We compared nutrient intakes estimated from the 4th revised edition of the Standard Tables of Food Consumption in Japan with those estimated from the 5th revised edition. The influence of revision in the Standard Tables of Food Composition on nutrient intake was examined. 2110 men and women aged 40-82 years were studied. Nutrient intakes were calculated from the 4th edition using data on food intake in a 3-day dietary record. Nutrient intakes were then recalculated using the 5th food code converted from the 4th food code. Mean differences and mean percentage difference between nutrient intakes calculated from the 4th and the 5th ranged from -2.1 mg (-16%; iron) to 1132 micro g (31%; carotene), and these differences were significant for all nutrient intakes except protein and retinol. Coefficients of correlation between the nutrient intakes estimated from the 4th and the 5th ranged from 0.934 (carotene) to 0.996 (energy and protein), which were highly significant. However, regression analysis showed a significant systematic error in the nutrient intakes estimated from the 4th and the 5th code.
