[Dietary intake of some micronutrients in different provinces of China].
Based on the data collected in 1992 China National Nutrition Survey, which covered 100,201 persons of all ages in 29 provinces, the dietary intakes of some micronutrients were calculated. The intake of calcium, retinal equivalent and riboflavin were the most insufficient nutrients; zinc, selenium and thiamin were close to (80%-90%) of Chinese RDAs. The intakes of niacin, ascorbic acid and vitamin E were sufficient. The regions in the northeast, northwestern and the southeastern inland were more at risk of nutrition deficiency. Dietary intervention or food fortification with some micronutrients could be used for improving the situation.
