Abstract: A referencee text for professionals involved in supplemental feeding programs and food and nutrition policy in developing countries reports the results of 4 major nutrition projects (Indonesia, Brazil, Colombia, India) carried out in collaboration with the World Bank, and discusses over 50 nutrition components that have been incorporated into the design of agricultural, urban development, and health projects. It is concluded that, while malnutrition is associated with the status of a country's economic development, major, cost-effective nutritional interventions can be effected prior to major economic advancement through thoughtful allocation of food subsidies and nutrition education to those at greatest nutritional risk. Nutrition research and analyses supported and conducted by the World Bank also are discussed.
