Dietary Guidelines Reform Act of 2025

The Dietary Guidelines Reform Act of 2025 was introduced by Sen. Marshall (R-KS) on March 25, 2025, and referred to the Senate Committee on Agriculture, Nutrition, and Forestry. As of April 30, 2026, the bill remains in early stage with no hearings, markups, or floor votes. The bill would amend the National Nutrition Monitoring and Related Research Act of 1990 to lengthen the dietary guideline update cycle from 5 years to 10 years, impose rulemaking requirements under the Administrative Procedure Act, and shift the evidence standard to 'significant scientific agreement.' The bill authorizes no spending and contains no mandatory funding provisions. There is a companion bill in the House (HR2326), but both remain stalled at the referral stage. Because the bill is purely procedural—it changes how guidelines are developed and updated but does not mandate any specific dietary recommendations, create subsidies, impose taxes, or authorize procurement—there are no direct revenue or cost implications for any publicly traded company. Food and beverage companies, agricultural producers, and supplement manufacturers would only be affected if the guidelines themselves changed, which this bill does not do. The bill's early stage and lack of fiscal impact justify the low impact score.
