The essential trace elements such as Fe, Zn, and Mn play an important role in human growth and development. The purpose of this study was to estimate the daily intakes of Fe, Zn, and Mn in Korean elementary school students. A total 1,320 elementary school students aged 6 to 11 years participated in this study. A 24‐hr recall method for 3 days was conducted and daily intakes of Fe, Zn, and Mn were calculated. The mean daily intakes of energy, Fe, Zn, and Mn were 1852.4 kcal, 13.4 mg, 9.1 mg, and 4.5 mg for boys aged 6 to 8 years and 1764.3 kcal, 13.0 mg, 8.6 mg, and 4.2 mg for girls aged 6 to 8 years and 1830.1 kcal, 13.0 mg, 9.2 mg, and 4.4 mg boys aged 9 to 11 years and 1783.1 kcal, 12.5 mg, 9.0 mg, and 4.2 mg girls aged 9 to 11 years, respectively. The major food groups consumed Fe and Mn were cereals, vegetables, and pulses and Zn were cereals, meats, and vegetables. The median intakes of Fe, Zn, and Mn in total subjects were 12.7 mg, 8.8 mg, and 4.2 mg and were more than their recommended intakes (RIs of Fe and Zn) and adequate intake (AI of Mn). Daily intakes of Fe, Zn, and Mn of elementary school students participated in this study were sufficient compared with the dietary reference intakes. However, in order to assess accurately trace elements in elementary school students, systematic balance study examining their intakes and excretions is needed in future.
