why I went into lifestyle medicine, why I started this website, NutritionFacts.org, why I wrote the book, How Not to Die,
Starting point is 00:06:12 why all the proceeds from all my books are all donated directly to charity. I just want to do for everyone's family what Pritikin did for my family. I'm going to speak to this a little bit, because on this show, I have had a ton of medical professionals and a notable observation that surfaced regarding all of them is that when they go to medical school, there's a limited
Starting point is 00:06:36 emphasis that's placed on nutrition in traditional Western medicine, considering your background as a conventionally trained physician, what prompted your shift to focus on nutrition? Yeah, I mean doctors have a severe nutrition deficiency in education. Most doctors are just never taught about the impact healthy nutrition can have on the course of illness, so they graduate without this powerful tool in their medical toolbox. Of course, there's also institutional barriers, time constraints,
Starting point is 00:07:05 lack of reimbursement. Generally, doctors simply aren't paid for counseling people on how to take better care of themselves. Of course, look, drug companies also play a role in influencing medical education and practice. You can ask your doctor when the last time they were taken out to dinner by Big Broccoli. It had probably been a while, but from my personal story,
Starting point is 00:07:24 I had seen it with my own eyes, and so I knew the power of lifestyle. And then 1990, the publication of Dr. Dean Ornish's Lifestyle Heart Trial proved it to the world, published in the most prestigious medical journal in the world, showed for the first time that you can open up arteries without drugs, without surgery, just a plant-based diet and lifestyle program. Proved it with something called quantitative angiography. You can actually see the arteries opening up.
Starting point is 00:07:49 We thought heart disease was irreversible. You just got worse than you died, but first Nathan Pridikin showed that you could reverse heart disease, but he didn't have the proof in black and white. We didn't have that angiography technology, but then Ornish actually proved it. And look, this was 1990, so decades ago, we proved that the number one killer of men and women can be prevented, arrested, and reversed with a plant-based diet, yet hundreds of thousands of people continue to die from this preventable, arrestable, reversible condition.
Starting point is 00:08:21 That's why I went into nutrition. Well, thank you for sharing that. And you have created some incredible bestselling books. You mentioned how not to die, how not to diet. I wanted to ask you some questions about those before we go into your latest masterpiece, how not to age. I think the biggest question I want to ask is if someone is here on the podcast today and they're dealing with cancer or some type of illness like that,
Starting point is 00:08:51 what would be some of the most profound things that they could do right now if they wanted to positively intervene in stopping its growth? Well, first of all, the good news is that we have tremendous power over our health, destiny, and longevity, and that the vast majority of premature death and disability is preventable with a healthy enough diet and lifestyle. In terms of the single most important thing we could do, it's really tweaking our diet.
Starting point is 00:09:20 According to the Global Burden of Disease Study, the largest systematic analysis of risk factors in human history found that the number one cause of death here in the United States is the American diet, bumping tobacco, smoking to number two. Cigarettes not only kill about a half million Americans every year, whereas our diet kills many more. But that's good news, because the power is then at the end of our fork.
Starting point is 00:09:47 OK, and if one of the types of cancers that is really increasing right now is pancreatic cancer, and it's soon to become number two on the list of taking the most lives from cancer, do you have any insights into what is causing this rise with pancreatic cancer and specifically what you would do to someone who might be diagnosed with this with diet intervention? Yeah, pancreatic cancer is one of our most lethal cancers, though it would be hard to imagine it kind of bumping out killer number one lung cancer and then cancer killer number two colorectal cancer, which really kind of far lead the field. But I do have some—so if you go to nutritionfacts.org, I do have some videos talking about improving survival with pancreatic cancer,
Starting point is 00:10:37 with certain dietary interventions. However, by improving survival, we're talking about extending, compared to the control group, life by a matter of months, not years. But still, that may be better than some of the kind of chemotherapy regimens we now have on the market, which may not improve quality of life or survival at all. Okay. Well, thank you for that. In How Not to Age, you ventured into the realm of aging, and there've been a number of books over the past year
Starting point is 00:11:07 that have come out that have talked about longevity. There's been Lifespan, there's been Dr. Mark Hyman's book, Peter Atay's, Kara Fitzgerald's. What sets How Not to Age apart from those other books and your previous works? Well, I really wanted it to be the most comprehensive anti-aging book ever published covering every possible strategy for slowing the aging process for the longest, healthiest life, based on the best
Starting point is 00:11:34 available balance of evidence. And so, I ended up with 13,000 citations. It took me three years. We have a team of 22 people working on it, churning through tens of thousands of papers. So I really wanted it to really cover all the bases, really be kind of the reference book for this. I don't think any other resources really come close to the kind of comprehensive nature.
Starting point is 00:11:56 So whether you're interested in targeting some of the aging pathways to actually slow the aging process, or just talk about preserving function, whether we're talking about bones, bowels, bladder circulation, hearing, hormone balance, immune function, joint health, mind or muscle, sex, life and skin, teeth, vision, etc. So some of the more kind of cosmetic areas, you're just worried about your skin, or if you're worried about some of these more critical issues in terms of preventing, arresting, reversing chronic disease.
Starting point is 00:12:24 And so I really wanted to just cover everything. I don't think any other book has quite done that yet. Okay. And I just want to set this up for the audience because it's going to be impossible for me to go through nearly everything in your book, because when you originally wrote this, I think it was like 20,000 words and you got it to then down to 10,000 words and or I probably have the statistics wrong. Order of magnitude off. But my point is this is a very
Starting point is 00:12:54 comprehensive book and it's now about 600 pages and it has some really incredible information in addition to what's in the book that the reader can go through and link out to as well. But the book is divided into four sections. Slow 11 pathways of aging is the first section. The second section is the optimal aging regimen. Third is preserving function. And fourth is your anti-aging eight. So I'm going to approach this interview by kind of going through that pattern.
Starting point is 00:13:26 And I'm gonna open it up with this question. Dr. Greger, there's a growing trend of older Americans, and I think people in many Western civilizations, where they're seeking out anti-aging interventions with a significant portion of them investing in products and treatments that are touted by the industry. However, many of these interventions lack scientific backing. Can you share your perspective on this phenomenon and offer any guidance on how a person might navigate this landscape?
Starting point is 00:13:59 Yeah, no, and that's really why I wrote this book is really to cut through all that noise and nonsense. It reminded me of my last book on weight loss, on how not to diet. Both dieting and anti-aging are these multi-billion dollar industries, and with so much money in the mix, anyone seeking even basic, practical advice in either arena, living lighter or longer, is faced with the just inscrutable barrage of pills and potions. I mean, even as a physician with the luxury of wading neck-deep through the medical literature, it's really been a challenge
Starting point is 00:14:33 to tease out facts from farce. And look, if it took me three years to sift through all the signs, I'm afraid the casual observer would just have kind of no chance. But the more difficult it was, the more valuable I realized this resource will eventually be. Well, thank you for that background. And one of the things I wanted to ask you about is, I think there's this notion we often hear about,
Starting point is 00:14:56 I certainly have heard it throughout my whole life, that people want to end up dying from old age or that person died from old age. However, this concept of dying from old age or that person died from old age. However, this concept of dying from old age may not be accurate as centarians and others typically succumb to specific diseases rather than old age itself. What role do you believe that aging plays as the primary risk factor for the conditions many people face?
Starting point is 00:15:27 Based on a study of 42,000 consecutive autopsies, centenarians, those who live over 100, were found to succumb to disease in 100% of cases, though most were perceived, even by their physicians, to have been healthy prior to death. Not one quote-unquote died of old age. They died from disease, most commonly heart disease, and are one killer of men and women in general,
Starting point is 00:15:49 which is again great news because there's diet and lifestyle interventions that can prevent arrest and reverse it. So that's kind of a critical point to remember, though aging is a primary risk factor for many of our leading killers. So, for example, yes, having a high cholesterol can make you 20 times more likely to have a heart attack compared to some low cholesterol. A 80-year-old has 500 times the risk of having a heart attack
Starting point is 00:16:21 compared to a 20-year-old. Now, the reason we talk about cholesterol is because it's a modifiable risk factor, but the question I raise in the book is what if aging was modifiable too? And then we could slow down the rate of kind of age-related diseases across the board. So, for example, even if all cancer was eliminated tomorrow, the average life expectancy in the United States would only go up three years. Why? Because if you don't die from one age-related disease, you just die from another. The only reason you didn't die of a heart attack
Starting point is 00:16:55 is because you were killed by cancer, but you were getting ready to die next month from a heart disease anyway. So, instead of playing whack-a-mole by targeting each of these diseases, by slowing aging, we can reduce the risk of heart disease, cancer, stroke, dementia, all these age-related diseases in one fail swoop. I love that approach and how you can deal with all of it, because it's interesting. I have seen statistics where as much as two-thirds of the population has one, if not two underlying conditions by the time most of us reach our fifties, which means that really 30 to 50% of your life, however you want to look at it, you're
Starting point is 00:17:40 dealing with a chronic illness, which to me is sad and it's preventable. What is the most important thing a listener could do today if they wanted to change that perspective in their own life? I'm glad you bring up that concept of health spin, right? It's not just about adding years to your life, but life to your years. When asked how long people wish to live, and offered a choice between the 85, 120, 150, or indefinitely, most people,
Starting point is 00:18:10 which surprised me, about two-thirds, said that they'd only want to live to 85. But when that question was reframed as how long do you wish to live in guaranteed mental and physical health? Ah, then all of a sudden the most popular answer jumped to an unlimited lifespan, right? That raised this concept of healthspan, the period of life spent in good health, free from chronic disease and disability.
Starting point is 00:18:35 What's the point of living longer if you can't enjoy it vibrantly? Unfortunately, here in the United States, we're living shorter and sicker. Life expectancy peaked in 2014. The United States has basically declined every year since, and that was before COVID kneecapped a couple years off our lifespan. And so we are raising the first generation of Americans to on average live shorter lives than their parents. This is primarily due to the obesity epidemic,
Starting point is 00:19:01 leading to diabetes and other metabolic issues. And so this is a critical time to have resources like this podcast to help people really take responsibility for their health. Again, there's tremendous power we can exercise over our health and longevity, but we need to intentionally choose to do it. Yeah, I love that you said that because this podcast is really about We need to intentionally choose to do it. Yeah. I love that you said that because this podcast is really about intentional choices and it's the micro choices that each of us make in the moments that fill out our day that end up changing our trajectory from either good or bad.
Starting point is 00:19:40 From either the health span that you talked about to one that's filled with disease, so appreciate your perspective on that. from either the health span that you talked about to one that's filled with disease. So, appreciate your perspective on that. So, your book meticulously examines 11 pathways of aging, and it offers insights into how these processes can be slowed or disrupted. Can you go through perhaps two of them and how understanding their mechanisms can inform strategies for promoting longevity? Yeah, so that's part one of the book where I identify kind of the 11 most promising pathways for slowing the sands of time, ending each with practical
Starting point is 00:20:15 takeaways for targeting them naturally with diet and lifestyle. So boosting the anti-aging enzymes and hormones, AMPK, FGF21, sirtuins and telomerase, while suppressing the anti-aging enzymes and hormones, AMPK, FGF21, sirtuins, and telomerase, while suppressing the pro-aging enzymes and hormones, mTOR and IGF1, decreasing glycation, inflammation, oxidation, and senescence, while preserving autophagy, or telomeres, and slowing the so-called epigenetic clock. I know these are all kind of fancy-sounding scientific terms,
Starting point is 00:20:41 but I really do try to break it down into the easily understandable, kind of doable, practical takeaways. So just to take a few… So autophagy, for example. Autophagy is considered kind of the primary system for cleaning the body from the inside out, clearing away accumulated cellular debris that may be contributing to the aging process. And so, there are some food components that actually suppress autophagy,
Starting point is 00:21:10 suppress this anti-aging pathway, like acrylamide, which is a toxin concentrated in potato chips and French fries, which is formed during the frying process. If you absolutely must have your French fry fix, air frying produces 90% less acrylamide, so that would definitely be the choice. There are some food components that actually boost autophagy. For example, chlorogenic acid, the primary antioxidant in coffee,
Starting point is 00:21:36 which may explain why those drinking three cups of coffee a day have about 13% lower risk of dying from all causes put together compared to those who don't drink any coffee because of this autophagy-activating compound in coffee. Also in foods, something called spermidine, which out of thousands of life-extending compounds among the small subset with the fewest side effects, spermidine has the largest documented lifespan extension,
Starting point is 00:22:02 and is found concentrated in beans, legumes. So beans, split peas, chickpeas, and lentils, also found concentrated in white button mushrooms, though the most concentrated source on a gram-for-gram basis, not on a per serving basis, is wheat jar, actually. And so I encourage people to add wheat jar to their daily diet to get their spermidine, which is considered an anti-aging vitamin, because when we're younger we may be able to eat enough,
Starting point is 00:22:27 but as we get older our levels of spermidine drop as much as 50% by the time we reach our 50, so we may need to start ensuring we're getting enough in our diet to ensure autophagy into old age. Two other ways to improve autophagy. One is water-only fasting. Unfortunately, it takes two to three days to really ramp up autophagy, one is water-only fasting. Unfortunately, it takes two to three days to really ramp up autophagy in human beings, and that's really too long to go unsupervised safely. But there's another way to activate autophagy.
Starting point is 00:22:56 We can fast or go fast. Exercise induces autophagy. Though you have to do it enough, 60 minutes of moderate intensity activity like brisk walking can boost autophagy based on muscle biopsies taken before and after, but only 20 minutes fails to move the needle. And so those are some of the takeaways from my autophagy chapter. I don't know if there's any other particular aging pathway you want to dive into, but I'm happy to jump wherever you want to go.
Starting point is 00:23:24 No, I wanted to ask you a further question on autophagy, because when I think about it, it's really your body eating itself. It is. In fact, that is the Greek roots, right? Self-eating, right? Autophagy. And I do intermittent fasting every single day. Typically, I fast for 16 hours and I eat during an eight hour window. Nice. I was recently listening to a podcast by Peter Thiel and he said that. From what he has researched, a top of G does not happen if you are fasting unless you were fasting, he was saying for four to five days before it kicks in, which to me would be very difficult for me
Starting point is 00:24:05 to do on a routine basis. What is your thought on that, and what is your thought overall on intermittent fasting? Right, well, so Tia's right in that it takes days for autophagy to ramp up, although you should be able to get within two to three days, you can see ramping up. But again, even that's too long to go without medical supervision, in my opinion. On the internet, you'll hear autophagy activated within hours of not eating, and so they encourage people to do this kind of time-restricted feeding to boost autophagy,
Starting point is 00:24:34 but that's all based on rodent studies. Rodents have much higher metabolism. In fact, a couple days of fasting can be deadly for rodents, and they lose a huge amount of their body mass even just after a day of fasting. But in human beings, when you actually put it to the test, it does take days to ramp up. Thankfully, there's other ways to activate autophagy,
Starting point is 00:24:52 like the aerobic exercise, which everybody should be doing anyway, along with these dietary tweaks. But there are other benefits to time-restricted feeding. In fact, in my book, How Not to Diet, the largest chapter on accelerating weight loss was indeed intermittent fasting, because there's so many different types, alternate day fasting, 5-2 fasting, 25-5 fasting, memmicking diets, time-restricted feeding, etc., etc. Really the bottom line, although I talk about the pros and cons of each,
Starting point is 00:25:17 is early time-restricted feeding has a variety of benefits. And so exactly like something you're doing, restricting your daily feeding window to 12 hours or less, eight's even better. But, critically important, it has to be earlier rather than later. If you skip any meal, you're skipping dinner, not breakfast. In general, we should try to squeeze as many calories earlier in the day as possible.
Starting point is 00:25:39 Ideally, breakfast or lunch would be the biggest meal of the day because of our circadian rhythms. The exact same food eaten in the evening is more fattening than the exact same food, exact same number of calories eaten in the morning. It causes more of a blood sugar spike, triglycerides, etc. And so if you're going to eat junk, eat it in the morning, your body is just better able to handle it, thanks to this really fascinating field of chronobiology,
Starting point is 00:26:03 the effect of our circadian rhythms have on our metabolism. Okay, and I happened to be researching some other podcasts you were on, and I heard you quote this study that was done about cardiovascular disease, where they were looking at people, I think it was in St. Louis, and they ended up, I think, examining 600 patients
Starting point is 00:26:23 who had died and how many of them had cardiovascular disease. And then they looked at the same amount of people in Africa. I think it was Gonda. And I was hoping you might be able to share that because to me, this illustration was just shocking between how people in Africa are eating and living and how we in the United States are. Yeah, it really goes back to, well, wait a second,
Starting point is 00:26:50 where did Pritikin get this idea of reversing heart disease with his diet centered around whole plant foods? Well, it all goes back to this network of missionary hospitals set up by Western doctors in sub-Saharan Africa, which uncovered one of the most important advances in health, really according to one of the most prestigious medical figures of the 20th century, Dr. Dennis Birkett, that the fact that in these countries, our most common and major diseases
Starting point is 00:27:16 were universally rare, like heart disease. In the African population of Uganda, for example, coronary artery disease was almost non-existent. You say, wait a second, our number one killer, almost non-existent, what were they eating? Well, they're eating lots of vegetables and greens, their protein almost entirely from plant sources, and they had the cholesterol levels to prove it.
Starting point is 00:27:34 Very similar to kind of modern plant-based eaters. And you say, wait a second, maybe the Africans were just dying early from something else, never lived long enough to have a heart attack. That's where that St. Louis study comes in. And so if you look at age-matched heart attack rates in Uganda versus St. Louis, out of 632 autopsies in Uganda, one myocardial infarction, and it was evidence of a healed myocardial infarction, so it wasn't even the cause of death.
Starting point is 00:27:59 Yet out of 632 autopsies in Missouri, same age and gender distribution, 136 myocardial infarctions, so 100 times the rate of our leading killer. In fact, they were so blown away, went back to another 800 autopsies in Uganda, and still just that one small healed infarct. Out of 1,427 patients, less than 1 in a thousand, whereas here in the United States, a heart disease is an epidemic. In fact, atherosclerosis is a disease that begins in childhood by age 10. The arteries of nearly all children raised on the standard American diet
Starting point is 00:28:31 already have what are called fatty streaks in the arteries, which is the first stage of the disease. These streaks then turn into plaques in our 20s, get worse in our 30s, and then can really start killing us off. In our heart, it's called a heart attack. In our brain, the same disease process can cause a stroke. And so, the earlier the better we can heart attack in our brain, the same disease process can cause a stroke. And so the earlier, the better we can get to improve our diets, the better.
Starting point is 00:28:48 But importantly, it's never too late. It's never too late to start eating healthier, never too late to stop smoking, to start moving. We really do have the power. So on this whole line of cardiovascular disease, one of the things that many Americans deal with is high cholesterol levels. And it's interesting because a lot of doctors will tell you to eat steel oats as a way to reduce it. But what are some of the examples that you would tell people to do if they wanted to reduce their cholesterol levels? Oh, the steel-cut oats would be great, or even better, uncut oats, which are oat groats, what you have before you cut them two to three times to get steel-cut.
Starting point is 00:29:27 It can get a lot of soluble fiber, which helps remove cholesterol from the body. The most important thing is the cut down on the three things that increase cholesterol in our bloodstream. One is saturated fat, which is found in concentrated meat, dairy, and processed junk. The number two, trans fats, found in these partially hydrogenated oils, as well as meat and dairy, and then three dietary cholesterol found concentrated mostly in eggs. The overall meat is the largest single intake in the United States,
Starting point is 00:29:54 just because people eat so much meat. And so that should bring, just reducing those three components that elevate our cholesterol, really should bring one's cholesterol down to where we want, which is if you don't have heart disease or diagnose heart disease, we really want a total cholesterol of about 150, or LDL, or so-called bad cholesterol, down around 70, and that really is where the bell curve averages out. Now, because of genetic factors, you still may be high, even if you're cutting down all that junk, in which case you have to add to your diet foods
Starting point is 00:30:25 that actively pull cholesterol from your system. And that's Dr. David Jenkins, the University of Toronto, the guy that invented the glycemic index, very prestigious. Researcher developed this so-called portfolio diet, developing a portfolio of different foods that pull cholesterol from your body, so it's a strictly plant-based diet, but adding things like the oats, the soluble fiber foods,
Starting point is 00:30:47 slimy foods like oats and eggplant and okra, that kind of stuff, and also adding nuts for these phytosterols and a variety of other foods. So I encourage people to check that out. Now beyond just dietary interventions, certainly quitting smoking, will reduce your risk for cardiovascular disease, aerobic exercise. But the good news then, again, we have tremendous power over our risk of getting a diet from the number one killer. Look, if that's the only thing a plant-based diet could do,
Starting point is 00:31:16 reverse our risk of the number one killer of men and women. Shouldn't that kind of be the default diet, the proven otherwise? The fact that it is also so effective in preventing arresting and reversing other leading killers like type 2 diabetes and high blood pressure really seemed to make the case for plant-based eating simply overwhelming at this point. OK, and since we're on the topic of diet, let's talk about the second part of your book.
Starting point is 00:31:37 In it, you talk about both the Mediterranean diet and the Okinawan diet, which are two popular diets that many of the listeners might have tried themselves. What are your thoughts on both of those? Oh yeah, well so it turns out that based on studies of identical twins, only about 25% of the lifespan differences between individuals is due to genetics. So for what we can do over the majority, which we have some control, we can look at these blue zones, these areas of exceptional longevity around the world, where they may have up to 10 times the rate of centenarians,
Starting point is 00:32:07 those reaching triple digits. And so two of those, as you mentioned, actually three of those, two in the Mediterranean, one in Okinawa, have been found. So Okinawa Japanese, the second longest-living formally studied population in the world, the only population living longer than that is actually the red-white and blue zone, which is in Loma Linda, California, the vegetarian seven-day Adventists in Loma Linda, California, which are actually the longest compared to anybody,
Starting point is 00:32:33 and is actually the only blue zone that survives to this day. Unfortunately, all these other blue zones are really kind of historical artifacts of history. But what they all share in common is that regardless of which of these five blue zones that have been documented, they all center their diets around whole plant foods. So they're minimizing their intake of meat, dairy, sugar, eggs, salt, processed junk, and maximizing the intake of fruits, vegetables, whole grains,
Starting point is 00:33:01 these legumes, the beans, the peas, the peas, and lentils, nuts and seeds, herbs and spices, mushrooms, basically real food these legumes, the beans, the peas, the peas, lentils, nuts and seeds, herbs and spices, mushrooms, basically real food that grows out of the ground. These are our healthiest choices. Yeah, I actually saw another program where one of your tips of advice would be before you eat a meal, perhaps start with an apple and a glass of water. That's in How Not to Diet. Very cool. Yeah, this negative calorie preloading. And so eating an apple before a meal cuts down
Starting point is 00:33:29 kind of average caloric intake by 200 calories. In the meal you eat 200 calories less than the meal, you feel just as full eating 200 calories less. And so look, I mean an apple may only have 50 calories, right? So basically if you're eating apple before a meal, the apple has like negative 150 calories, right? It's like drawing calories out of your body. Same thing with eating a low energy density vegetable soup or something.
Starting point is 00:33:54 By eating soup before a meal, you are going to feel just as full, cutting down on calories. You're going to have hundreds of calories sucked out of your body, veritably, and even just drinking water. So before a meal has been shown, you can randomize people to drink water before meals or not, and you can get a significant acceleration of weight loss, and that's from a number of different mechanisms.
Starting point is 00:34:15 But yeah, so negative calorie pre-lateraling is one of my so-called 21 tweaks of all the things that have been shown in randomized controlled trial to accelerate the loss of body fat. And I love it. And I think it's really interesting. I'm just gonna go back to blue zones for a second because you mentioned the diet that they follow. The other thing that I think is pretty remarkable is there's two other things that I've studied that they do.
Starting point is 00:34:39 One is the concentration on the importance of relationships and the connections that they have with each other in the blue zone. And the other one that really ties into this is that they have a profound sense of purpose in when they get out of bed, what they're doing in their life that brings them fulfillment. So it seems like it's this combination of the diet, relationships, and having this overwhelming sense of purpose that really helps as well to increase this age and health span. They also have regular daily exercise, tend not to smoke,
Starting point is 00:35:18 so there's other factors, though diet appears to be the principal component, alone accounting for half the difference in lifespan between blue zones and the rest of the world. But I'm glad you brought up about social isolation and loneliness, both associated with higher mortality rates. For example, marriage appears to carry a survival benefit, but the apparent detrimental effects of social disconnection and bereavement may be mediated by refraining from substance abuse like alcohol and tobacco.
Starting point is 00:35:49 And when people are stressed, when people are lonely, they tend to eat more food, less healthy food, more likely to do illicit substances or alcohol and tobacco. And so that is much of the—which is kind of good news, meaning that as long as you're able to maintain your healthy habits, you can be stressed and lonely, and kind of maintain—without it affecting your lifespan, if you're able to maintain those healthy habits, but unfortunately they tend to go together. Okay, and Dr. Greger, I want to jump to part three of the book called
Starting point is 00:36:20 Preserving Function, and here you cover everything from preserving bones, bowel and bladder function, circulation, hair, hearing, bones, immune system, joints, mind, muscles, sex life, et cetera. I wanted to just hit on a couple of these. So the first one, I think when a lot of people feel like they're aging, I think bone strength is one of the things that comes top of mind.
Starting point is 00:36:44 So I was hoping you might be able to talk about how do you preserve your bones. Yeah, some of the takeaways from that chapter. First of all, stomach acid blocking drugs like Prevacid, Prilosec, people often overuse for acid reflux can increase the risk of bone fracture. I don't think a lot of people know that. So can tobacco and heavy cannabis use, associated with increased fracture risk. These bisphosphonate drugs like Fosamax, the most commonly prescribed drugs for osteoporosis, may help prevent hip fracture risk in high-risk individuals,
Starting point is 00:37:14 but come with these rare, serious side effects. So I encourage people to look at the pros and cons, and see if it makes sense for you. Calcium supplements are actually not recommended for most individuals due to their poor efficacy and poor safety records. We should, however, strive to get 600 mg of calcium a day from calcium-rich non-dairy food sources, and the reason non-dairy is because meta-analysis show high milk consumption.
Starting point is 00:37:39 Not only does it not appear to protect against hip fracture, but it is associated with premature death, probably because of the galactose, which is a breakdown product of lactose. Now those getting inadequate sun exposure should consider supplementing their diets with 2,000 in-nation units of vitamin D a day, the sunshine vitamin. Prunes, onions, tomatoes, and almonds, and large quantities of recent vegetables, appear to have bone protective effects. However, alcohol, soda, and coffee, though evidently not tea, appear to increase osteoporosis fracture risk.
Starting point is 00:38:08 Soy phytoestrogens may be safer than estrogen hormone therapy. For preserving bone, you can randomize people with soy milk or regular milk and see an improvement in bone mineral density compared to the dairy milk group. And finally, though, weight-bearing exercise can certainly improve bone strength. Since most of the osteoporotic fractures are a function of falls, not bone density, fall prevention is the single most important intervention, which is good news because we can actually do something about it. Primarily a combination of lower limb strength exercises and balance training can significantly reduce the risk of fractures.
Starting point is 00:38:45 There's been seven randomized controlled trials showing that. So we really do have tremendous power of whether or not we're going to break your bones and all those deleterious consequences that follow from that. OK, well thank you for that. And I think another important one is preserving your mind, which I think there's been a lot of discussion about Alzheimer's and dementia and its rise, and so I think this is a hot topic for many people. No, absolutely.
Starting point is 00:39:12 In fact, it is the most feared condition of later life, and tremendous public health challenges. In high-income countries, heart disease is killer number one, dementia is killer number two, butementia is killer number two. But though Alzheimer's may be incurable, at least it is preventable, and that is the good news. Modifiable lifestyle factors outweigh the genetic component of Alzheimer's disease. Alzheimer's is related to the atherosclerotic plaque buildup in the brain,
Starting point is 00:39:43 so the same dietary changes that can help with cardiovascular health can also help with cognitive health. In other words, what's good for the heart is good for the head. So normalizing blood pressures, for example, in hypertensive individuals can help prevent cognitive decline. Aerobic exercise can improve brain function in both normal and cognitively impaired individuals. Part of that is by boosting something called brain-derived neurotropic factor,
Starting point is 00:40:09 which can also be boosted by meditation, caloric restriction, reducing saturated fat intake, and eating high flavonoid fruits and vegetables, so that's the least colorful fruits and vegetables like beans, berries, greens, and rye groats, also high in flavonols. Non-vegetarians have about two to three times higher risk of becoming demented, so maybe that's because of the saturated fat or oxidized cholesterol. Some of the pollutants like DDT in the diet that may increase our risk of cognitive dysfunction.
Starting point is 00:40:37 So the best kind of dementia-deterring diet would be low in added sugars, low in added salt, low in saturated fat, animal products, processed foods, and high in those whole plant foods, particularly greens, beans, and berries for reducing our risk of dementia. OK, and I want to just cover one more that I think a lot of people worry about, and that is their sex life as they get older. So, what are your tips there? In terms of sex life, well, something that I had never heard of before, there's a distinctive body odor of the elderly due to a chemical we start
Starting point is 00:41:08 producing as early as age 40 called tunaninol, which has this unpleasant, grassy, greasy kind of odor, which is caused by the oxidation of omega-7 fats, which are increasingly exuded from our skin as we age. But the good news is we can cut that odor by eating two things. One, mushrooms. Randomized controlled trials have shown mushrooms can help, as well as chlorophyll-rich dark green leafy vegetables. So, in terms of smelling better as we age, which may have to do with romantic life, in terms of function, sexual responses for both women and men are related to blood circulation.
Starting point is 00:41:44 So, again, dietary and lifestyle changes that are good for the heart, also good for the genitals. And indeed, men and women randomized to healthier diets can experience significant improvement in sexual function, and this may be due to the anti-inflammatory effects, the blood vessel dilating compounds in certain fruits and vegetables like watermelons and beets, or lowering the phthalates and BPA exposure that we may find, these plastics chemicals that are found in a lot of processed foods.
Starting point is 00:42:09 In terms of sexual desire, there is a dangerous and ineffective drug prescribed for women called filcerabin, which should be avoided. Similarly, there's not enough safety data to prescribe testosterone for women to warrant FDA approval. However, what has been shown to help improve sexual desire in women, which is one of the main complaints with aging for women and sex life, is lavender and bitter orange aromatherapy may help. In terms of some mental testosterone, can help low libido in men,
Starting point is 00:42:39 though the risks likely outweigh the benefits. Thankfully, there are safe natural ways to boost testosterone with diet and lifestyle changes, such as eating less than a teaspoon a day of fenugreek seeds, avoiding obesity, avoiding sleep deprivation, and beer. Actually, beer lowers our testosterone levels. The spice saffron can improve sexual impairment caused by these SSRI drugs like Prozac.
Starting point is 00:43:03 Mockaroot can improve sexual desire in men and sexual function in women. Ashwagandha, another root, may improve some aspects of sexual dysfunction, but there's a risk of liver toxicity, so I actually encourage people not to use it. About half of postmenopausal women experience something called the genitourinary syndrome of menopause, first-line treatment of which are low osmolality vaginal moisturizers and lubricants, and I talked about the few brands that actually fit the bill in terms of safety.
Starting point is 00:43:32 The second-line treatments are topical hormones, intervaginal estrogens, DHEA. Vaginal estrogen is safer and more effective than to manage these vaginal symptoms than oral hormones, and oral DHEA doesn't appear to work at all. However, oral fenugreek and topical fennel creams can improve sexual symptoms in postmenopausal women. And finally, in terms of erectile function, smoking cessation,
Starting point is 00:43:57 weight loss, and physical activity can help with erectile function. Though one type of exercise, prolonged cycling, can actually make it worse because you're pressing on that pudendal nerve. Men should know about drugs like Viagra can have both short-term and long-term adverse effects, and so you want to weigh the pros and cons. And though ginseng doesn't have any effect on female sexual dysfunction, korean red ginseng can significantly improve erectile function in men. I think those are kind of the main takeaways
Starting point is 00:44:25 in the sex life chapter. Okay, well, thank you for sharing that. And the fourth section goes into your anti-aging eight. And these are things such as nuts, green berries, microRNA manipulation, probiotics and probiotics, caloric restriction, et cetera. And I wanted to just go through a few of these. The first one I wanted to talk about,
Starting point is 00:44:47 because it's something that much of the audience might not be familiar with, is xenohormosis. Oh, so interesting, right? So yeah, xenohormosis and actually microRNAs represent these kind of cross-kingdom communication pathways between plants and animals that we may be able to use to our advantage, providing both a reminder and mechanism for the importance of exercise and centering one's diets around these kind of unprocessed plant foods.
Starting point is 00:45:15 Hermetic stress is the—hormesis is that which doesn't kill you makes you stronger principle. Hermetic stress explains the health and longevity benefits of exercise. So, exercise actually causes little micro tears in our muscles, stronger principle, hermetic stress explains the health and longevity benefits of exercise. So exercise actually causes little micro tears in our muscles, it actually causes damage to our body, but in our body's repair, we actually end up better than we started out with. Also can help explain the benefits of chloric restriction,
Starting point is 00:45:37 as well as certain foods and beverages like broccoli and green tea. So for example, green tea you think of as an antioxidant beverage is actually a pro-oxidant beverage, but it has overall antioxidant effects because it ramps up your body's antioxidant defenses. Same thing with broccoli. Our body sees broccoli as this invading compound and boosts our defenses, so we actually end up better off than we would otherwise. The xenohormesis comes in, and it's just like antioxidants can be kind of commandeered from plants for our own benefit.
Starting point is 00:46:06 So might these xenohormetic stress compounds, like polyphenols, which can actually help affect by modulating this microRNA expression. So there's been this kind of failure of kind of isolated phytonutrients in like supplements to replicate the benefits of whole plant foods, and that may be due for a variety of things. Maybe people are overdosing in these supplements, or the lack of whole plant foods, and that may be due for a variety of things. Maybe people are overdosing in these supplements, or the lack of synergistic reactions between the thousands of different compounds in foods that are actually as grown.
Starting point is 00:46:32 But there also may be this kind of manipulation of human gene expression by these xenomicroRNAs, again, a way in which there's this kind of genetic communication between plants and animals, which is a fascinating field. This is something that wasn't even discovered by the time I graduated medical school. It really challenges the central dogma of biology, but really helps explain why, oh my God, no wonder these foods are good for you, these foods are bad for you, because they actually affect the gene expression within our body.
Starting point is 00:47:00 Dr. John B. Reilly And I think another one that people might be interested in is the role of prebiotics and probiotics in supporting gut health and longevity. Oh yeah, oh so fascinating. The problem historically with kneeling down this interaction was because foods that are good for our gut are good for us generally. So when you eat a lot of prebiotics, that which feed our healthy gut flora,
Starting point is 00:47:26 where the resistant starch dietary fiber, where is that found? Oh my god, really healthy foods, right? So eating kidney beans or something. And so, wait a second, eating kidney beans helps health, but yeah, is there a microbiome interaction or not? Well, we didn't know until these fecal transplant studies come along where you can actually transplant the microbiome between people,
Starting point is 00:47:43 between animals, and actually prove cause and effect. And so you take mice that are genetically manipulated to have better exercise fitness, and you transplant their microbiomes to other mice, you can actually get an improvement in aerobic capacity, proving that, oh my God, even our microbiome even plays a role in our physical fitness. And so basically prebiotics, like the resistant starch and dietary fiber, feed our probiotics, which are the good bacteria themselves, the acidophilus,
Starting point is 00:48:08 bifidobacteria, that make beneficial postbiotics like butyrate and acetate. That's why probiotics are so good for us, because they create these byproducts that are then absorbed through our colon walls, circulate throughout our bloodstream, across the blood-brain barrier, and actually can affect our mental health as well, and decreasing inflammation, boosting our immune function, etc. However, feeding the wrong foods can actually foster the growth of bad bacteria, which create toxic post-biotics like TMAO, this trimethylamine oxide.
Starting point is 00:48:37 The bottom line is our health is inextricably linked to the health of our microbiome, and these fecal transplant studies prove that a preponderance of health-promoting bacteria in the colons of centenarians may not just be kind of a biomarker, but actually an active promoter of healthy aging. You do fecal transplant studies, you feed mice the poop from a centenarian, and they actually live longer, proving that, oh my god, there's some longevity benefits of the microbiome.
Starting point is 00:49:05 Intestinal dysbiosis, meaning having bad mix of bacteria in the gut, may actually accelerate aging via leaky gut, but we can seal up a leaky gut with these short-chain fatty acids which are produced in response to fiber-rich diets, adequate zinc intake, reduced exposure to alcohol, and reduced exposure to these NSAID drugs like aspirin and ibuprofen, which can play havoc with our gut lining. And then we can prevent the dysbiosis, this bad mix of bacteria, in the first place by reducing unnecessary exposure to antibiotics, including antibiotic residues
Starting point is 00:49:38 in typically industrially produced meat, reducer intake of excess sulfur-containing amino acids like cysteine methionine, found concentrated in certain foods like dairy, decreasing our intake of certain artificial sweeteners and emulsifiers, which can interfere with our microbiome, as well as maximizing our intake of these fermentable carbohydrates like the fiber and the resistant starch, which we can't actually digest, but so it makes it all the way down to our colon and creating this kind of prebiotic bounty for our good gut bugs. In terms of decreasing TMAO levels, that's reducing our intake of animal products
Starting point is 00:50:14 and carnitine supplements. So there's carnitine found in some kind of energy drinks. That's another thing that can create, that can foster the growth of these bad bugs. In terms of, well, why feed our good gut bugs, and we can just take good gut bugs by eating probiotic supplements. Unfortunately, they have been generally found to have questionable safety, efficacy, and purity on the market, and so which really the best way to go about it is by eating prebiotics. With our good gut bugs eaten, then they can be fruitful and multiply
Starting point is 00:50:40 and create an environment by which they can do well. In fact, we have randomized controlled trials where you give people, randomize people with prebiotics, and placebo can significantly improve muscle strength. And frail individuals significantly improve exhaustion. And so these prebiotics are found in these unprocessed plant foods. And there's other prebiotics, which many people haven't heard of, urolithins are found concentrated in certain foods like pomegranates, that can help explain the health benefits of diversity of whole plant foods.
Starting point is 00:51:08 Okay, well I appreciate that whole perspective. And the other thing I like to tell people is, through the work of Chris Palmer and others now, we're also seeing the link between gut health and mental health as well. Yeah, fascinating, absolutely fascinating. Right, so you can like, the anti-inflammatory effects, you can decrease asthma attacks in individuals by feeding their microbiome,
Starting point is 00:51:28 and you get this, the butyrate in the system which suppresses the excess inflammation. Really remarkable effects. And we used to think our good gut box is just about digestive health, right? Reducing intestinal inflammation, but now we know that these compounds circulate throughout our body,
Starting point is 00:51:42 across the blood-brain barrier, and can have effects really across the board. Okay, and then I had one last question for you. We talked about coffee a couple times today, and the other thing I wanted to mention was red wine, because these are two things that people love. What's your thoughts on each in their role of promoting longevity? Yeah, in my chapters in How Not to Die on liver disease, depression, and Parkinson's, I talk about the benefits of coffee for the liver, mind, and brain.
Starting point is 00:52:09 Coffee drinkers do live longer and have lower cancer rates overall, although not for everyone. Coffee can worsen acid reflux disease, bone loss, and glaucoma. Otherwise, though, coffee is good for you, though every cup of coffee is a lost opportunity to drink something even healthier, which is a cup of green tea. So three cups of coffee a day associated with 13% lower risk of all-cause mortality, three cups of tea every day associated with 24% lower risk.
Starting point is 00:52:36 So tea is better, though they work through entirely different mechanisms. The coffee has an autophagy-boosting effect, whereas the green tea is this hormetic antioxidant defense-strengthening strategy. So presumably both would be kind of additive, and so it's not kind of either-or, but you can kind of start out with coffee in the morning, switch over to green tea,
Starting point is 00:52:55 and then switch over to decaf or herbal tea later on. I talk about the benefits of Honeybush Tea, Roy Beaux, Cam Neal for their various anti-aging properties. But then in terms of alcohol, everyone agrees that heavy drinking, drink during pregnancy, binge drinking, bad ideas. But there's been this controversy about moderate drinking. Those who tend to live the longest are not the abstainers who drink zero alcohol, but those who imbibe a few drinks a week.
Starting point is 00:53:24 Unfortunately, this appears to be an artifact of the so-called sick-quitter effect, which arises from the systemic misclassification of former drinkers as if they were lifelong abstinents. It's the same reason sometimes you see higher mortality rates among those who quit smoking compared to those who continue to smoke. Why? Because why did they quit smoking? Ah, they got sick. So of course, no wonder those that aren't smoking, these quitters, these new quitters, have even worse health.
Starting point is 00:53:53 So it's not the abstention led to poor health, but rather the poor health led to abstention. So when you go back and control for that sick quitter effect, then unfortunately that so-called J curve disappears, and there's just this kind of dose response increase of more disease with more alcohol, with no apparent protection at lower levels of consumption. So, according to the Global Burden of Disease Study, the World Health Organization, the World Heart Federation,
Starting point is 00:54:18 the safest level of drinking is sadly none. Grapes, barley, and potatoes best eaten in their non-distilled form, and Johnny Walker no substitute for actual walking. Thank you for sharing that, and where would be the best place the audience can go if they want to learn more about you and your work? Oh, they can go to nutritionfacts.org, where all my work is available free. There are no ads, no corporate sponsorship, strictly not commercial, not selling anything, just put it up as a public service, as a labor of love, as a tribute to my grandmother.
Starting point is 00:54:52 Well, Dr. Greger, thank you so much for joining us today. It was such an honor to have you. I'm so happy to be here, looking forward to coming back on after my next book, which will be on cancer. Oh, fantastic. Would love to have you back to discuss that. I thoroughly enjoyed that interview with Dr. Michael Greger.

You're about to hear a preview for a special passion struck podcast interview that I did with astronaut Steve Bowen, a true hero from the depths of the ocean to the reaches of outer space. We'll delve into the critical moments and the decisions that propelled Steve's career to another hemisphere. He'll share how he tackled self-doubt
Starting point is 00:56:10 and the unexpected twists on his path to the stars. From record-breaking spacewalks to seeing Earth's fragile beauty, Steve brings a fresh perspective on the highs and the lows of space exploration. I was literally on top of the space station. We were installing an antenna on top of a space station. And so I kind of clipped myself in and got my hands free
Starting point is 00:56:28 and sat back and watched the world pass below me for about 25 minutes or so. And what struck me was the reality that what kind of civilization do we have that allows us, all these countries working together, to put people in space, not just to go to space, but really to research and challenge ourselves and to explore and to really improve life on Earth.
Starting point is 00:56:51 I grew up carrying buckets of cement for my dad. It was not anything I could conceive of to be sitting on top of the space station, installing an antenna. Sometimes I think we all have to stop and take a look, look around us, look at our environment, just look at the civilization we have, we're living in. It may seem in such turmoil on any given day, but really billions of people are living together and getting along and that's remarkable. And I don't think we necessarily appreciate those aspects of it. We actually can solve problems when we all work together. We actually can take care of this incredible planet. We challenge
Starting point is 00:57:29 ourselves to understand it and understand how to make it work. The fee for this show is that you share it with family or friends when you find something helpful or useful. And if you found this episode with Dr. Greger useful, then definitely share his advice on graceful aging with those that you love and care about. In the meantime, do your best to apply what you hear on the show so that you can live what you listen. Now, until next week, go out there and become passion-struck.
