Dietary Guidelines for Americans
Purpose of the Dietary Guidelines
The U.S. Departments of Agriculture (USDA) and Health and Human Services (HHS) work together to update and release the Dietary Guidelines for Americans (Dietary Guidelines) every five years. Each edition of the Dietary Guidelines reflects the current body of nutrition science and provides advice on what to eat and drink to promote health and reduce risk of chronic disease. The 2015-2020 Dietary Guidelines for Americans is the current edition, and will remain so until the next edition is released.
In the U.S., more than half of all adults have one or more preventable chronic diseases, many of which are related to poor diets and not enough physical activity. Additionally, poor diets, tobacco use and not enough physical activity, among other risk factors, are leading causes of deaths in the U.S. Providing up-to-date nutrition advice through the Dietary Guidelines can help to improve the health of Americans by encouraging healthy food and beverage choices that are enjoyable, promote health, and help prevent chronic disease.
