A study of 3-day food diaries and of vitamin D analysis of breast milk and infant serum samples from 25 mother-infant pairs (10 black, 15 white) assessed the effect of race and food habits on the nutritional value of the mothers' breast milk to their infants. Vitamin D metabolites, D3, D2, and 25-hydroxyvitamin-D3 (but not 25-hydroxyvitamin D2) were lower in the milk of black mothers than in that of white mothers. Total milk vitamin D (but not 25-hydroxyvitamin D) correlated with dietary intakes of vitamin D, and milk vitamin D2 correlated with dietary vitamin D intake even after controlling for race differences. However, neither milk vitamin D nor 25-hydroxyvitamin D levels correlated with infant serum 25-hydroxyvitamin D, suggesting that vitamin D intake from mothers' milk by these infants may have an insignificant contribution to the infants' vitamin D status relative to the contribution from sunlight exposure.(wz)
