PHOSPHORUS METABOLISM IN INFANTS

Abstract

Although the mineral metabolism of healthy infants has been studied rather intensively by numerous investigators, in few instances has the same child been used as the basis for a comparative study of breast milk and cow's milk. As stated in a previous report, the chief purpose of this investigation was to exclude the possibility of obtaining results that might be interpreted as being due to constitutional differences in the experimental subjects. Therefore this study was conducted on a group of five normal, healthy infants, each of whom during alternate periods (three days each) was given breast milk and cow's milk mixtures. REVIEW OF LITERATURE A survey of the literature shows that many phases of the phosphorus metabolism of infants have been investigated, but there is a striking paucity of information concerning the comparative phosphorus metabolism of healthy infants as studied in the same subject. The results of previous investigators have
