The American Dietary Guidelines , launched in early 2026, are a set of official recommendations created by the U.S. government and updated every five years.
It has a direct impact on the definition of public food policies, especially school meals and support for populations in situations of food insecurity.
Given its scientific relevance, its global impact, and the fact that this new guide presents some scientific contradictions and an unconventional graphic representation—an inverted pyramid—we decided to ask three professors from FCNAUP, from different areas, for a personal comment on this newly launched tool.
Each with their own style and without limits.
A contribution from the Nutrition Center to this necessary discussion.
Ada Rocha, Full Professor at FCNAUP
"In the Portuguese context, this guide does not appear to add value compared to the Food Wheel, which is widely validated and culturally appropriate."
Alejandro Santos, Associate Professor with Habilitation at FCNAUP
"From what can be read in the document, and in the numerous comments it has generated, I believe it is possible to conclude that it has positive, negative, and even incomprehensible aspects."
Pedro Moreira, Full Professor at FCNAUP
"In this context, and from the perspective of cardiovascular prevention, these guidelines are accused of, in some respects, doing the opposite of what was traditionally recommended."
