Learn About the Process
The Dietary Guidelines for Americans, 2025-2030 (Dietary Guidelines) is being developed using a scientifically rigorous, multi-year process. The U.S. Department of Health and Human Services (HHS) and the U.S. Department of Agriculture (USDA) are committed to providing clear information to the public and providing opportunities for public participation during the process. Visit this page to learn more about the Dietary Guidelines development process.
2025 Scientific Report
The Scientific Report of the 2025 Dietary Guidelines Advisory Committee was submitted to the Secretaries of HHS and USDA and provides the Committee’s review of the current state of nutrition science and includes independent, evidence-based advice for HHS and USDA to consider as the departments develop the next edition of the Dietary Guidelines. The Scientific Report will be a key resource in developing the Dietary Guidelines for Americans, 2025-2030. Use the buttons below to explore the scientific advice found in the Scientific Report and supplement documents, and view past meetings where the Committee discussed their scientific review.
Examine the Evidence
To develop its Scientific Report, the Committee used three approaches to examine the evidence: Data analysis, systematic reviews, and food pattern modeling. Each of these approaches has its own rigorous, protocol-driven methodology, and played a unique, complementary role in examining the science. Use the buttons below to explore each of these approaches.
Get Involved
HHS and USDA have provided multiple opportunities for public participation before, throughout, and after the 2025 Dietary Guidelines Advisory Committee’s review of the science, and the departments value everyone’s engagement.
