The purpose of this study is to investigate zinc and copper intakes of exclusively breast-fed infants. We measured consumed volume and the minerals concentrations of human milk from thirty three lactating women and their infants during the first 5 months of lactation , Zinc concentrations of human milk showed 0.394, 0.290, 0.191, 0.147 and 0.139mg/100g at 0.5, 1, 2, 3, 4 and 5 months of lactation respectively. Copper concentrations in the milk showed 61.04, 45.97, 37.15, 3.94, 26.22 and 26.21$mu extrm{g}$/100g respectively. Consumed volume of the milk of infants were 515, 650, 718, 731, 746 and 769g/day. There is significant difference between boys and girls in consumed volume of the milk at 2, 3 and 4 months of lactation. Zinc intakes of breast-fed infants declined(p<0.05) from 2.13mg/day at 0.5 months to 1.21mg/day at 3 months with no change thereafter significantly. Copper intakes of the infants declined(p<0.05) from 323.2$mu extrm{g}$/day at 0.5 months to 238.9$mu extrm{g}$/day at 3 months with no change thereafter. Form this survey, the reevaluation of zinc and copper intakes and recommended dietary allowance of those minerals during infancy are merited. (Korean J Nutrition 33(8) : 857-863, 2000)
