Summary

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: Why chronic disease rates are skyrocketing—and how profit-driven systems are quietly fueling the epidemic The surprising truths (and myths) behind viral health debates like raw milk, Tylenol, and the MAHA movement How the U.S. food system prioritizes corporate profits over public health—and what that means for your grocery cart What the MAHA movement gets right about wellness—and where it completely misses the mark 👇 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?

0:00.0	Chronic disease rates have risen. People don't feel good. What are the reasons for that?
0:05.4	In the United States, what you'll find is that there's various systems that impact our health.
0:11.7	We have our food system. We have our built environment. We have our education systems. And all of these different kind of social determinants of health.
0:19.4	What you'll find is that most of these systems were built for corporate profits at the expense of our health. It's not necessarily
0:25.8	to make people unhealthy. It's just that that wasn't the primary value for corporations. The
0:30.9	primary value is profitability and growth. So in the simplest terms, what are the real root causes
0:36.1	of chronic disease in this country?
0:38.3	A lot of people will ask me, like, what's the number one thing you would do if you had a magic wand
0:41.9	and you could just, like, improve the health of Americans? And I always go to campaign finance,
0:46.2	and I think that it throws a lot of people off. Hi, I'm Jessica Nurek. I have a PhD in nutrition science,
0:51.3	and I'm a registered dietitianian and I've worked in chronic disease prevention
0:54.7	for about a decade and a half.
0:57.3	Chronic disease rates have risen. People don't feel good. What are the reasons for that?
1:02.6	You know, I got into this field a long time ago because of I wanted to study chronic disease
1:07.8	and I wanted, there was a chronic disease. We had seen rising
1:10.9	rates of chronic disease and I wanted to study why and how we could help to prevent that and
1:15.3	reduce risk. And what I found when I was studying is that we actually had pretty good data on
1:22.3	the lifestyle strategies to reduce risk of chronic disease. What was wrong was that people weren't adopting
1:27.9	those evidence-based strategies. And so that really got me thinking about like, oh, well, how could we
1:33.5	kind of, you know, I started studying what we called like the minimum effective dose that we could
1:38.5	have somebody do that would be kind of like something that could change and reduce their risk.
1:43.4	Once you start thinking about
