- Federal agencies and governance: Secretaries must notify congressional committees 90 days before updates, can publish reports every 10 years or sooner, and must form a temporary Independent Advisory Board of up to 8 experts to submit priority scientific questions.

Bill Overview
Analyzed Economic Effects
4 provisions identified: 3 benefits, 0 costs, 1 mixed.
Faster updates to nutrition references
If enacted, the Secretaries would coordinate with the U.S.-Canada Dietary Reference Intake Working Group. The bill would push the National Academies' Food and Nutrition Board to update Dietary Reference Intake values to reflect current science. The Working Group would be encouraged to start at least one DRI update per year and to identify high-priority updates that need review.
New rulemaking and update schedule
If enacted, the Secretaries would publish Dietary Guidelines at least every 10 years. They would use public rulemaking for each update under 5 U.S.C. 553. The Secretaries could update sooner if new Dietary Reference Intake values or science justify it. The 2020 Guidelines would remain the most recent until a new report is published. The Secretaries must notify four named congressional committees in writing at least 90 days before an update and explain why they plan an update.
New advisory board, conflict rules
If enacted, the Secretaries would set up a temporary Independent Advisory Board within 90 days after giving the 90-day notice. The Board would have up to 8 members with nutrition or food science expertise. Six members would make a quorum and the Board must give a list of scientific questions within one year, then end. People appointed to the Board or the Advisory Committee would file full OGE Form 450 disclosures. The Secretaries would publish those disclosures and a plan to manage any conflicts within 30 days. The bill would also require strict evidence-based reviews, outside peer review, and strength-of-evidence ratings for each guideline. Secretaries, with the Board, could exclude topics they deem irrelevant, including taxation, federal feeding purchases, food production, labeling, socioeconomic status, race, religion, ethnicity, and culture.
Funding for guideline updates
If enacted, the Secretary of Agriculture would make $5,000,000 available each year for fiscal years 2025 through 2029. The money would come from section 32 funds and would remain available until spent. The funds would help carry out the amended Dietary Guidelines authorities.
