The foo guide pyramid was the previous nutritional guide (created at Tufts University School of Medicine) of the USDA, replaced in April 2005 by the new USDA nutrition advisory program titled "MyPyramid".. The food guide pyramid was surprisingly not created with the involvement of the Department of Health and Human Services, which would be expected for most matters involving human health. This has resulted in criticism stating that the real purpose of the new recommendations is to improve the economic position of US grain producers and not the health of the population.
