Nutrition and agriculture policies govern many aspects of the food that is grown domestically or imported from other countries, as well as federal nutrition assistance programs such as the Supplemental Nutrition Assistance Program (SNAP), the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), and the national school meal programs. These policies impact food choices and prices in outlets such as grocery stores, restaurants, and schools, thus affecting what we eat. Research in this area includes evaluating what impacts federal nutrition and agriculture programs and policies can have on diet and health.
