Critical evaluation of new or enriched protein sources for the prevention of malnutrition, progress report on whey - soy mix

WHEY-SOY PROVED TO BE SIGNIFICANTLY INFERIOR TO CASEIN IN NITROGEN RETENTION, PARTLY ON THE BASIS OF POOR DIGESTIBILITY AND PARTLY BECAUSE OF A PRESUMED BIOLOGIC VALUE. STOOL WEIGHTS AND FECAL FATS DID NOT DIFFER SIGNIFICANTLY IN THE TWO DIETS. CHILDREN CONSUMING WHEY-SOY AS THE ONLY SOURCE OF PROTEIN SHOWED GOOD INCREASES IN WEIGHT AGE WITH LESSER INCREASES IN LENGTH, A NORMAL FINDING. SERUM ALBUMIN CONCENTRATIONS GENERALLY WERE WELL-MAINTAINED. NO INTOLERANCE TO WHEY-SOY WAS ENCOUNTERED. POSSIBLE LIMITATIONS IN THE USE OF WHEY-SOY IN FIELD SITUATIONS MUST BE TAKEN INTO ACCOUNT, BUT IT SHOULD PROVE TO BE OF GREAT VALUE EVEN IN THE DIETS OF WEANED INFANTS.
