Description
The Dietary Guidelines for Americans (DGAs) provide science-based recommendations to promote health, meet nutrient needs, and reduce the risk of chronic disease among Americans. Jointly developed by the U.S. Department of Agriculture and the U.S. Department of Health and Human Services, the DGAs guide federal, state, and community nutrition programs and inform nutrition education nationwide. First released in 1980 following earlier national efforts to address diet-related chronic disease, the Guidelines have been updated every five years since 1985 to reflect the evolving scientific evidence. The Dietary Guidelines Advisory Committee (DGAC), an independent panel of nationally recognized experts, plays a central role in this process by rigorously evaluating evidence through analyses of national datasets and systematic reviews. Public engagement and peer review further strengthen the transparency and credibility of the process. The recently released 2025–2030 Dietary Guidelines continue this evidence-based tradition, serving as a foundational framework for U.S. nutrition policy and public health efforts aimed at improving population health.
