Study on Vitamin I Intake of Exclusively Breast-fed Infants

In order to investigate the vitamin I intake of exclusively breast-fed infants, we examined 33 lactating women and their infants at 0.5, 1, 2, 3, 4 and 5 months of lactation. Vitamin E contents of human milk were determined by HPLC analysis. Vitamin E contents of the milk showed 539, 520, 464, 422, 409 and 351$\mu\textrm{g}$/100m1 during the lactation respectively. Vitamin E contents of the human milk were not affected by energy, lipid and protein consumption of lactating women. Vitamin E intake of breast-fed infants averaged 3375 and 269$\mu\textrm{g}$/day in boys and girls during the first 5 months of lactation. Vitamin E intake per body weight of breast-fed infants appeared 725, 752, 600, 461, 420 and 334$\mu\textrm{g}$/kg/day respectively. We conclude that breast-fed infants most likely receives adequate vitamin E from the human milk compared with recommended dietary allowances for Korean infants.
