Welcome back. I am here with Dr. David Perlmutter, neurologist, teacher, best-selling author,
one of my close friends that I am grateful for that.
And I was just telling him at the break that he's just so eloquent in how he explains why you should be doing the right things.
And so here we're going to talk about foods to choose and foods to lose. And we had breakfast together in Westlake, north of Los Angeles. And we were
actually really good with what we were eating. So to help brain warriors think about what are
the things to choose? I mean, let's start there because when you get the list on the things to choose. I mean, let's start there because when you get the list on the things
to not eat, they go, oh, there's nothing left to eat. And in fact, there are thousands of things
to eat. Yeah. And there are such great books written these days about preparing foods and
and the incredible variety. But I think as a big macroscopic view,
your plate should be colorful
in the most natural way that it can be.
And, you know, I have been,
people have said that, you know,
the grain brain diet is pretty much Atkins redux,
meaning, oh, it's all about eating meat
and eggs and dairy products, and that's it.
Well, in actuality, we've never said that, and nor is the new revised edition about that.
It's about having a plate that mostly reflects above-ground colorful vegetables, rich in dietary
fiber, rich in vitamins, and rich in minerals as well well if it's organically raised.
I certainly think that the main consideration in terms of the plus side is dietary fiber along with healthful dietary fat. Protein can be from plant or animal sources. If it's an animal
source, then by all means, fish should be wild. In my opinion, poultry should be free range and
beef, if you choose to eat beef, should be grass fed. But make no mistake about it, you can be
wonderfully healthy and be on a vegetarian diet. You can be in ketosis, for that matter,
and be on a vegetarian diet. There's a wonderful book out by Dr. Will Cole called Ketotarian.
And in that book, he describes how you can get into this,
let's say an extreme state of higher fat, lower carb.
The manifestation is being in ketosis by being on a vegetarian diet.
Who knew?
Well, you know, pretty much if we didn't kill something
or find it dead on the ground, we were, historically, hunter-gatherers, part two of the gatherer part, is gathering up vegetable sources of, you know, rather plant foods that you find and eating them, high in fiber. that underscores the paleo mentality of eating what our ancestors ate, because it was a pretty
darn good diet. After all, it kept us here for a couple million years. And I would certainly want
to explore for just a moment the relationship of food beyond its macronutrient content of protein,
fat, and carbohydrates, and even beyond the micronutrient content of protein, fat, and carbohydrates,
and even beyond the micronutrient content of minerals and vitamins.
That food is information.
Food, the foods that we choose to consume,
are actually changing our gene expression moment to moment.
There was a terrific article that came out in October 2008 by Dr. Tang at the University of Louisville.
And his report in the journal Cell, Host, and Microbe was very fascinating for me because it
connected two very important dots. We like to talk about food as information. We've been doing it for
many years. But he demonstrated that plants can release what are called exosomes, which contain their genetic material, RNA, that then makes its way to the bacteria that live within us when we consume these foods, these plants.
And these exosomes then work their way into the bacteria and inject their RNA, and that influences the gene expression of the bacteria that live
within us.
Wow.
We are changing the gene expression of the bacteria living within us based upon the genes
found in the plant that we ate.
The effects upon the bacteria are at least threefold.
It affects their rate of replication, how quickly they grow. It affects what they do
metabolically in terms of the products they're producing, and it affects their location in the
gut. Their location changes based upon the food that we eat. Why is that important? It's critically
important because some bacteria need to be located near
the lining of the gut so they can go to work to repair the damaging effects of our diets to the
gut lining and therefore help us reduce inflammation. Again, the cornerstone of degenerative
condition. So this is a powerful connecting of dots that just doesn't keep me up at night, but almost could relating the genetic material
of the food we eat to through the bacteria in our gut to our ultimate health. And I didn't think
about at the time, but as I've no pun intended, digested this research since then, I've begun to
think about how valuable and important considering the genetic material of our
plants is in the context of gene manipulation. So genetically modified foods then may very well
pose a threat because they do change the genetic expression of our gut bacteria and may therefore have an effect upon our health
that has never ever been explored by any of these agribusinesses that are producing these
genetically modified plants that are consumed almost globally. So that's what we should eat,
what we shouldn't eat. I think I've made that clear. We've got to stop sugar and other refined
carbohydrates, the bad oils, the high inflammatory omega-6 oils that line the grocery store shelves.
I think artificial sweeteners are among the biggest threat on the planet today because of
the changes that they impart on the gut bacteria. Two days ago, there was an interesting
article in the New York Times science section talking about why artificial sweeteners are
probably a pretty good idea, not really associated with weight loss, but better than sugar. And I
commented on the article and they published the comment. I was very happy to see that
saying, well, unfortunately you neglected to talk about the incredibly increased risk of obesity and type
two diabetes in people consuming artificial sweeteners. Somehow the researcher writing
the article neglected that. So what irony it is that artificial sweeteners are associated with
dramatic weight gain and risk for diabetes
when that's the reason people are using them in the first place.
So, you know, it's about getting that information out.
And let me say one other thing that's interesting along the lines of sugar.
Several weeks ago, I was on the CBS This Morning program.
And I had a new book coming out of this.
And Dr. Perlmutter has this new book, and it's based on a book from five years ago.
In the book, Dr. Perlmutter talks about the dangers of sugar as it relates to the health of the brain.
Before they get to me for the interview, they said,
but we reached out to the sugar industry for their comment.
Big poster.
And they said, sugar is great in moderation as decades of research would have you believe
then they turned the camera to me and i just took a deep breath and smiled and i said well you know
that's what they said about tobacco years ago and uh and can we move on now and so uh but you know
it as a side note it's just an interesting kind of commentary in terms of where television has gone these days.
Everything is negative.
I'm a guest in their home on your set.
You know, I've come up to New York to do your show, to tell people what they can do to maintain their health and make lifestyle changes. And right off
the bat, it's, oh, yes, but Dr. Polin, don't you know that sugar is actually good for you? And
it got worse from there on. But that's okay. I mean, our mission, yours and mine, and so many
others, is to light the candle. My goodness. But that actually goes into another part of your work, which is society, especially the news media, setting up conflict and negativity as a way to increase their ratings. Although you and I both have been able to do that on public television where we have an hour with viewers to teach them.
And we're not into conflict.
We're just into information.
And people love that, right?
I mean, your shows, my shows have been wildly successful in educating the population.
A couple of things, dairy.
So you had mentioned dairy. My worry about dairy is almost all of it is raised with hormones and antibiotics.
And most of us don't have the enzyme to process it.
Plus, when you mix casein with stomach acid,
I'm not sure if I learned this from you,
but if you mix it with stomach acid actually turns into caseo morphins that
work on the heroin centers of your brain.
So generally,
you know,
I make Tana pumpkin spice,
almond milk,
cappuccino in the morning.
You know, I pretty much try to stay away from dairy.
You're a good guy.
I am.
It's how I tell her I love her, which just makes my life better in so many ways.
But talk about dairy just for a minute, and then we're going to move on and talk about
the gut in our next podcast.
By and large, dairy is a very threatened food. I think if people want to put cream in their coffee, having a little organic milk
wouldn't be aggressive. I think butter, organic raised butter isn't necessarily the worst choice,
high in butyrate. But by and large, what is milk? Milk is a concentration, a liquid that's concentrated in that animal,
typically the cow, from everything that cow has been exposed to.
And this bioconcentration of hazardous things to which that animal has been exposed
is extremely worrisome, especially in the factory farm where that animal is given food to eat that may well
have been sprayed with glyphosate, the herbicide active ingredient in Roundup, with that animal
losing some of its antibiotics into its milk, and who knows what else. Hormones have been
given. We know that's been done for quite some time. So I think that there are good vegetarian
substitutions for cheese, and I'm all in favor of it. And I think what we were talking about in
our new book that comes out next year is there's a book written called One Meal a Day by Susie
Cameron. And it is a book that talks about the impact on your health and also globally,
environmentally, if we all shift to at least one plant-based meal a day.
And we're all over it.
I think it's a great idea.
I think the less animal products in general is probably going to turn out to be the best choice.
And that's a stronger position towards plant-based than I have taken in the past.
So is my position changing?
You bet it is. And that's a good thing that Dr. Perlmutter and Dr. Amen and others change their position
with time as we learn more. So I think by and large, I might put a little
whitener in my coffee, a milk-based whitener in my coffee, but beyond that, I'm not a huge fan.
You know, one of the things that I often think about is when humans are upset,
when we're depressed, when we're isolated, when we're lonely, when we're angry, we produce certain chemicals that are associated with that.
Our body actually responds immediately to the quality of thoughts we have. Well, the same thing is true with animals. When animals are lonely, when they're depressed, when they're angry, they're producing chemicals that are associated with those conditions.
And I think if you eat animal protein that's not sustainably raised, where they're really thinking about the humane aspects of it, is that we are also getting those chemicals that clearly are not
good for us. Well, I want to go back to something you said a moment ago and underscore
the mention of caseomorphin. The fact that we create these morphine-like chemicals,
gluteomorphins found in wheat, for example,
that we are consuming these chemicals
that ultimately stimulate the opioid receptors
in our brains by the very nature
of the foods we're eating.
And I want to talk about that
in the context of the opiate crisis.
So keep that thought
because we have to go to the next podcast.
But I would love
for us to talk about the addictive nature of food. So stay with us with Dr. David Perlmutter. His
new book is the revised version of Grain Brain, truly a historic bestseller and just wonderful book that you should read. Stay with us.
