MyPyramid, released by the USDA Center for Nutrition Policy and Promotion on April 19, 2005, was an update on the earlier American food guide pyramid.
Significant changes from the previous food pyramid include: MyPyramid was designed to educate consumers about a lifestyle consistent with the January 2005 Dietary Guidelines for Americans, an 80-page document.
The guidelines, produced jointly by the USDA and Department of Health and Human Services (HHS), represented the official position of the U.S. government and served as the foundation of Federal nutrition policy.
MyPyramid was intentionally made simpler than the food guide pyramid after several USDA studies indicated that consumers widely misunderstood the original design.
