The foods and beverages that people consume have a profound impact on their health. The scientific connection between food and health has been well documented for many decades, with substantial and increasingly robust evidence showing that a healthy lifestyle—including following a healthy dietary pattern— can help people achieve and maintain good health and reduce the risk of chronic diseases throughout all stages of the lifespan: infancy and toddlerhood, childhood and adolescence, adulthood, pregnancy and lactation, and older adulthood. The core elements of a healthy dietary pattern are remarkably consistent across the lifespan and across health outcomes.
Since the first edition was published in 1980, the Dietary Guidelines for Americans have provided science-based
advice on what to eat and drink to promote health, reduce risk of chronic disease, and meet nutrient needs.
Publication of the Dietary Guidelines is required under the 1990 National Nutrition Monitoring and Related
Research Act, which states that at least every 5 years, the U.S. Departments of Agriculture (USDA) and of Health and Human Services (HHS) must jointly publish a report containing nutritional and dietary information and guidelines for the general public. The statute (Public Law 101-445, 7 United States Code 5341 et seq.) requires that the Dietary Guidelines be based on the preponderance of current scientific and medical knowledge. The 2020-2025 edition of the Dietary Guidelines builds from the 2015 edition, with revisions grounded in the Scientific Report of the 2020 Dietary
Guidelines Advisory Committee and consideration of Federal agency and public comments.
The Dietary Guidelines is designed for policymakers and nutrition and health professionals to help all individuals and their families consume a healthy, nutritionally adequate diet. The information in the Dietary Guidelines is used to develop, implement, and evaluate Federal food, nutrition, and health policies and programs. It also is the basis for Federal nutrition education materials designed for the public and for the nutrition education components of USDA and HHS nutrition programs. State and local governments, schools, the food industry, other businesses,
community groups, and media also use Dietary Guidelines information to develop programs, policies,
and communication for the general public.
The aim of the Dietary Guidelines is to promote health and prevent disease. Because of this public health orientation, the Dietary Guidelines is not intended to contain clinical guidelines for treating chronic diseases. Chronic diseases result from a complex mix of genetic, biological, behavioral, socioeconomic, and environmental factors, and people with these conditions have unique health care requirements that require careful oversight by a health professional. The body of scientific evidence on diet and health reviewed to inform the Dietary Guidelines is representative of the U.S. population—it includes people who are healthy, people at risk for diet-related chronic conditions and diseases, such as cardiovascular disease, type 2 diabetes, and obesity, and some people who are living with one or more of these diet-related chronic illnesses.
At the same time, it is essential that Federal agencies, medical organizations, and health professionals adapt the Dietary Guidelines to meet the specific needs of their patients as part of an individual, multifaceted treatment plan for the specific chronic disease.
