Abstract: 1. Dietary intakes of magnesium (Mg), zinc (Zn) and copper (Cu) were estimated by means of food composition table (FCT) -based calculation, and the values thus obtained (the calculated values) were compared with the values measured by the inductively coupled plasma atomic emission spectrometry (ICP-AES) (the measured values). The calculated values were all lower than the measured values, and were considered to be inadequate for the estimation of dietary element intakes. 2. Not all of the food items consumed were listed in the FCT. The weights of the food items consumed that were listed in the FCT were summed up (FCT-SUM), and the sum was compared with the weight of total food items consumed (CONSUMED). The measured values were corrected by multiplying the ratio of CONSUMED/FCT-SUM (the corrected values, or the values corrected on a total food basis). The corrected values were 116,116 and 117% of the measured values in cases of Mg, Zn and Cu, respectively. The corrected values are related with the measured values in all three comparisons, although the correlation coefficients were all less than 0.5. 3. Further trials for obtaining a better correlation were made by classification of food items in terms of food groups after the ECT, followed by the correction for each food groups, and then summing up the corrected values. No improvement, however, could be achieved by this procedure. 4. It was concluded, therfore, that the correction on the total food basis would be recommended, and that rough estimates of Mg, Zn and Cu intakes should be available by this procedure.
