Linking nutrition surveys with total diet studies

Abstract

Intakes of major macro- and micronutrients were carried out in the Chinese TDS conducted between 1990 and 2000, (Part II, Chap. 5) based on the nutrient concentrations of the TDS samples. In comparison with results from the conventional dietary survey, the intake levels for macronutrients and minerals are generally comparable, but the intakes of water-soluble vitamins from TDS were lower due to cooking loss. Examples on copper intake in children, intakes of different forms of iron and cholesterol intake are provided. Nutritional assessment of diet by TDS could be an additional use of the TDS samples and provide valuable information on nutrients that are not available or complete in the food composition table. TDSs may also be useful to provide better information for some unstable nutrients and micronutrients than conventional dietary surveys.
