EVIDENCE that the growth lag of children with chronic nutritive failure may be reduced by the daily addition of milk supplements to inadequate diets has been presented in previous reports from this clinic.1 In these studies, 41 children with retarded growth associated with chronic undernutrition were given a dietary supplement of reconstituted milk solids equivalent in protein value to that contained in 1 qt. (0.9 liter) of cow's milk. The supplements were given 6 days per week for a period of 20 months. Despite the added milk, the diets of this group remained deficient in calories and in several of the essential nutrients for which standards have been accepted.1b Nevertheless, these children gained an average of 1.23 cm. and 1.35 kg. over and above the gains made by ethnically and nutritionally comparable children who did not receive added milk and who served as the reference group.1b While
