Nutrition and aging: potentials and problems for research in developing countries

The demographic explosion of persons over 60 years of age is a reality in developed and developing countries alike. There is evidence that research on aging and nutrition in Third World countries is growing and developing. Specific research programs, and the linking of these programs in timely multicenter efforts, promise both valuable descriptive research for the benefit of national populations and comparative insights that will help us to learn more, collectively, about the intrinsic nature of the aging process itself.
