In an unprecedented move, Senator Chuck Grassley last week called for suspending the work of the 2025 U.S. Dietary Guidelines for Americans until members of the expert committee in charge of the science fully disclose their conflicts-of-interest (COI).
This is potentially a huge win for greater transparency in the Dietary Guidelines, a battle that the Nutrition Coalition has led almost single-handedly for years. We supported the first-ever systematic review of COI on a Dietary Guidelines Advisory Committee (DGAC), which led to the revelation that 95% of the 2020 DGAC had at least one tie to the food/pharmaceutical industry. Before that, we were responsible for encouraging Congress to mandate the first-ever outside peer-review of the Guidelines, by the National Academies of Sciences, Engineering and Medicine (NASEM), which led to a recommendation for full public disclosure of all COI on the DGAC. This formal NASEM recommendation now provides the backing needed for Senator Grassley to make this request.
The Department of Agriculture (USDA) did recently release COI disclosures on its current expert committee, but as Grassley’s letter explains, “these disclosures were aggregated and not attributed to individual committee members.” This is contrary to basic disclosure practices, in which COI are listed by specific name.
Dr. Gordon Guyatt, a professor at McMaster’s University and one of the world’s leading experts in evidence-based medicine, commented, “If the USDA is trying to convey the message that they have something to hide and are doing their best to hide it, they are doing an excellent job.”

Our work was covered by “Food Navigator” in a piece entitled, “Dietary Guidelines Advisory Committee needs to be ‘free of food industry commercial interest." We’re glad this issue is finally receiving the coverage it deserves.
Senator Grassley’s letter asks for a response from USDA and the Department of Health and Human Services by June 8th.
