Learn About the Process
The Dietary Guidelines for Americans, 2025-2030 (Dietary Guidelines) is developed using a scientifically rigorous, multi-year process. The U.S. Departments of Health and Human Services (HHS) and Agriculture (USDA) are committed to providing clear information to the public and providing opportunities for public participation during the process.

2025 Dietary Guidelines Advisory Committee
HHS and USDA appointed 20 nationally recognized experts to serve on the 2025 Dietary Guidelines Advisory Committee (Committee). The independent Committee will review scientific evidence on the topics and questions related to nutrition and health and provide a report on their findings to the Secretaries.
The Committee is examining a list of prioritized scientific questions, informed by the proposed list of scientific questions identified by HHS and USDA. The scientific questions guide the Committee’s evidence review on nutrition and health from birth through older adulthood.
Examine the Evidence
The Committee uses three approaches to examine the evidence: Data analysis, food pattern modeling, and systematic reviews. Each of these approaches has its own rigorous, protocol-driven methodology, and plays a unique, complementary role in examining the science.
