Summary
The 2025 US Dietary Guidelines are out, and they’ve sparked debate across the nutrition world. In this episode, I sit down with Dr David Katz to examine where the new recommendations align with science and where they diverge from the Dietary Guidelines Advisory Committee’s evidence review. We discuss the increased emphasis on meat and protein, contradictions around saturated fat and full-fat dairy, the controversy around seed oils, and what everyday people should actually focus on. What We Cover Why David believes science was subordinated to ideology The protein recommendation: do most Americans need more? Meat versus legumes for long-term health Saturated fat limits and whether the guidelines contradict themselves Full-fat dairy: beneficial, neutral, or harmful? Seed oils, essential fats, and common misconceptions The role of fibre and what gets displaced when protein increases The simple dietary pattern most associated with longevity Despite the noise, one principle remains consistent: eat real food, mostly plants, in balanced combinations. The fundamentals of good nutrition have not changed. You can connect with Dr David Katz on LinkedIn, Facebook, and X (Twitter).
