Longitudinal calcium (Ca), magnesium (Mg), and phosphorus (P) concentrations were measured in 18 nursing mothers' milk and in the sera of the mothers and their infants over a 6-month period. It was found that increases occurred in serum Ca and Mg concentrations of both infants and mothers over the study period, in association with a decreasing P content of the breast milk. It is suggested that the rise in serum Ca and Mg in the infants may be partly accounted for by a decrease in dietary phosphorus intake. (wz)
