ReThink Health with Dr. Autumn Smith

IN THIS EPISODE

What if your bloating, gas, or reflux had a deeper story to tell?

In this episode of the ReThink Health Podcast, I sit down with my dear friend Dr. Izabella Wentz, a pharmacist, bestselling author, and one of the most trusted voices in functional medicine for thyroid health. Her new book takes on a condition that affects millions of people and often leaves them without answers: irritable bowel syndrome, or IBS.

This topic is personal for both of us. Izabella was diagnosed with IBS in pharmacy school. Over time, her symptoms grew to include anxiety, hair loss, acid reflux, and joint pain, and she was eventually diagnosed with Hashimoto's.

I also struggled with IBS and was told it was stress, handed a few remedies, and wished good luck. Learning to work with food and digestion changed everything for me.

Izabella explains why an IBS diagnosis is a starting point, not an answer. Drawing on her training as a pharmacist and her work with thousands of clients, she shares why there's no one-size-fits-all IBS diet and why your symptoms are clues worth following. She also explains how an unhappy gut may be connected to issues far beyond digestion, from mood to autoimmunity.

You'll learn:

•

The many possible root causes of IBS, including infections, enzyme gaps, hormone imbalances, mold, and medications

•

Why some infections may linger long after a stomach bug or food poisoning seems to be gone

•

How H. pylori may set the stage for reflux, food sensitivities, and SIBO, plus a simple toothbrush tip to avoid reinfection

•

The surprising connection between vitamin B1 (thiamine) and digestion

•

How nickel sensitivity, including from cutlery and certain foods, may affect your gut

•

The food additives Izabella avoids most, including some common in "keto" snacks

•

Why some people react to raw vegetables, and what it may mean if you only feel good on a carnivore diet

•

The tests Izabella uses to uncover root causes, and how to think about food sensitivity testing

•

Simple mealtime habits and supplements Izabella uses to support digestion

If you've been told your digestive symptoms are "just IBS," this episode offers a new way to look for answers and better questions to bring to your healthcare provider.

What if one of the most widely accepted pieces of nutrition advice was never backed by solid evidence?

In this episode of the ReThink Health Podcast, I sit down with Nina Teicholz, investigative journalist and author of the New York Times bestseller The Big Fat Surprise. It's one of my favorite books. In fact, it was the first one I read that pulled together the full history of how saturated fat, animal foods, and vegetable oils came to be viewed the way they are today.

Nina wasn't always a critic of low-fat diets. She was a vegetarian for more than 20 years and struggled with her weight. When a magazine assigned her a story on trans fats, she began calling researchers and found that many were afraid to talk to her. That fear sparked nearly a decade of research and thousands of scientific studies.

In our conversation, Nina traces the story from the arrival of Crisco in 1911 to today's dietary guidelines. She explains how vegetable oils went from industrial byproducts to "heart-healthy" staples, how one charismatic scientist shaped national policy, and why large clinical trials that challenged that policy were left unpublished or ignored for decades.

You'll learn:

•

Why researchers have been afraid to question the low-fat, low-saturated-fat message, and what happens to those who do

•

The flaws Nina found in the Seven Countries Study, the main evidence behind early fat guidelines

•

The large clinical trial whose results went unpublished for 17 years, and what it found

•

What more than 20 recent scientific reviews have concluded about saturated fat and heart disease

•

How conflicts of interest may shape the committees that write national nutrition policy

•

The food rating system that scored sugary cereals higher than eggs and beef

•

What Nina believes the research shows about seed oils, oxidation, and inflammation

•

Why dietary cholesterol is no longer listed as a "nutrient of concern," and why most people never heard

If you've ever felt confused by conflicting nutrition advice, this episode will help you understand where it came from, and give you better questions to bring to your healthcare provider.

Is grass fed beef really worth the extra money? And how do you know you're getting what you pay for?

In this episode of the ReThink Health Podcast, I sit down with Dr. Lucas Krusinski, an assistant professor of animal science whose research looks at how farming practices change the nutrients in our food. I read many of his papers while preparing for my own dissertation on beef nutrient density, so this conversation has been a long time coming.

Dr. Krusinski explains why not all beef is created equal. He walks us through how a cow's diet, pasture diversity, and feed supplements can change the omega-3s and plant compounds that end up on your plate. He also shares findings from his newly published paper on a surprising gap in the food system: many labels promise better nutrition, but almost none actually test for it.

He even shares early results from a study in which he tested 40 brands of beef liver supplements. What he found may change how you shop for them.

You'll learn:

•

Why "grass fed" and "pasture-raised" labels may not tell you as much as you think

•

The one nutrient Dr. Krusinski would use to judge the quality of beef, and why

•

How a national survey found huge differences in the omega-3 content of beef that was all labeled "grass-finished"

•

The levers ranchers can pull to raise omega-3s in beef, including pasture diversity, hay, fermented forage, and flaxseed

•

What testing 40 beef liver supplements revealed about vitamin A, minerals, and quality

•

How eggs, chicken, and pork compare to beef when animals are raised on pasture

•

How Dr. Krusinski shops for beef, including the visual clues he trusts more than labels

Whether you're a conscious meat shopper or a rancher who wants to raise more nutritious food, this episode will help you look past the label to make more informed decisions.

IN THIS EPISODE What if we've been looking at cancer the wrong way for more than 70 years?

In this episode of the ReThink Health Podcast, I sit down with Dr. Thomas Seyfried, a professor of biology at Boston College and author of Cancer as a Metabolic Disease. For decades he has asked a question most of oncology stopped asking long ago: what if cancer isn't driven mainly by bad genes?

This conversation is deeply personal for me. My dad battled cancer three times, and I recently lost him. Two of my close friends, one in her 40s and one in his 50s, are facing cancer right now. Dr. Seyfried's work was a source of hope for our family, and I know cancer touches almost everyone's life.

Dr. Seyfried explains why he believes cancer is primarily a mitochondrial metabolic disease. His argument builds on the work of Nobel laureate Otto Warburg and on his own lab's research into how cancer cells rely on two fuels: glucose and glutamine. He walks us through the nuclear transfer experiments that challenged the gene-centered view of cancer. He also explains why cancer cells "ferment" for energy instead of "breathing" like healthy cells.

You'll learn:

•

Why Dr. Seyfried believes the gene mutations found in cancer are an effect of the disease rather than its cause

•

The difference between fermentation and respiration, and why cancer cells keep fermenting even when oxygen is present

•

Why he says glucose and glutamine must be targeted together, and how his "press-pulse" strategy works

•

How to use the Glucose-Ketone Index to see where your metabolism stands

•

Why ketones are often called a "super fuel" for healthy cells

•

How alcohol, portion size, exercise, stress, and fasting affect your glucose ketone index (GKI)

•

What forever chemicals and rising childhood obesity may mean for cancer rates in kids

•

What a day of eating and living looks like for a researcher who has studied cancer for 40 years

IN THIS EPISODE What if the most overlooked nutrient in your diet isn't a vitamin or a mineral, but a simple amino acid your body already makes?

In this episode of the ReThink Health Podcast, I sit down with Dr. Joel Brind, a biochemist with over 50 years in medical research and the author of The Glycine Miracle. Dr. Brind has spent nearly two decades studying glycine, and he makes the case that this "nonessential" amino acid may actually be the body's primary regulator of inflammation. Unfortunately, most of us are falling short by as much as 10 grams a day… which translates to a shockingly wide range of health problems today.

You'll learn:

•

Why glycine is technically "nonessential," and why your body likely can't make nearly enough of it on its own

•

Why meat eaters surprisingly have less glycine in their blood than vegans

•

How glycine acts as a molecular gatekeeper, controlling whether immune cells stay calm or launch a full inflammatory response

•

Which modern eating habits may be driving a glycine deficiency

•

Why higher natural glycine levels translate to a lower risk of major cardiac events

•

New research on how restoring glycine to aging cells can reverse markers of mitochondrial aging

•

Why Dr. Brind believes chronic, unresolved inflammation after everyday injuries like sunburns or sprains isn't actually "normal"

•

The difference between getting glycine from food, collagen, magnesium glycinate, or a standalone supplement, and what each does and doesn't provide

•

Practical, everyday ways to close the "glycine gap" without overhauling your entire diet

If you've ever wondered why nagging aches, poor sleep, or slow recovery seem to be your "normal," this conversation offers a compelling, science-backed reason why they might not have to be.

Are our brains shrinking? According to my guest this week, the answer is a resounding yes… and he's been warning us about it since 1972.

In this episode of the ReThink Health Podcast, I sit down with Dr. Michael Crawford, a pioneering nutritional scientist and one of the first researchers in the world to identify DHA (docosahexaenoic acid) as essential to brain development and function. Nearly 40 years ago, his lab discovered that primates deprived of omega-3 fatty acids developed severe self-harming behavior, hair loss, and psychological distress that reversed once DHA was restored to their diet.

Since then, the evidence has only grown. Dr. Crawford walks us through the astonishing story of how the human brain evolved in the sea over 500 million years, why larger-bodied animals are actually worse at making their own DHA, and why average human brain capacity is rapidly shrinking.

We also get into the controversial and often misunderstood topic of mercury in seafood, why pregnant women may be doing more harm than good by avoiding fish, and what groundbreaking new research is revealing about DHA's role in brain development before birth.

You'll learn:

•

Why brain tissue is fundamentally different from the rest of the body, and why government nutrition guidelines miss this entirely

•

The staggering economic cost of brain disorders, and why it now outpaces heart disease and cancer combined

•

The real reason ultra-processed foods are stripped of omega-3s, and why that matters more than you might think

•

The truth about mercury in seafood, and why its "danger" is far less significant than we've been told

•

What Japan's coastal restoration projects can teach us about rebuilding our own fisheries and food systems

•

The best food sources of DHA, including surprising picks for people who don't eat fish

If you're not eating seafood on a regular basis, this episode makes a compelling case for why that one change could matter more than almost anything else you do for your brain.

Is your morning coffee helping or hurting your health?

The answer may depend on much more than how many cups you drink.

In this episode of the ReThink Health Podcast, I sit down with nutritional biochemist Stephen Cherniske, author of Caffeine Blues, for a nuanced look at one of the most widely consumed compounds in the world: caffeine. Rather than labeling caffeine "good" or "bad," Stephen explains why your dose, timing, genetics, and individual response can completely change how caffeine affects you.

Stephen (who still drinks coffee himself) encourages understanding your own physiology and using caffeine strategically rather than mindlessly; a distinction that becomes especially important since people can metabolize and respond to caffeine very differently.

You'll learn:

•

Why caffeine doesn't actually give your body energy (and what it does instead)

•

The research-backed benefits of caffeine for cognition, memory, athletic performance, and metabolic health

•

Why the same amount of caffeine may make one person feel great and another anxious, jittery, or unable to sleep

•

How caffeine can interfere with deep, restorative sleep even when you think you're sleeping just fine

•

How your heart rate and sleep quality may provide clues about your personal caffeine tolerance

•

Why caffeine timing matters (and when Stephen recommends cutting yourself off for the day)

•

Why tea may feel different from coffee for people who are sensitive to caffeine

•

What to look for when choosing a high-quality decaf coffee

If coffee is one of the first things you reach for every morning, this episode will help you stop thinking about caffeine as simply "healthy" or "unhealthy" and start asking a much more useful question: How is it actually affecting you?

Most of us hear the words "processed meat" and immediately think unhealthy.

But is a traditionally fermented salami really the same thing as an ultra-processed meat snack packed with sugar, fillers, and additives?

In this episode of the ReThink Health Podcast, I sit down with Dr. Frederic Leroy, a professor and food scientist who has spent decades studying animal-source foods, fermentation, food processing, and human nutrition.

Dr. Leroy explains why lumping every processed meat into one category misses some important details. (Humans have been drying, curing, smoking, and fermenting meat for thousands of years, and traditional products can look very different from modern ultra-processed versions!)

It's a refreshingly nuanced conversation that moves beyond "processed meat = bad" and asks a much more useful question: What kind of processing are we actually talking about?

You'll learn:

•

The difference between traditionally processed and ultra-processed meat products

•

What the WHO's processed-meat classification actually tells us about hazard vs. risk

•

Why much of the processed-meat research relies on observational data, and why that matters

•

How traditional fermentation, curing, drying, and smoking preserve meat

•

How to spot a higher-quality processed meat by reading the ingredient list

•

What nitrates and nitrites actually do in cured meats (and why celery-derived nitrate is still the same molecule)

•

What we know (and don't know) about probiotics, postbiotics, and bioactive peptides in fermented meats

•

Dr. Leroy's simple framework for building a nourishing diet without following rigid food rules

If you've been avoiding ham, salami, jerky, or meat sticks because you've heard that all processed meat is unhealthy, this episode will help you understand the important differences that rarely make it into nutrition headlines.

You've probably heard that omega-3s are good for you. But few people realize just how crucial they are for brain health, inflammation, and so much more… and just how many of us aren't getting enough.

In this episode of the ReThink Health Podcast, I sit down with Dr. Philip Calder, Professor of Nutritional Immunology at the University of Southampton and one of the world's leading researchers on omega-3 fatty acids and inflammation.

According to Dr. Calder, an estimated 75% of people worldwide aren't getting enough EPA and DHA, the omega-3s most strongly linked to human health. And over time, low omega-3 status may contribute to greater risk of cardiovascular disease, metabolic disease, cognitive decline, and other conditions associated with aging.

Come explore why DHA is especially important for the brain, how omega-3s may support muscle as we age, the nuanced truth about omega-6 seed oils, and simple ways to improve your omega-3 status through food and supplements.

You'll learn:

•

How omega-3s change your cell membranes and influence how your cells function

•

How EPA, DHA, and DPA literally help turn off inflammation

•

Why DHA plays a unique role in the brain, vision, and cognitive function

•

The difference between EPA and DHA (and why you need both)

•

How omega-3s may support muscle protein synthesis and healthy aging

•

The surprising connection between omega-3s, fertility, pregnancy, and infant development

•

Why the balance between omega-6 and omega-3 fatty acids matters

•

The best food sources of EPA and DHA, and how much Dr. Calder recommends getting each day

•

How the Omega-3 Index can help reveal your long-term omega-3 status and future health risks

If you're not regularly eating fatty fish, there's a good chance you're missing out on these critical fats. This episode explains exactly why omega-3s matter and the practical steps you can take to get more of them.

We love to argue about food like it's simple—grass-fed vs. grain-fed, animal vs. plant, protein powder vs. "real food." But the truth is… we're barely scratching the surface of what food actually contains.

In this episode of the ReThink Health Podcast, I sit down with Dr. Stephen Van Vliet (Utah State University), a researcher on the front lines of nutrient density, metabolomics, and regenerative agriculture. His lab is helping answer the questions most of us feel are important, but don't have clear, evidence-based answers for yet:

•

Does food quality actually change what happens in your body?

•

Does the way an animal is raised matter… beyond marketing labels?

•

And what does "nutrient-dense" even mean when a food can contain thousands of compounds we don't track on a nutrition label?

You'll hear why beef may contain tens of thousands of unique metabolites, how new metabolomics tools are changing what we can measure, and why "grass fed" isn't always as straightforward as people think. Dr. van Vliet also shares fascinating early findings from long-term human trials, looking at what happens when people switch from conventional to pasture-raised animal foods, including changes in omega-3 levels in the blood.

It's a nuanced, science-forward conversation that skips the dogma and gets to what really matters: making food choices that support real health over the long haul.

You'll learn:

•

Why nutrition labels only tell a tiny part of the story

•

What "nutrient density profiling" really means (and how it's measured)

•

Why whole foods can act differently in the body than isolated protein powders

• The surprising reasons why some "grain-fed" samples can be more nutrient-dense than the least nutrient-dense "grass fed" samples
• What Dr. van Vliet's research suggests about omega-3s in pasture-raised meat, eggs, and blood markers over time
•

The emerging role of phytonutrients in animal foods (and why liver may be especially interesting)

•

The most impactful "health upgrade" you can make today

If you've ever felt skeptical of nutrition debates that sound too black-and-white, this episode will feel like a breath of fresh air and a glimpse into where food research is heading next.

When we feel anxious, down, or just not like ourselves, we usually assume something in our life is to blame.

But what if sometimes the problem isn't your life… it's that your brain is missing a crucial nutrient?

In this episode of the ReThink Health Podcast, I sit down with Julia Ross, a pioneer in the nutritional use of amino acids for mood, cravings, eating disorders, and addiction. After more than 40 years of clinical work, she's helping answer some fascinating questions about the connection between protein, brain chemistry, and how we feel.

You'll hear how amino acids like DLPA, GABA, tryptophan, tyrosine, and glutamine interact with neurotransmitter systems tied to mood and appetite. Julia also explains why cravings for foods like chocolate, sugar, bread, and cheese may offer clues about what's happening in the brain… and why getting enough high-quality protein is such an important nutritional foundation.

It's a fascinating look at mood and cravings from a completely different angle: not just what's happening in your life, but whether your brain has the raw materials it needs to function at its best.

You'll learn:

•

The difference between a "true mood" and a "false mood"

•

How specific amino acids support neurotransmitters involved in mood, calm, focus, and pleasure

•

Why DLPA may support endorphin activity and emotional well-being

•

How GABA, tryptophan, tyrosine, and glutamine each play different roles

•

Why certain food cravings may offer clues about your brain chemistry

•

How ultra-processed diets and low protein intake may affect amino acid availability

•

How to tell exactly which amino acids you need for your most vibrant health

If you've ever wondered why you can have a good life and still not feel good, this episode offers a fascinating new way to think about the connection between food, brain chemistry, and mood.

We're told meat is dangerous, fat is the enemy, and cereal somehow ends up with a better "health score" than beef or eggs. But what if much of that narrative is based on oversimplified science… and not the full picture of human biology?

In this episode of the ReThink Health Podcast, I sit down with Dr. Drew Pinsky to unpack his personal health transformation and what he believes is the powerful link between diet, inflammation, brain function, and long-term metabolic health. Drawing from decades in medicine and his own experience shifting to a low-carb, meat-forward diet, Dr. Drew explains why carbohydrates, ultra-processed foods, and unhealthy fats may play a far bigger role in mental and physical health than we've been led to believe.

You'll learn:

•

How a high carbohydrate intake may drive inflammation, insulin issues, and metabolic dysfunction

•

The incredible results and dramatic improvements Dr. Drew noticed in himself after reducing carbs

•

Why the brain is not separate from the body—and how diet impacts mental health directly

•

The potential role of red meat and amino acids in mood, focus, and overall well-being

•

Why ultra-processed foods and "yummy" engineered carbs can be habit-forming and disruptive to appetite regulation

•

The difference between wellness, mental health, and mental illness—and where nutrition fits in

•

Why reading labels and eating consciously may be the most powerful first step for lasting change

If you've ever felt confused by conflicting headlines about meat, fat, and carbs—or wondered how diet truly affects mood, energy, and long-term health—this episode offers a grounded, experience-backed perspective that cuts through the noise.

Glyphosate is one of the most widely used herbicides in the world.

But what if its impact on human health goes far beyond the plants it was designed to kill?

In this episode of the ReThink Health Podcast, Dr. Stephanie Seneff and I dive into one of the most controversial and fascinating theories in modern health: the possible connection between glyphosate, glycine, and chronic disease.

Glycine is an amino acid that plays a massive role in proteins, collagen, digestion, detoxification, immune function, and cellular repair. And according to Dr. Seneff's research, glyphosate's structural similarity to glycine may help explain why so many modern health issues are rising alongside increased glyphosate exposure.

In this eye-opening conversation, we explore how glyphosate may impact the gut microbiome, where it hides in the food supply, and why glycine-rich foods like bone broth, collagen, and fermented foods may help support resilience.

You'll learn:

•

Why glyphosate was marketed as "safe" for humans… and why that explanation may be incomplete

•

How glyphosate may disrupt the gut microbiome and contribute to digestive dysfunction

•

The unexpected connection between glyphosate and glycine

•

Which foods may contain the highest glyphosate residues, including a surprising category many people think of as healthy

•

How quickly glyphosate levels may drop when switching to an organic diet

•

Why fermented foods, sulfur-rich foods, and glycine-rich foods may help support the gut

•

What deuterium is and why Dr. Seneff believes it may play a role in mitochondrial dysfunction

If you've ever wondered why gut issues, food sensitivities, inflammatory conditions, and chronic disease seem to be rising so quickly… this episode offers a fascinating look at one possible missing piece.

What if the health of your food starts long before it reaches your plate?

In this episode of the ReThink Health Podcast, Dr. Eric Berg and I explore the fascinating connection between soil health, regenerative farming, nutrient density, metabolic health, and the ketogenic diet.

Dr. Berg shares his personal journey from being a self-described "junk food junkie" struggling with severe health issues… to discovering low-carb nutrition, healthy keto, and the powerful role food quality plays in long-term wellness.

But this conversation goes far beyond keto.

We dive deep into the modern food system, why regenerative farming may produce more nutrient-dense meat, how soil microbes influence plant and animal health, and why the quality of the food you eat may matter just as much as the macros.

You'll learn:

•

Why Dr. Berg says going vegan was "the sickest time" of his life

•

Why bioavailable nutrients like vitamin A, iron, zinc, DHA, and protein may be harder to obtain from plants alone

•

The difference between "healthy keto" and simply eating low carb

•

How soil health may directly influence plant, animal, and human health

•

The hidden problems with conventional agriculture, glyphosate, hormones, antibiotics, and grain-fed livestock

For decades, we've been told to avoid saturated fat.

But what if one specific saturated fat is actually essential for healthy aging?

In this episode of the ReThink Health Podcast, Dr. Stephanie Venn-Watson and I discuss a groundbreaking discovery that could completely reshape how we think about fat, aging, and metabolic health.

While studying aging Navy dolphins, Dr. Venn-Watson and her team uncovered something unexpected…

The healthiest, longest-living dolphins consistently had higher levels of a little-known fatty acid called C15:0 (pentadecanoic acid).

And researchers now believe C15 may qualify as the first newly discovered essential fatty acid in over 90 years since omega-3s were identified.

In this fascinating conversation, Dr. Venn-Watson explains how decades of low-fat dietary recommendations may have unintentionally lowered our intake of this critical nutrient. Plus, we cover what that could mean for rising rates of insulin resistance, fatty liver disease, accelerated aging, and metabolic dysfunction.

You'll learn:

•

What C15 actually is and why scientists are calling it a potential essential fatty acid

•

How dolphin research unexpectedly unlocked new insights into human aging and metabolic health

•

The surprising connection between low C15 levels, fragile red blood cells, iron overload, and accelerated aging

•

Why higher C15 levels are associated with lower risks of type 2 diabetes and cardiovascular disease

•

How modern low-fat dietary trends may have contributed to widespread C15 deficiency

•

Which foods naturally contain higher amounts of C15

•

The connection between C15, metabolic health, inflammation, liver health, and biological aging

•

What RDW (red blood cell distribution width) may reveal about aging and cellular health

If you've ever wondered whether all saturated fats deserve their bad reputation… or why rates of metabolic disease seem to be skyrocketing despite decades of low-fat advice… this episode has the answers!

After all… they're marketed as essential for filling nutrient gaps, supporting immunity, and optimizing health.

But what if that assumption deserves a closer look?

In this episode of the ReThink Health Podcast, I sit down with Robyn Openshaw (author, researcher, and founder of GreenSmoothieGirl) to pull back the curtain on the supplement industry.

What she uncovered after years of deep research may completely change how you think about the pills in your cabinet.

From synthetic vitamins to fish oil, collagen, and beyond, Robyn explains why not all supplements are created equal… and why many may not be delivering the benefits people expect. You'll learn:

•

Why most supplements on the market are synthetic (and what that actually means)

•

The surprising connection between the pharmaceutical and supplement industries

•

Why isolated nutrients may not replicate the complexity of whole foods

•

What's really behind common supplements like vitamin D, B12, and collagen

•

Why many fish oil supplements may be oxidized or ineffective

•

We've been told weight loss is simple: "Eat less and move more." And if you can't… it must be a willpower problem.

But Dr. Mark Hyman says this story doesn't match what we're seeing in real life… or what the science actually shows.

In this episode of the ReThink Health Podcast, I sit down with Dr. Hyman to unpack the real drivers behind stubborn weight gain (and why so many people feel like their body is working against them).

We talk about how today's food environment is built around ultra-processed, hyper-palatable ingredients that don't just add calories; they change your biology, disrupt appetite signals, and push the body toward insulin resistance and fat storage.

You'll also hear Dr. Hyman's grounded take on the "fat vs. carbs" debate, why food quality matters more than diet labels, and what simple shifts actually move the needle — without shame, extremes, or perfectionism.

You'll learn:

•

Why "calories in, calories out" doesn't explain stubborn weight gain

•

How ultra-processed foods can hijack hunger, energy, and cravings

•

The #1 dietary driver behind metabolic dysfunction (and why bread isn't "better" than sugar)

We're told meat is dangerous, fat is the enemy, and cereal somehow ends up with a better "health score" than beef or eggs. But what if much of that narrative is based on oversimplified science… and not the full picture of human biology?

In this episode of the ReThink Health Podcast, I sit down with Dr. Drew Pinsky to unpack his personal health transformation and what he believes is the powerful link between diet, inflammation, brain function, and long-term metabolic health.

Drawing from decades in medicine and his own experience shifting to a low-carb, meat-forward diet, Dr. Drew explains why carbohydrates, ultra-processed foods, and unhealthy fats may play a far bigger role in mental and physical health than we've been led to believe.

You'll learn:

• How a high carbohydrate intake may drive inflammation, insulin issues, and metabolic dysfunction
• The incredible results and dramatic improvements Dr. Drew noticed in himself after reducing carbs
• Why the brain is not separate from the body—and how diet impacts mental health directly
• The potential role of red meat and amino acids in mood, focus, and overall well-being
• Why ultra-processed foods and "yummy" engineered carbs can be habit-forming and disruptive to appetite regulation
• The difference between wellness, mental health, and mental illness—and where nutrition fits in
• Why reading labels and eating consciously may be the most powerful first step for lasting change

If you've ever felt confused by conflicting headlines about meat, fat, and carbs—or wondered how diet truly affects mood, energy, and long-term health—this episode offers a grounded, experience-backed perspective that cuts through the noise.

We tend to think of inflammation as something that just happens… a normal response to stress, aging, or injury. But what if much of today's chronic inflammation is actually a nutrient deficiency problem hiding in plain sight?

In this episode of the ReThink Health Podcast, I sit down with Joel Brind, a world-renowned biochemist and author of The Glycine Miracle, to explore why glycine (an amino acid long labeled "non-essential") may actually be one of the most critical and overlooked nutrients in modern diets.

Dr. Brind explains how glycine acts as the body's natural anti-inflammatory regulator, helping keep immune cells from overreacting, supporting healthy blood flow, calming the nervous system, and even protecting against inappropriate clotting. He also reveals why most people today are unknowingly deficient, thanks to diets high in muscle meats and low in collagen-rich foods like bones, connective tissue, and skin.

You'll hear how glycine plays a central role in managing inflammation, sleep, cardiovascular health, immune balance, and recovery… and why simply eating "enough protein" isn't the same as getting the right balance of amino acids.

This is a deep, science-forward conversation that challenges long-held nutrition assumptions and offers a clearer framework for supporting long-term health from the inside out.

You'll learn:

•

Why glycine is your body's built-in anti-inflammatory "trigger lock"

•

How chronic inflammation may stem from glycine deficiency, not just stress or aging

•

The sneaky reason why modern diets high in muscle meats drain glycine reserves

•

How glycine helps regulate immune cells, blood clotting, and vascular inflammation

•

Why glycine supports better sleep, recovery, and nervous system balance

•

The surprising links between glycine, cardiovascular risk, and plaque formation

•

Why bone-based foods like collagen and bone broth matter more than most people realize

•

Practical ways to increase glycine intake through food and supplementation

If you've ever felt confused by inflammation advice that focuses only on avoiding foods or suppressing symptoms, this episode offers a refreshing, biology-based perspective on what your body actually needs to stay resilient.
