The International Atomic Energy Agency (IAEA), an organization within the United Nations (UN) system, is the world's central intergovernmental forum for scientific and technical cooperation in the nuclear field. The Nutritional and Health-related Environmental Studies (NAHRES) Section, part of the Division of Human Health (NAHU), enhances countries’ capabilities to combat malnutrition for better health throughout life. It complements the work of other UN agencies, non-governmental organizations and interested stakeholders in the field of nutrition and health by encouraging the use of accurate nuclear techniques to design and evaluate interventions aimed at addressing malnutrition in all its forms.

For example, NAHRES supports the application of stable isotopes to measure micronutrient bioavailability and vitamin A status, changes in body composition and physical activity, and infant feeding practices. The support mechanisms of the IAEA include Coordinated Research Activities (CRA) and the Technical Cooperation (TC) Programme.?
