What this bill does
In plain words · AI-written from the official summaryStricter rules for federal dietary guidelines
This bill changes how the government creates dietary guidelines, which are recommendations from the U.S. Department of Agriculture and Department of Health and Human Services about what Americans should eat. The guidelines would be updated less often (every 10 years instead of 5), must be based on strong scientific agreement rather than just general scientific knowledge, and must include an independent board of nutrition experts who disclose any financial conflicts of interest. The bill also says the guidelines can only focus on diet and health, not topics like taxation or farming practices.
How it affects you
If you follow dietary guidelines—whether to manage your health, make meal decisions, or as part of your job in nutrition or public health—you may see changes in what official recommendations say. School lunch programs, nutrition labels, and workplace wellness programs often rely on these guidelines, so updates could eventually affect those. For most people, the main change is that new guidelines would come out less frequently, so recommendations stay the same longer before being updated.

Dietary Guidelines Reform Act of 2025
This bill increases the requirements for the Dietary Guidelines for Americans (DGA). The DGA are federally developed recommendations by the Department of Agriculture (USDA) and the Department of Health and Human Services (HHS).
Under the bill, USDA and HHS must jointly publish guidelines at least once every 10 years (currently 5 years), and the final DGA is subject to rulemaking requirements.
The DGA must be based on significant scientific agreement that is determined by evidence-based review. Current law requires that the guidelines be based on a preponderance of current scientific and medical knowledge.
Further, the guidelines must address issues such as (1) high-priority areas to advance health outcomes, (2) achieving nutritional adequacy and promoting health, and (3) common nutrition-related chronic diseases.
In updating the guidelines, USDA and HHS must establish an Independent Advisory Board that must submit a list of scientific questions to be used as the basis for the proposed DGA. Members of the board must (1) have expertise in nutrition science or food science, and (2) disclose all relevant financial and nonfinancial conflicts of interest.
The bill prohibits the DGA from being based on or including topics that are not relevant to dietary guidance (e.g., taxation, social welfare policies, food and agricultural production practices, and race).
The bill provides specified funds through FY2029 to carry out these requirements.
Finally, the bill specifies that the 2020 DGA are the controlling guidelines until new guidelines are published in accordance with these requirements.
