Review of U.S. Nutrition Assistance Policy: Programs and Issues: This AGree backgrounder was written by Stephanie Mercier, former chief economist for the Senate Agriculture Committee. It provides a detailed and comprehensive overview of the domestic nutrition programs, such as the Supplemental Nutrition Assistance Program (SNAP) and National School Lunch Program, that are now the dominant components of U.S. agriculture policy from a budgetary standpoint. In addition to explaining the origins, characteristics, and impacts of the major programs, the backgrounder highlights current policy issues about their funding and operations.
