"The United States has played a leading role in global efforts to alleviate hunger and improve food security. Current food assistance programs originated in 1954 with the passage of what is now named the Food for Peace Act (FFPA, P.L.83-480). This legislation, commonly referred to as 'P.L. 480,' established the Food for Peace program (FFP). Originally, FFP had multiple aims: (1) to provide food to undernourished people abroad, (2) to reduce U.S. stocks of surplus grains that had accumulated under U.S. Department of Agriculture (USDA) commodity support programs, and (3) to expand potential markets for U.S. food commodities. Since the end of the Cold War, U.S. food assistance goals have shifted away from the latter two aims and more toward emergency response and supporting recipient country agriculture markets."
