Episode 476: The Upside-Down Pyramid of the USDA Guidelines

This week, Dr. Kahn breaks down the newly released USDA 2025–2030 Dietary Guidelines and the surprising upside-down food pyramid they present. He explains how the final report differs from last year's Advisory Committee recommendations, including changes in committee membership and the influence of advisors with financial ties to the meat and dairy industries. Looking back at the original 1980 dietary guidelines, Dr. Kahn asks an important question: how much has really changed? His takeaway remains refreshingly simple—eat food, mostly plants, not too much. Short topics this week include urinary measurements of protein intake, optimal timing for surgery in dilated aortic roots, the cardiovascular risk of lipoprotein(a), and whether the science behind the Blue Zones truly holds up.
