The recently released 2015-2020 Dietary Guidelines for Americans (DGA) 1 serves as our nation's nutrition policy backbone and an essential resource for health and nutrition professionals. Registered dietitian nutritionists (RDNs) rely on the evidence-based recommendations to help the public they serve make informed food and beverage choices. Now in its eighth edition, the DGA function as a roadmap to guide Americans ages 2 years and older in preventing diet-related health conditions like obesity, type 2 diabetes, heart disease, and some cancers. The DGA are also used in developing federal food, nutrition, and health policies and programs and serve as the basis for federal nutrition education materials for the public. Produced by the US Department of Agriculture (USDA) and US Department of Health and Human Services, the DGA are updated every 5 years to reflect advancements in scientific knowledge and to translate the current science into food-based guidance to promote health in the United States.
