Abstract
The Japanese food standard composition table has been revised after an interval of five years, and the last version includes the contents of iodine, selenium, chromium, molybdenum, and biotin. Although these nutrients were already referred to in the sixth revision of the Japanese Dietary Reference Intake for Nutrient Requirements published in 2000, these nutrients had not been included in previous food composition tables, and therefore the average intakes for Japanese have been unclear. In this study, iodine, selenium, chromium, molybdenum, and biotin intakes were calculated based on three-day dietary records (3DR) in a community-dwelling population aged 40-89 years (1,065 men and 1,050 women). The intakes were estimated by sex and five-year age groups. The median daily intakes of iodine, selenium, chromium, molybdenum, and biotin were 151.0 μg, 50.1 μg, 6.3 μg, 175.8 μg, and 27.3 μg in men, and 117.5 μg, 42.9 μg, 5.3 μg, 132.4 μg, and 23.8 μg in women, respectively.
