The Academy of Nutrition and Dietetics is a 501(c)(6) trade association in the United States. With over 112,000 members, the association claims to be the largest organization of food and nutrition professionals. It has registered dietitian nutritionists (RDNs), nutrition and dietetics technicians registered (NDTRs), and other dietetics professionals as members. Founded in 1917 as the American Dietetic Association, the organization officially changed its name to the Academy of Nutrition and Dietetics in 2012. According to the group's website, about 65% of its members are RDNs, and another 2% are NDTRs. The group's primary activities include providing testimony at hearings, lobbying the United States Congress and other governmental bodies, commenting on proposed regulations, and publishing statements on various topics pertaining to food and nutrition.

The association is funded by a number of food multinationals, pharmaceutical companies, and food industry lobbying groups, such as the National Confectioners Association. The Academy has faced controversy regarding corporate influence related to its relationship with the food industry and funding from corporate groups such as McDonald's, Coca-Cola, Mars, and others.
