Nutrition Assistance for Puerto Rico or NAP is a federal assistance nutritional program provided by the US Department of Agriculture (USDA) solely to the Commonwealth of Puerto Rico, a self-governing dependency of the United States. It provides over $1.5 billion in supplemental economic resources to help just over 1 million impoverished residents cope with their nutritional needs. The program is commonly known in Puerto Rico as Programa de Asistencia Nutricional, or PAN, or Cupones. It is based on, though not directly part of, the USDA`s national Food Stamp Program.
