Robert F. Kennedy Jr. pledged to establish a formal definition for "ultraprocessed" foods, but developing clear criteria has proven more challenging than anticipated. While experts agree that defining this food category would help guide Americans toward healthier eating choices, the complexity of food processing and the lack of consensus on specific parameters have delayed progress. The issue highlights broader difficulties in creating regulatory frameworks around modern food production methods.


A standardized definition of ultraprocessed foods could inform food labeling policies, dietary guidelines, and public health initiatives aimed at reducing consumption of foods linked to obesity, diabetes, and other chronic diseases. Without clear criteria, consumers and health professionals lack consistent guidance on which foods to limit or avoid.


A definition would help Americans eat healthier food, experts say. It’s turned out to be harder than expected
