If you’ve ever felt like you’re doing everything “right” with your health but still not seeing results, this episode is for you. I sit down with Dr. Jessica Knurick, a PhD in nutrition science and registered dietitian with over 15 years of experience in chronic disease prevention, to uncover why Americans are getting sicker. Spoiler: it’s not just about diet or exercise—it’s about the systems shaping our lives in ways we don’t even realize. 

We dive deep into how our food environment, healthcare structure, and political systems were built for profit, not people, and how that reality quietly shapes everything from what ends up in our grocery stores to who can afford preventive care. 

We also tackle the viral health debates taking over social media—like the Make America Healthy Again (MAHA) movement, raw milk, and claims about Tylenol and autism—using the latest scientific research to separate fact from fiction. 

You’ll leave feeling empowered to take action not just in your own kitchen but in your community. 

🎧 What you’ll learn: 

👇 Reflect or share: What’s one health “truth” you’ve rethought after listening to this episode? I’d love to hear your take! 

✨ Homework: Pay attention to how your environment—what’s available, affordable, and marketed to you—shapes your health this week. Then ask yourself: If the system changed, how would your health change?
