The Influence of Caloric Intake on the Growth Utilization of Dietary Protein

Abstract

Caloric intake and protein utilization have been compared in growing rats and mice that were eating ad libitum. With each protein source it was found that the level of intake exhibiting maximal protein utilization coincided with a maximal caloric intake per unit of body surface area. At a given level of protein intake, changes in caloric consumption often resulted in changes in the apparent utilization of protein. It is important in determinations of protein quality to maintain the non-protein caloric intake at a level at which optimal values will be obtained.
