More than 100 medical, nutrition, and science experts have signed an open letter urging the Office of Management and Budget to release a formal definition of ultraprocessed foods. The request comes as a central promise of Health Secretary Robert F. Kennedy Jr.'s "Make America Healthy Again" agenda remains stalled at the White House.

Why is a federal standard needed?

A national standard would give policymakers, businesses, and families a shared reference point. Currently, a patchwork of state-level policies relies on differing definitions, which can confuse manufacturers and retailers. A single federal definition could assist in several areas:

  • Setting clearer guidelines for school meal programs.
  • Enhancing transparency on consumer food packaging.
  • Helping retailers and manufacturers understand regulatory expectations.

According to the CDC, ultraprocessed foods account for roughly 55 percent of the average American's daily calories, with even higher consumption among youth aged one to 18. Researchers have linked these products to increased risks of cardiovascular disease, obesity, and type 2 diabetes.

What is stalling the process?

The Department of Health and Human Services and the FDA submitted a proposed definition for review in August, but the rollout has faced significant resistance. Reports indicate food industry executives pushed back, citing concerns over legal liabilities and potential business costs. The Consumer Brands Association has argued that a new definition could raise food prices, a claim some researchers dispute.

Tension escalated with the resignation of Calley Means, a senior adviser to Kennedy and a prominent MAHA voice. While Means did not cite the definition as his reason for leaving, his departure has deepened frustration among advocates who believe corporate interests are slowing public health progress.

What happens next?

The Food is Medicine Institute at Tufts University, led by cardiologist Dariush Mozaffarian, is scheduled to meet with the Office of Management and Budget to present the petition. According to Mozaffarian, HHS hopes to release the definition before the upcoming midterms to demonstrate action to independent and swing voters.

FAQ

Does this definition impose new rules on food companies?

Experts say releasing the definition would not create new requirements for manufacturers or retailers, but would instead establish a shared baseline for public discussion.

Why does the definition matter for consumers?

A clear standard helps people better understand what they are eating, which is vital given that ultraprocessed products are linked to various long-term health issues.
