Abstract

Maize is consumed widely as a staple food by the low-income groups in Africa, Latin America and other parts of the world (FAO, 1953). In India maize is consumed to a limited extent along with millets in some States (Patwardhan, 1952). The main nutritional defects of maize as compared with other cereals are ( I ) its low content of nicotinic acid and (2) the deficiencies of its proteins in tryptophan and lysine, and the imbalance between isoleucine and leucine (FAO, 1953). The incidence of pellagra and kwashiorkor is high among maize-eating populations (FAO, 1953; Autret & BChar, 1954). Scrimshaw, Bressani, BChar & Viteri (1958) reported that the retention of nitrogen in children aged 3-4 years was low on a maize diet providing about 3 g protein/kg body-weight. Similar observations on young children aged 1-3 years have recently been reported by Hansen, Schendel, Wilkins & Brock (1960).T ruswell & Brock (1959) found that four out of six adults fed on a maize diet providing I g protein/kg body-weight maintained a slight positive N balance and two were in negative balance. No information is available on the metabolism of nitrogen, calcium and phosphorus in older children on poor maize diets. In view of the shortage of rice in India, the use of maize and other grains as a partial substitute for rice needs to be studied. This paper describes the results of investigations on the effect of replacing rice in a poor Indian diet partly or completely by maize on the metabolism of N, Ca and P, and on the digestibility coefficient, biological value of the proteins and net protein utilization in children.
