Nine convalescent malnourished Peruvian infants (ages 7 to 18 months, weight 6 to 11 kg) received pasta diets providing 25, 50 or 75% of energy as wheat. In the 25 and 50% pasta regimens, protein supplied 6.6% of energy, with the composition of the protein being 50% casein-50% wheat protein and 100% wheat protein in the two diets respectively. The 75% pasta diet provided 9.8% energy--all as wheat protein. Balance studies occurred during the last 6 days of seven 9-day dietary periods. Apparent nitrogen retention during consumption of a 50:50 casein-wheat protein mixture equalled that of casein alone. At all three levels of intake, digestion of nitrogen was excellent. In infants, pasta can readily provide a substantial proportion of both protein and energy. It can be used as a weaning food in developing countries; however, without lysine supplementation, it cannot readily satisfy protein needs.
