Chapter 1: What are the top misconceptions about healing the brain?
If you had to think about it, what are some of the top one or two big lies that are still out there that are governing how people are maybe misguidedly approaching healing the brain?
I think the one that sticks out for me is differentiating between treatment and that we have a lot of treatments that work. I think people are really misinformed. I think the idea that when you have depression or anxiety, you come to see someone like me, an expert in treating those that, you know, it's going to be an arduous or difficult or complicated thing, you know, sometimes for sure.
But I think a lot of people get better. I think another one of the pieces of misinformation that's out there and what's really changed, I think the motivation for this book is we've got to do a lot more, Drew.
like the modern world is coming for your mental health in a way that we're all seeing you know there's a lot of some ways controversy what's making all the numbers go up why are so many more people depressed why do so many people more people have conditions like autism and ptsd etc And certainly there are some concerning root causes of those in our environment.
And I think what this book wanted to do is to ask people to think about what are the evidence-based tenets, what are things that we can agree on that are vital for our mental health, kind of like with nutrition. And it's just changed so much that there is low-hanging fruit for a lot of us in terms of improving our brain health and mental health.
So I think that in some ways that big lie out there is that we don't know, that we can't figure this out, and that you are in a state where you shouldn't have a lot of confidence about your own potency to heal your mental health.
And I'm all for people getting lots of professional help, but I also think there's so much in the evidence about some of our lifestyle choices that we've got to get the message out there
and then shift this model like probably the biggest lie as you call it is that you want to wait until you're symptomatic to see me i hate this model it's sort of the idea that like i'm only useful when you're really sick when you're in a crisis and i'm very handy in a crisis you know that's what i'm trained to do but i don't know You're probably not in the midst of a psychiatric crisis.
Drew, if we got into it about your mental health right now, you had some ideas, some concerns, some questions, some things you wanted to put on an agenda of, hey, we're going to engage in these types of maybe behaviors. We're going to have a conversation about some aspects of yourself or your history. We'd have a great mental health conversation.

Chapter 2: How are modern lifestyle habits affecting mental health?
You know, you mentioned something really important. I think a lot of people are at home scratching their heads and thinking, why are so many people having such difficulties with their brain? And why are so many of these mental health disorders on the rise? You mentioned there's a whole spectrum of them. Autism, Alzheimer's, neurocognitive issues, and everything else in between.
Depression, which takes a huge toll on our economy and the lives of people. When somebody comes to you and they ask you, why are people's brains so messed up in this modern day and age? How do you answer the question?
our brains are changing we just learned that there's a teaspoon of plastic in our brain you know not sensational science from the you know uh corners of the wellness world like in nature a teaspoon so our brains have never had a teaspoon of plastic in them before just just explain that for people that are not familiar you're talking about microplastics and some recent studies so sorry there's a big study came out in nature really one of our most respected scientific journals
looking at microplastics, nanoplastics, these very small plastic molecules, and finding there is a lot of that stuff in our brain. They estimated about a teaspoon. It's throughout our body. We don't know exactly what that does. There's some basic bench science that it can trigger more inflammation,
There's a concerning correlation between people who had dementia having more plastic in their brain. But I think it's an example of there's something new and there are clear steps. In our household for the last 20 years, we've tried to heat nothing in plastic. We don't have a lot of plastic.

Chapter 3: What are microplastics and how do they impact brain health?
there wasn't science that plastic was bad it just seemed i don't know like something that was kind of new and that was a little concerning based on some of the data i was seeing even back my first book in 2011 the happiness diet we went through a list of the chapter that got cut on toxins And all of these plasticizers were known concerning chemicals back then.
That was like, what, 15 years ago at this point? So when we talk about what's changed, there's more weird stuff in our environment. Not to fearmonger, but just to kind of be more clear. You can't kind of go around the world right now just kind of living your life, doing what everyone's doing.
You're going to end up doom-scrolling, eating mostly processed foods, getting lots of microplastics in your diet, getting lots of flame retardants. I mean... There's all kinds of kind of icky stuff out there. So what's changed? Some of that relates to mental health risk. Like why are there more mental health disorders now? One is more awareness. The other are environmental changes.
You know, the modern brain never had to deal with doom scrolling before. It's just, it's a very compelling algorithm driven, visually stimulating, intellectually stimulating device that we have.
So what do you think is worse? Doom scrolling or microplastics for the brain?
I think microplastics are probably worse for the brain because doom scrolling, you can, over time, curate your feed. You can get rid of apps. The difference between doom scrolling through a curated feed of lots of mental health advice and good stuff that inspires you versus the stuff that you tend to get fed, I think both of them are concerning.
And the idea right now is, hey, everybody, amidst all of that feeling, like, oh, no. It's overwhelming. Like, what do we do about our mental health? I think let's be realistic. Mental health rates are going up, right? When I finished training in 2004, 8% of teens had clinical depression. Today, 20% of teens have clinical depression. So something is radically shifted.
There are some really clear suspects in this. In some ways, the nine tenets come from that. I go over these factors that have changed. Look at the sleep of a teenager today versus 20 years ago. Look at the dietary and nutritional quality of food for a teen today compared to 20, 25 years ago. It's just radically shifted.
And so has some of these foundational parts of our self-esteem, like how we relate to people, how we connect with people. I'm not trying to say everything in the modern world is bad. I just think with a modern brain in the modern world, there's a new set of rules. There's a new set of science. And we've got to employ that if we're going to optimize our mental health.

Chapter 4: Which diets increase the risk of depression?
Even worse, a brand new study published in Science of the Total Environment revealed that a single scratch on a non-stick coated pan can release up to 9,100 plastic particles into your food. Yuck. I've been on a mission to swap out my toxic cookware with non-toxic options, which is why I use the Titanium Always Pan Pro.

For sure. I got rid of all my fancy teas and tea bags. I was really disappointed and upset. And I think, again, it's one of those things nobody meant to do this. But when you get those fancy nylon tea bags, they're coated in microplastics. I saw an estimate. It was two billion particles of microplastics.
Compare that to a paper tea bag or compare that to loose leaf tea where you're not getting any microplastics. So again, same great idea. Have a cup of tea in the afternoon, you know, mellow out, have some chamomile, have some mint. Just wonderful kind of wellness tip, I think, for all of us. Take a breath. And the idea that in doing that simple act, you were...
poisoning yourself with microplastics. It's just, again, one of those lessons from the modern world that we don't want to fear monger, but it's like, Hey, you got to shift your teabags, everybody listening, go, go, go see what you have. So I think that's one of, um, certainly the, the, um, lessons.
There was a great article by my favorite psychiatrist, uh, David Puder, who's the psychiatry and psychotherapy podcast host. They just published it in genomics. Um, looking at how do you get rid of microplastics. And there's not a lot of data, but there was one study where more of this plasticizer BPA would come out in the sweat.
And so some question of maybe more saunas is, again, a way to kind of get it out. Because the idea of, okay, we want to limit exposure, right? So you're not getting as much. Then over time, your body naturally clears everything bad. And that's kind of generally true. But are there things we can do to promote it? And so maybe sauna is a way to do that.

Chapter 5: Is the chemical imbalance theory a myth?
I mean, you can't ignore that data, especially, again, if, like a lot of us, you're feeling a little toll on your mental health. You're wanting to do more. With our physical fitness, we all have a lot to do, and I think we all have maybe some guilt. I was really proud I rode my bike to this recording session here. It's just a great way to start the day, but also just...
helping me achieve one of my goals, get some oxygen, extra blood flow to my brain. Those types of things, engaging in movement, engaging in good sleep, they really add up over time and I think make a big impact, as everyone knows, on our mental health.
If you had to rank some of these tenants that you talk about, and even the sub-tenants underneath them, if you had to rank food, environmental toxins, sleep, and a sedentary lifestyle, let's just start with those four. Okay. Right? So food, environmental toxins, environmental exposure, sleep, and sedentary lifestyle.
For the patient set that kind of comes to you, even though every person is different, what do you see as being...
um the top one and then take us from there generalizing to our population what's the taking the number one toll on our population and our mental health today i would say the top risks of the ones that you just described probably is sleep when you don't sleep well you're not cleaning out the waste in your brain you're not really processing all the complex emotions that we're having you're not consolidating memory so some of that brain fog just not feeling your best low mood
I kind of put sleep there as fundamental. It's hard for me to decide between sleep and nutrition, Drew, because they're so biologically foundational, right? Nutrition is, this is what your brain is made of. You've got a diet with a lot of magnesium or not. You've got a diet with a lot of omega-3 fats and fiber or not.
And so those two are really hard for me to differentiate between in terms of, again, like these foundational pieces.
Part of what I'm hearing you say is also if your sleep is messed up, that might be number one for you.
I just, you've got to, you've got to get sleep on. They teach us in psychiatry residences, you know, the most dangerous thing is when someone is not sleeping, your patients are sleeping, you know, it's okay. You can sleep. But if your patients are sleeping, like you've got to be very concerned, the risk. And I think everybody listening and drew, you know, to the risk.

Chapter 6: How can journaling and nature improve mental health?
And then the point I often like to make, and that was very important for me as a physician, we don't know where to get them. Everybody likes to debate which type of magnesium to take. Is it glycinate or is it citrate? But I find very few people know what their favorite magnesium food is or their top five.
And I think it's really important that we translate this knowledge about nutrition into our everyday choices of nutrition. You mentioned environmental toxins. And so I think that probably depends on exposure. Certainly some people listening, if you've had a lot of environmental toxin exposure, that might really be the top thing going on. I'm probably...
of the camp that it is the minority of people struggling with their mental health problem, that it comes directly from a singular toxin. And there's certainly certain examples of that in the literature and in the world. But, you know, there are certainly a few classic examples.
Someone gets mercury poisoning, you know, but it's not so clear that, hey, you get a bunch of microplastics and the next day you're depressed.
other than the number one environmental toxin of course out there drew that is just lurking uh totally destroying america's health which is alcohol and that that certainly is the number one environmental toxin that if they're for all of the talk of microplastics and mercury and mold and all this other stuff it's like no the number one problem in america when it comes from toxins or comes to toxins is certainly alcohol it's just um a bane on our society
Yeah. You know, I want to talk about nutrition a little bit more. What would you say if I told you let's design a diet that induces depression in somebody and also increases their risk of Alzheimer's, other neurodegenerative diseases, what would that diet look like? There is one type of sweetener that I've always felt great about using and never felt guilty about using, and that is honey.
And the kind that I use is called Manu Kora honey. It isn't your average grocery store honey. Manu Kora is next level. It's rich, creamy, insanely delicious, and it's packed with powerful bioactives that support immunity and gut health, which is great for cold and flu season.
Just a little teaspoon of honey in the morning coats my throat and gives me a powerful dose of antioxidants and prebiotics to help me keep my defenses super boosted. Manucora has three times more antioxidants and prebiotics than regular honey. It also contains MGO, a powerful antibacterial compound from the nectar of the manuka tree.

It would look a lot like the diet that some people are eating on an average day of American food. You wake up and you, first of all, you're going to have caloric excess. You're going to have some breakfast cereal, maybe low-fat yogurt, you know, might still be in that kind of low-fat, trying for low calories, but not eating really satiating foods kind of mindset.
There is gonna be a lot of processed food, right? So you're gonna experience a lot of intense flavors, a lot of sweetness, a lot of saltiness, this nice palatability of fats and sugars. The rest of the day could be some snacking, some ultra-processed food, some fast food, a nice burger and fries. It's a great study that came out, Drew, a couple of years ago now about fried foods.
And the people who eat the most fried foods had an increased correlational risk of anxiety. This is a large UK biobank study. And it was kind of showing what some of the new nutritional psychiatry studies are looking like, where they find this correlation. And then the researchers are like, huh, what is it about Western food that makes people have more anxiety?
And they said, oh, they're the signal in fried foods. And so they created an animal model. It was a zebrafish model where they found they took acrylamide, which is this byproduct when you make French fries. Especially when things get like really charred. Yeah, exactly. Acrylamide is a byproduct of this mallard reaction in time for sort of heating up fats and proteins.
And so acrylamide to these zebrafish ended up really disrupting their behavior. Zebrafish tend to pull together. They'd be curious and they'd kind of go explore stuff. When they'd put new things in the tank, the zebrafish would just kind of move around chaotically. They wouldn't pull together.
And the researchers kind of took this as an indication that, huh, it seems like these are more anxious, more depressed zebrafish. They don't want to partner together. They don't want to explore. They're not as confident. They don't want to work together and connect. So who knows? But a lot of fried foods.
And when you compare that, what is a French fry compared to an oven roasted potato or even a potato in an air fryer? When you oven roast a potato with some olive oil, you reduce acrylobide by 90%, 95% in the data I've seen. So that's an example. Lots of fried food, you're going to probably start to get a little schlumpy, so let's hit you with a few energy drinks in the afternoon.

Chapter 8: How does politics influence healthcare in America?
I feel, yes. I feel that we're not maybe talking of how bad it is. I guess I feel more that on an individual level, we're having a hard time taking individual actions today. I think that in healing the modern brain, I get into the first tenet of self-awareness and I get into the notion of externalization. And what you're talking about is, I think, true.
That we are set up that the cheapest calories, right, are the worst for us. That just to get by and feed your family, boy, when you do something that, in my mind, as a parent and as a physician, is a nice move in the beginning of the day, which is to have some eggs. You know, and until recently, that's been a pretty economical move. A dozen eggs used to be five bucks.
That's filled with controversy for a lot of people. The idea that you're going to go and again, have a simple 70 calorie egg, perfect protein, nice way to start the day.
What's controversial about that?
Well, I think controversial is that this is traditionally a food that's been thought to be high cholesterol or high saturated fat that tend to be avoided. I think that Eggs were one of those foods that's always been kind of lambasted, right, in a certain way in the science. Eggs are also one of those foods that I think everyone should always be suspicious if all of us are only citing one study.
What study besides the heart avert egg study does anyone talk about when it comes to eggs and risk? Until recently, there weren't really any. And then as we get a little bit more mature data about including eggs in the diet, I think the most recent data, they look pretty good. And so, so I'll just say, you know, are we being set up? I think so.
And in a certain way, that's where some of the motivation for this book comes from is to get out of that stance a bit and think about, you know, how are you contributing to that? Are you walking into Walmart and buying garbage? Are you walking into Walmart and buying wild salmon, pesto, anchovies, kefir? All the best brain foods are right there. I don't mean to mention Walmart. It could be Costco.
It could be any big box store. But the idea that, you know, the setup... I think the setup in part is misinformation and lack of knowledge. And then I think the setup in part, and we see this so often, I love these inspirational stories. I see this all the time in my practice where people can take control of their health. They do. It radically shifts. You aren't eating plants.
You start eating more plants, more fermented foods. Your health starts to shift. Almost always when people do one of these tenets, you start moving your body a little bit more. It's almost you can't do that without starting to care more about your nutrition. Boy, once you care about your nutrition and you're moving your body more, you're going to probably sleep better tonight, is my guess.
