Science and Evidence-Based Nutrition Information You Can Trust
Our mission at the Academy of Nutrition and Dietetics is to support and elevate the profession of registered dietitian nutritionists (RDNs) and nutrition and dietetics technicians, registered (NDTRs), while also improving the nutritional status for all.
Misinformation about nutrition is widespread and it’s more important than ever to rely on science and evidence-based expertise. The Academy is committed to taking on the uncredentialed and unqualified individuals giving nutrition advice by opening more doors for Academy members to be heard by decision-makers and consumers. We are proud to amplify the voices of credentialed practitioners and help ensure that evidence-based nutrition and health science shapes public health policy debates, media narratives and consumer choices.
This hub is your go-to source for credible, research-backed insights that help dispel misinformation and ensure nutrition policies and recommendations are rooted in science.
Every March, the Academy hosts National Nutrition Month® as a way to elevate the role of RDNs and NDTRs as experts in food and nutrition; educate the public by providing evidence-based information on nutrition, meal planning and healthy eating habits; encourage healthful lifestyle changes; and address diverse dietary needs and cultural food traditions to make healthy eating accessible to all.
This year, National Nutrition Month® means more as we are going on the offensive against misinformation and uninformed opinions by promoting science-based nutrition. Access and share these resources:
