Nutrition policy scholar Marion Nestle to speak March 19 | Cornell Chronicle

"Bottom line, these new guidelines represent a political message, not a scientific one. What raises red flags is when they are saying, 'Everything you ever knew about nutrition is wrong.' You have to roll your eyes."

"Critics, however, argue that the process departed from long-standing norms of scientific transparency and independence. The new guidelines not only set aside key recommendations from the administration's own independent scientific advisory committee, but also replaced the familiar MyPlate graphic with an inverted food pyramid emphasizing meat and full-fat dairy."

The 2025-2030 Dietary Guidelines for Americans have sparked controversy among nutrition scientists due to significant departures from scientific consensus and established processes. The new guidelines rejected key recommendations from the federal government's own independent scientific advisory committee and replaced the MyPlate graphic with an inverted food pyramid emphasizing meat and full-fat dairy. While supporters appreciate the guidelines' stance against ultra-processed foods and added sugars, critics contend the development process violated long-standing norms of scientific transparency and independence. Marion Nestle, a prominent food policy expert, characterizes the guidelines as a political message rather than a scientific one, noting the problematic nature of claims that established nutritional knowledge is fundamentally wrong.
