Physicians Committee sues US government over 2025-2030 Dietary Guidelines

The Physicians Committee for Responsible Medicine has filed a federal lawsuit seeking the withdrawal of the 2025-2030 Dietary Guidelines for Americans, alleging that the US government bypassed federal transparency requirements and allowed an industry-linked panel to influence their scientific basis.

• The Physicians Committee filed suit against HHS and USDA, alleging that an undisclosed panel improperly influenced the 2025–2030 Dietary Guidelines for Americans.
• The complaint alleged that eight of the panel’s nine members had conflicts involving meat, dairy, egg or low-carbohydrate diet industry interests.
• The organization asked the court to order the guidelines withdrawn and prevent their use in agency decisions while a legally compliant process is undertaken.

Filed with the US District Court for the District of Columbia on August 19, the lawsuit challenges the process used by the Department of Health and Human Services (HHS) and US Department of Agriculture (USDA) to develop guidelines released on January 7, 2026.

The Physicians Committee argues that the agencies departed from the established Dietary Guidelines Advisory Committee process and instead relied on recommendations developed by a separate group of consultants whose identities were not disclosed until the guidelines were published.

“The government allowed the meat and dairy industries to ghostwrite the Dietary Guidelines,” said Physicians Committee President Neal D. Barnard, MD (main picture). “They put money in industry’s pocket and cholesterol in Americans’ arteries.”

Dietary Guidelines for Americans are issued every five years by HHS and USDA and influence federal nutrition policy and programs including school meals.

Ahead of each edition, the agencies establish a Dietary Guidelines Advisory Committee (DGAC), whose scientific report informs the eventual recommendations.

For the 2025-2030 edition, a 20-member DGAC completed a two-year public process and published its scientific report in December 2024. Among its recommendations were greater consumption of plant-based meals, placing beans and other plant-based protein sources ahead of animal proteins, and making water rather than milk the preferred beverage.

The Physicians Committee alleges that HHS and USDA subsequently engaged in what its complaint describes as a “procedural bait and switch”, departing from those recommendations and drawing instead on work from another nine-member panel.

According to the complaint, that panel completed a 90-page report and 418-page appendix in approximately three months. The report, appendix and identities of its members were made public on January 7, the same day as the final Dietary Guidelines.

The Physicians Committee alleges that eight of the nine members had conflicts of interest involving organizations including the National Cattlemen’s Beef Association, National Dairy Council, American Egg Board and National Pork Board, as well as interests connected with low-carbohydrate diets.

Its legal challenge centers on the Federal Advisory Committee Act (FACA), which governs the operation of federal advisory committees and includes requirements intended to protect their independence from appointing authorities and special interests.

The organization argues that the additional panel effectively performed an advisory role without the transparency and public oversight required under the Act.

The resulting 2025–2030 Dietary Guidelines place greater emphasis on meat, dairy and fats than the earlier DGAC recommendations, according to the Physicians Committee.

The organization also raised concerns about the consequences for federal nutrition programs and people who follow the guidelines when making dietary decisions.

“Industry-influenced Dietary Guidelines destroy any semblance of healthfulness in federal food programs like the National School Lunch Program, WIC, and SNAP,” Barnard said.

The lawsuit asks the court to order HHS and USDA to withdraw the current Dietary Guidelines and prohibit their use in future agency decisions while new guidelines are developed through a process compliant with FACA.

The case is the latest legal challenge brought by the Physicians Committee over the development of federal dietary advice.

Before publication of the 2000 Dietary Guidelines, the organization sued under FACA and the Freedom of Information Act over alleged financial ties between members of the advisory committee and the meat, dairy and egg industries. A federal court subsequently found that the government had violated both laws.

The Physicians Committee also brought challenges relating to the 2010, 2015 and 2020 editions of the Dietary Guidelines.
