Dietary guidelines form the basis for nutrition advice and regulations around the world. While there is strong scientific consensus around most existing guidelines, one question has recently stirred debate: Should consumers be warned to avoid ultra-processed foods?

Two papers published today in The American Journal of Clinical Nutrition (AJCN) outline the case for and against using the concept of ultra-processed foods to help inform dietary guidelines beyond conventional food classification systems. The authors, Carlos A. Monteiro, MD, PhD, of the University of São Paulo in São Paulo, Brazil, and Arne Astrup, MD, PhD, of Novo Nordisk Foundation in Hellerup, Denmark, will discuss the issue in a live virtual debate June 14 during NUTRITION 2022 LIVE ONLINE.
