Dietary intake of some essential micronutrients in China.
OBJECTIVE
Based on the data collected in the 1992 national nutrition survey in China, the food consumption and nutrients intake were calculated, and the consumption of some micronutrients was evaluated.


METHODS
Dietary data were obtained by using a three days' inventory change plus food weighing in combination with 24 hours recall method for three consecutive days. The food consumption and nutrients intake were calculated in accordance with the Chinese food composition table. The consumption of some micronutrients was evaluated in reference to the Chinese RDAs.


RESULTS
The average intakes of niacin, ascorbic acid and vitamin E were sufficient, whereas that of zinc, selenium and thiamin were between 80% and 90% RDAs. The consumption of calcium, retinol equivalent and riboflavin was low compared with the Chinese RDAs. Calcium was the most insufficient nutrient in Chinese diet.


CONCLUSIONS
Food fortification seems necessary for improving the nutritional status of some micronutrients in China.
