The New Dietary Guidelines Controversy — Explained

The 2025–2030 Dietary Guidelines introduced changes that have caused confusion, disagreement, and strong reactions across nutrition and public health. In this episode of Daily Value, we walk through what actually changed, what didn’t, and why, explaining the evidence standards, policy constraints, and scientific disagreements that shaped the guidelines. The goal isn’t to tell you what to eat, but to help you understand how national nutrition policy is made, and why this cycle looks different from those before it.
