Growth and Retentions of Calcium, Phosphorus and Nitrogen of Infants Fed Evaporated Milk

Abstract

It has been demonstrated, however, that the calcium of certain forms of heat-treated milk is less available to the human infant than is that of quickly boiled fresh milk.2 Because of this it was deemed advisable to study the actual retentions of infants fed evaporated milk.For this purpose nine healthy male infants were studied for periods lasting from eighteen to forty-eight weeks. The evaporated milk used for the feedings was purchased in the open market, diluted with an equal quantity of 12 per cent corn syrup solution and acidified with lactic acid. This mixture was intended to be approximately equivalent to undiluted acidified fresh milk with the addition of 6 per cent corn syrup, which had been employed for similar observations on another group of infants during a preceding period.3 In order to compare the utilization of evaporated milk with that of fresh milk, an attempt was made to keep the quantities of food and the additions to the diet the same, according to age, in the two groups. Certain changes were found neces¬ sary because it was observed that in some of the very young infants the
