Public Critique of the 2026 USDA Dietary Guidelines

Dr. Robert Lustig was invited onto the Dietary Guidelines Advisory Committee on August 4, 2025, by an HHS Assistant Secretary — with Lustig’s condition, he says, that Health Secretary Robert F. Kennedy Jr. have no involvement — and quit two days later, on August 6, when, he says, Kennedy “unilaterally pulled nine abstracts” for political reasons. The episode marks Lustig as a movement ally on food policy who is openly critical of RFK Jr. himself.

On the new six-page 2026 guidelines, released under the watchword “Eat real food,” Lustig says he supports two elements — limiting added sugar and limiting ultra-processed food — but argues that dietary guidelines change industry behavior, not consumer behavior, and that this edition lacks nuance. His recurring example: the guidelines fail to distinguish plain yogurt from strawberry yogurt, which he describes as ultra-processed by virtue of its added sugar.
