Revising the Food Guide Pyramid

摘要

The Food Guide Pyramid was initially introduced in 1992 to help Americans use the Dietary Guidelines for Americans (USDA, 1992) as a basis to choose foods for a healthy diet. In addition to its uses by nutrition educators, teachers, and the media, itis commonly used by the food industry on food packaging, marketing materials, and advertising to show the contribution of specific food products to an overall healthy diet. The advance of nutrition research, evidence for the benefits of individualized diets, and the development of Dietary Reference Intakes (DRIs) f or nutrients have all made it necessary to revise and update the pyramid.
