Is Processed Meat Really Bad for You? with Dr. Frederick Leroy.
ReThink Health with Dr. Autumn Smith
IN THIS EPISODE 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. Frederick 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...

Grass-Fed Beef Has 3x More of This Critical Nutrient (Shocking Results) with Dr. van Vliet.
ReThink Health with Dr. Autumn Smith
IN THIS EPISODE 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...

Is Your Bad Mood Actually a Nutrient Deficiency? with Julia Ross.
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. ...

Can Eating Meat Actually Be Healthy? with Dr. Drew Pinsky
ReThink Health with Dr. Autumn Smith
IN THIS EPISODE 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,...

The Glyphosate Problem Nobody's Talking About (Can Glycine Fix it?) with Dr. Stephanie Seneff.
ReThink Health with Dr. Autumn Smith
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,...

Is Modern Food Making Us Sicker? with Dr. Eric Berg
ReThink Health with Dr. Autumn Smith
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...

Rethinking Saturated Fat and Healthy Aging with Dr. Stephanie Venn-Watson
ReThink Health with Dr. Autumn Smith
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...

The Supplement Industry Is Lying To You with Robyn Openshaw - Green Smoothie Girl
ReThink Health with Dr. Autumn Smith
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...

The Real Reason You Can't Lose Weight | It's Not What You Think (Dr. Hyman reveals)
ReThink Health with Dr. Autumn Smith
IN THIS EPISODE 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...

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.

BIO
Dr. Philip Calder is a Professor of Nutritional Immunology at the University of Southampton whose research explores how nutrition influences immune function, inflammation, and human health.
With a background in metabolic biochemistry, Dr. Calder began studying how immune cells use fatty acids nearly four decades ago. His discovery that different fatty acids could actually change the way immune cells function helped lead him into the emerging field of nutritional immunology. Today, his research focuses extensively on the effects of dietary fats (particularly omega-3 fatty acids) on immunity, inflammation, and health.
