The Gale Encyclopedia of Diets: A Guide to Health and Nutrition
The Dietary Guidelines for Americans are the foundation of national nutrition policy for the United States. They are designed to help Americans make food choices that promote health and reduce the risk of disease. The guidelines are published jointly by the U.S. Department of Agriculture (USDA) and U.S. Department of Health and Human Services (HHS). The first set of guidelines was published as in 1980. Since then, an advisory committee has been appointed every five years to review and revise the guidelines based on the latest research in nutrition and health.
