Abstract
A new macaroni, containing 60% corn (maize), 30% defatted soy flour, and 10% wheat germ (protein = 20.5%), was used in an experiment with Brazilian malnourished children who were treated and fed daily in a nutritional rehabilitation center. The children were served five meals covering their recommended daily allowance for all nutrients for 4 months. One group received 69% of their protein from the macaroni. A control group, in a separate center, received a regular diet containing animal protein, and calculated to provide the same amount of calories, protein, carbohydrate, and fat. Nutritional recuperation was observed in both groups, although anthropometrical and biochemical data indicate a better response in the control group. Acceptability was excellent: the average noodle consumption per child per day was 121 g for 4 months. The authors conclude that the macaroni can be recommended as a supplement. Methodological aspects of the study are discussed, with particular reference to experimental design and interference of infectious processes.
