On the other hand, in Asian and Far Eastern areas where a majority of reported intakes ranged from 1,000 to 2,500 I.U., clinical vitamin A deficiency occurred in parts of the populationAccording to surveys in Latin America, carried out by national nutrition institutes and organizations, 72 percent of the localities surveyed had average intakes under 3,000 I.U. per person per day, and 15 percent, under 1,000 I.U. When standards of estimated requirements or allowances were applied, 46 percent of the localities and 54 percent of the individual families had less than 50 percent of the estimated requirements. In 66 percent of the localities, pre-formed vitamin A was under 30 percent of the totalAccording to the Interdepartmental Committee on Nutrition for National Defense (ICNND) surveys in South American and Caribbean areas, 60 percent of the localities surveyed had intakes under 3,000 I.U. per person per day, and 26 percent, under 1,000 I.U.
