Abstract
This study aimed to clarify the influence of revision of the Food Composition Database in Japan on estimated nutrient intakes, those estimated from the 6th revised edition were compared with those estimated from the 7th revised Supplementary edition 2018. Nutrient intakes were estimated using one-day food intake data from 625 participants in Hokkaido and Tokyo. The nutrient profile of food intakes was calculated using two editions of the Japanese Standard Food Composition Tables (6th revised edition and 7th revised Supplementary edition 2018). The differences in the Food Composition Tables were responsible for significant differences in nutrient intakes excluding carbohydrates. Total dietary fiber intake, for which values had been updated, was significantly impacted.The intake value for the 7th revised Supplementary edition 2018 was 3.0 g (23.2％), being higher than the intake value for the 6th revised edition. Evaluation of the total dietary fiber intake in the population to which Dietary Reference Intakes for Japanese (2020 edition) had been applied was also affected by the difference. These results suggest that it is necessary to check the edition of the Food Composition Table used for the calculation and the method used for the analysis when evaluating the dietary fiber intake status from dietary surveys.
