School food service programs such as we have in 1971 did not just happen over-night nor even during the past decade. Preceding today's programs is a long history of more than a hundred years of development, of testing and evaluating, and of constant research to provide the best in nutrition, nutrition education, and food service for the nation's millions of children in school.
The Low-Cost, Moderate-Cost, and Liberal Food Plans outline nutrient-dense foods and beverages, their amounts, and associated costs that can be purchased on three successively higher budgets, each supporting a healthy diet through nutritious meals and snacks at home. The Low-Cost, Moderate-Cost, and Liberal Food Plans are used by various federal and state agencies and the court system.
The Thrifty Food Plan, a fundamental part of the U.S. food guidance system and the basis for maximum food stamp allotments, has been revised by USDA’s Center for Nutrition Policy and Promotion, with assistance from USDA’s Food and Nutrition Service, Economic Research Service, and Agricultural Research Service. The TFP provides a representative healthful and minimal cost meal plan that shows how a nutritious diet may be achieved with limited resources. The plan assumes that all purchased food is consumed at home.
