The 2025 Dietary Guidelines have settled in, but are they helping people eat healthier?

We talk about why fiber deserves way more attention than protein, how food industry interests can shape nutrition policy, and why a whole-food plant-based diet continues to stand on solid scientific ground.
If you've ever wondered whether nutrition advice is driven by science or something else, this conversation will help you cut through the noise.
In this episode, we talk about:
- How the food industry's influence shapes nutrition recommendations
- Why protein gets all the attention while fiber is often overlooked
- What the research really says about saturated fat and long-term health
- How whole plant foods naturally provide the nutrients your body needs
- Why a low-fat, whole-food plant-based diet is the way to go
- Why social media nutrition trends aren't always backed by evidence
- Simple ways to make food choices based on science instead of hype
