ReThink Health with Dr. Autumn Smith

IN THIS EPISODE

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

• What Dr. Berg's regenerative beef testing revealed about omega-3s, inflammation markers, phytonutrients, and metabolic health

• How keto and intermittent fasting may support weight loss, mood, energy, blood sugar, and metabolic health

If you've ever wondered how modern food production affects human health, this episode offers a thought-provoking look at the connection between agriculture, metabolism, and wellness.

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!

Most of us assume supplements are helping us.

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

• The difference between correlation and causation in nutrition research

• How soil depletion and modern agriculture may contribute to nutrient deficiencies

• Simple ways to evaluate supplement quality using better questions and tools

If you've ever wondered whether what you're taking is actually helping your health, this episode will completely change how you think about supplements

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)

• Why vilifying fat backfired — and what matters most instead

• How insulin resistance can make you hungrier and less motivated to move

• Why meat isn't the villain… but quality absolutely matters

• The "Goldilocks" approach to longevity: mTOR, autophagy, and realistic fasting windows

• What Dr. Hyman considers the most impactful rule of thumb for eating well

• Why personal responsibility alone is a broken framework in a highly addictive food environment

If you've ever felt like you're "doing everything right" and still not losing weight, this conversation will help you understand what's really going on… and give you a way forward that feels sane, practical, and empowering.

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.

• 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.

It's easy to think that skin issues are just cosmetic… something to cover up, manage, or ignore.

But what if your skin is actually one of the earliest warning systems in your body?

In this episode of the ReThink Health Podcast, I sit down with microbiologist Kiran Krishnan to explore a groundbreaking (and often overlooked) connection:

Your skin health may predict your risk for chronic disease, inflammation, and even how you age.

Drawing from decades of microbiome research, Kiran explains why conditions like acne, eczema, dryness, and sensitivity may be signs of deeper dysfunction. And more importantly, he reveals what you can actually do about it!

You'll learn:

• How "leaky skin" and barrier dysfunction may contribute to chronic disease risk

• The surprising link between skin issues and conditions like Alzheimer's, osteoporosis, and inflammation

• How the skin microbiome controls pH, hydration, and structural integrity

• What most skincare routines get wrong (and how they may be making things worse

• The connection between gut health, acne, and systemic inflammation

• Why certain everyday products (like soaps, fragrances, and makeup) may disrupt your skin's natural balance

• The role of probiotics, postbiotics, and microbial signaling in repairing the skin

• Simple, evidence-based ways to support your skin barrier naturally

If you've ever struggled with breakouts, dryness, sensitivity, or felt like your skin issues never fully resolve…

This episode will completely change how you think about your skin and your health.
