Grass Fed Beef Has 3x More of This Critical Nutrient (Shocking Results) with Dr. Stephen van Vliet

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.

Is sugar really "as addictive as cocaine"… or is that just clickbait? In this episode of the ReThink Health Podcast, I sit down with neuroscientist and nutrition researcher Dr. Nicole Avena to settle the debate using what the science actually shows (and chat about why her findings have sparked so much controversy!). We break down what researchers mean when they talk about "addiction-like" behavior with sugar, why ultra-processed foods are designed to keep you coming back for more, and what happens in your brain when you binge on sugar day after day. Most importantly, Dr. Avena shares practical, doable first steps to cut back without feeling like you're white-knuckling your way through life, starting with the two biggest needle-movers that make everything easier. You'll learn: Why sugar can trigger addiction-like brain changes (and when it doesn't) How sugar impacts dopamine differently than most foods and why that matters for cravings Why most people are binging on sugar without realizing it Why "natural" sweeteners like fruit juice concentrate can still be a metabolic trap The hidden sugar clue to look for on labels  The 2 simplest places to start cutting back on sugar How to manage cravings when they hit (and how to tell when you're actually hungry) Why sugar overconsumption affects mood, focus, and mental health, not just weight and blood sugar If you've ever wondered whether fasting is actually safe, effective, or "for you," this episode will help you understand the science and find a rhythm that supports your energy, metabolism, brain, and hormones.

How did Lucky Charms end up scoring "healthier" than eggs on the Tufts Food Compass, and what does that say about modern nutrition advice? If you've ever found yourself confused by food nutrient rankings like this, this episode is for you. In this episode, I sit down with Dr. Ty Beal, a global nutrition researcher known for bringing real nuance to the most polarizing food debates (animal foods, ultra-processed foods, vegetable oils, saturated fat… yes, all of it!). Ty breaks down what nutrient density actually means, why micronutrient deficiencies are far more common than most people realize (even in high-income countries), and why we can't "fortify our way" out of poor diet quality. He also explains the thinking behind his global nutrient-density rating system, built around the nutrients people are most likely to be missing, and adjusted for bioavailability. You'll learn: Why "quick energy" foods can look healthy on paper… while leaving your body undernourished The surprising prevalence of micronutrient deficiencies—and why they matter for energy, cognition, and long-term health What most nutrient-rating systems miss (and why ultra-processed foods can score absurdly high) The top nutrient-dense foods to keep stocked in your kitchen Why the food matrix matters, and why fortified nutrients aren't equivalent to nutrients in whole foods Ty's balanced take on saturated fat, red meat, and the often-unspoken truth about nutrition science A practical look at what Ty actually eats to optimize nutrient density (without being dogmatic) If you're tired of black-and-white nutrition advice and want a smarter, more grounded way to think about food quality, this episode will help you cut through the noise and focus on what actually supports long-term health.

Fasting gets talked about a lot… but most people still don't understand why it works or how to do it in a way that actually feels sustainable (especially if you're a woman navigating stress, hormones, and a busy life). In this episode of the ReThink Health Paleo Podcast, I'm joined by fasting expert Dr. Mindy Pelz, who breaks down the science in a way that's clear, empowering, and surprisingly doable. We talk about why your body has two fuel systems, how fasting helps you switch between them, and what starts to happen in the body at key milestones like 13–15 hours, 17 hours, 24 hours, and beyond. You'll also learn why fasting can feel amazing for some people, terrible for others, and how to train your body to fast safely instead of forcing it. Most importantly, Dr. Mindy shares practical ways to get started, plus how women can fast in a way that sustainably supports their hormones. You'll learn: Where the fasting sweet spot window is for autophagy, your body's cellular "cleanup mode" The incredible benefits of fasting for up to 24 hours  Why some people experience a "fasting high"  Why women may need to fast differently depending on where they are in their cycle How to start if you "can't fast" (and why you may have experienced issues in the past) Simple strategies to ride out hunger waves without white-knuckling Other easy ways to support autophagy beyond fasting If you've ever wondered whether fasting is actually safe, effective, or "for you," this episode will help you understand the science and find a rhythm that supports your energy, metabolism, brain, and hormones.

IN THIS EPISODE What if there was a rampant nutrient deficiency accelerating your aging, cranking up inflammation, and quietly sabotaging your health? Not a vitamin, or mineral, but a "nonessential" amino acid that was once abundant in our diets, but is largely missing today.  This isn't some fringe theory—it's what new research has been showing about an amino acid called glycine, a missing link to metabolic health, deeper sleep, stronger joints, calmer mood, smoother skin, and even a longer life.  That's why we invited Dr. Joel Brind—biochemist, longtime researcher, and author of The Glycine Miracle—onto the Optimize Paleo Podcast.  For decades, Dr. Brind has studied amino acids and uncovered surprising truths about protein.  We often hear that more protein is always better—but the type of protein also  matters and in this conversation, we dig into the science of glycine's profound benefits (especially for inflammation), the myths, and the practical ways to close the "glycine gap" for better health at any age. Listen in and tag someone in the comments who you think could benefit from this important information.

INSIDE THE EPISODE There's a common, often overlooked, dietary imbalance that may be increasing the risk of obesity, heart disease, pain, and mental health issues. That imbalance lies in the type of fats we consume, or the essential omega-6 (think seeds oils) and omega-3 (think fish and leafy greens) fats. While our ancestors evolved with a balanced ratio, today we consume about 20x more omega 6 fatty acids which many experts, like this week's podcast guest, Dr. Simopoulos, a world authority on essential fatty acids and former nutritional adviser to the White House, believes it is responsible for our skyrocketing rates of disease.  So in this week's podcast we'll explore how this imbalance crept into our modern diets, why it's driving so many of today's chronic health issues, and what you can do to turn it around. If you've ever wondered why inflammation, brain fog, and fatigue are so common—or why omega-3s are considered essential—this episode is for you! Dr. Simopoulos unpacks... The surprising sources of omega-6 overload The importance of prostaglandins (and what they are!) The powerful benefits of omega-3s for your brain, heart, and longevity And the simple steps you can take to restore balance and feel your best. It's a fascinating look at how something as seemingly small as a ratio can have such a profound impact on your health.  So grab your favorite snack, tune in, and learn how to eat for optimal health!
