Physicians Committee sues US government over food industry influence in dietary guidelines

The Physicians Committee for Responsible Medicine has filed a lawsuit against the US government, calling to withdraw the 2025–2030 Dietary Guidelines for Americans released in January this year. The committee argues that the government’s “secret panel” had industry links, therefore, making the guidelines biased. 

The lawsuit alleges that the nation’s Department of Health and Human Services (HHS) and the US Department of Agriculture (USDA) picked food industry insiders to form a “secret panel” to illegally influence dietary recommendations under the national guideline. The lawsuit was filed on August 19 this week in the District of Columbia.

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

The association claims that the guidelines prioritize fats, meat, and dairy, which contradicts earlier independent advisory committee recommendations that called for increasing plant-based foods, shocking many health experts. Some praised the guidelines for giving more recognition to dietary supplements. 

The guidelines were also welcomed by industry and health organizations, but criticized for their questionable scientific basis and ideological undertones.

Researchers pointed out a lack of clarity on alcohol, with the guidelines saying “limit alcohol” without quantifying it, arguing that concrete thresholds are needed to convey real risk.

While pointing out a conflict of interest among the panel members, the Physicians Committee seeks to replace the current guidelines with new ones that adhere to legal standards.

Overriding DGAC recommendations

The Physicians Committee says that the scientific foundation for the guidelines was quickly assembled by consultants with financial links to the meat, dairy, and low-card industries, which the organization says did not follow the recommendations made by the Dietary Guidelines Advisory Committee (DGAC).

The DGAC is made up of 20 independent nutrition experts who write scientific reports to serve as the foundation for the dietary guidelines, which the HHS and USDA issue every five years — a process falling under the Federal Advisory Committee Act (FACA).

However, the Physicians Committee says the HHS and USDA “disregarded federal law through a procedural bait and switch” after the publication of the December 2024 Scientific Report of the 2025 DGAC. The report recommended that the guidelines advise Americans to consume more plant-based foods, prioritize beans, eat more plant proteins than animal proteins, and prioritize water over milk.

Instead, the Physicians Committee claims that the current guidelines replaced DGAC’s recommendations, a result of a transparent public process with industry insiders without oversight or public input.

The nonprofit’s recent survey revealed that many Americans are misguided about what healthy food is. Its poll found that one in five US adults does not know diet affects cholesterol, and many wrongly believe chicken and lean red meat are heart-healthy.

Lawsuit arguments

According to FACA, the advisory committee cannot be “inappropriately influenced” by the appointing authority or by other special interests. 

However, the Physicians Committee points to a conflict of interest from eight of the nine members of the secret panel. These members had ties to the National Cattlemen’s Beef Association, the National Dairy Council, the American Egg Board, the National Pork Board, and the low-carbohydrate diet industry, it adds.

Previously, Nutrition Insight spoke to Barnard, who called for balanced industry involvement when creating dietary guidelines. He petitioned in a JAMA publication that the 2025–2030 Dietary Guidelines for Americans be withdrawn.

Additionally, the lawsuit notes that the secret panel took a short time to produce its report — 90 pages with a 418-page appendix — only made available along with panel names on the day the dietary guidelines were published.

“The 2025–2030 Dietary Guidelines pose dangers to children, whose school food programs must adhere to the Dietary Guidelines; to individuals with medical conditions who might follow the baseless medical advice incorporated into the Dietary Guidelines; and to Americans who are at risk for diet-related diseases, including obesity, diabetes, and cardiovascular disease, and might follow the scientifically unfounded Dietary Guidelines, which are designed to promote fatty, high-cholesterol products of industries with which the Dietary Guidelines’ authors are affiliated,” argues the lawsuit.

The lawsuit requests that the HHS and USDA withdraw the current guidelines while creating another one compliant with the FACA.

“Industry-influenced Dietary Guidelines destroy any semblance of healthfulness in federal food programs like the National School Lunch Program; Special Supplemental Nutrition Program for Women, Infants, and Children; and Supplemental Nutrition Assistance Program,” comments Barnard.

Previous challenges

This is not the first time that the Physicians Committee has sued the government for its publication of the dietary guidelines. 

It says it previously argued on the 2000 issuance that six of the 11 DGAC members had financial ties to the meat, dairy, or egg industries, and that these links increase the chance that unhealthy foods would remain in the dietary guidelines. 

A federal court had reportedly agreed that the government violated both laws.

The nonprofit also previously challenged the dietary guidelines in 2010, 2015, and 2020 in federal court.
