Sometimes, in order to make an article brief, authors quote others, but the interpretations of the new authors may not reflect the context of the original observers. This has occurred in the quotation of several of our papers in a recent article by Pincus et al.
First we are quoted as agreeing "that small infants where fed isocaloric diets gain weight more rapidly on a diet having a higher protein content" (author references 12 and 16). In reference 12,2 we state that infants fed 3.0 to 8.0 gm of protein per kilogram gained equally well. Only when the protein intake was below 2.0 gm/kg did the weight curve not rise as well. Indeed, in this paper, we noted a few babies taking more than 8 gm/kg protein who gained very poorly.
