Nuclear and isotopic techniques application used in supporting nutritional studies in Latin America countries

The global nutrition community recognizes the usefulness of nuclear and isotopic techniques and especially stable isotopes for accurate measurements in key areas of human nutrition and health. Although progress has been made in many Latin America countries in reducing the absolute number of undernourished people, food policy and public health communities have to face the double burden on health. On one side they have to address the prevention of obesity and on the other side they are trying to reduce undernutrition. However, to be successful in development of sustainable nutrition programs, a combination of relevant scientific knowledge and approaches that are practical is required to assure even a reasonable level of success. The objectives of this review are to highlight the role of isotopic techniques in nutritional studies and to review the role of the International Atomic Energy Agency in supporting nutrition interventions in Latin America countries.
