In the United States, the Supplemental Nutrition Assistance Program (SNAP), formerly known as the Food Stamp Program, is a federal government program that provides food-purchasing assistance for low- and no-income people to help them maintain adequate nutrition and health. It is a federal aid program administered by the U.S. Department of Agriculture (USDA) under the Food and Nutrition Service (FNS), though benefits are distributed by specific departments of U.S. states.
