Nutrition policies govern many aspects of the food system impacting food choices and prices in outlets such as grocery stores, restaurants, and schools, thus affecting what we eat. 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 provide services to children and families with the goal to increase food security and reduce hunger. Research in this area includes evaluating the impacts of nutrition programs and policies on diet quality and overall health, as well as exploring innovative approaches to improve program reach, participation and implementation.
