Many questions have been generated from the comparison of nutrient intakes in developing countries to the recently revised U.S. Recommended Dietary Allowances and corresponding U.K. standards. Questions revolve primarily around the lowest levels nutrient intakes can reach before health, mental development, or growth are jeopardized. In light of overnutrition problems in some countries, it is possible that slower growth may be preferable. It is impossible for lactating mothers to achieve U.S. RDAs in Third World countries, yet almost 100% of these women lactate successfully. Calcium intakes of South African black mothers are about 25% of RDAs, yet satisfactory calcium homeostasis is maintained; black mothers experience one-tenth the number of hip fractures of white mothers. These apparent differences of nutrient requirement should be examined. Research should be directed toward determining the lowest levels of nutrient intake compatible with good health, as population increases continue to outstrip food production. (cj)
