Nutritional supplementation--whom does it benefit most?

Two hundred eleven preschool children who had received a food supplement and a group of 82 children who had not received any supplement were classified into various nutritional groups. Data on their increments in height and weight were analyzed to determine whether different groups behaved differently. The results indicated that those who were most severely malnourished benefited the most from the nutritional supplementation program and also that following on such programs nutritional dwarfs would have a chance to move toward normalcy.
