Effect of varying protein and energy intakes on nitrogen balance in Indian preschool children.

Abstract
1. The effect of varying protein intake at two energy levels of 334 and 418 kJ/kg body-weight was studied in four preschool children belonging to the low socio-economic group. 2. Results indicated a curvilinear relationship between N intake and N rentention. From this relationship, the protein requirement of the children at adequate energy intake was calculated. 3. At adequate energy intake (418 kJ/kg body-weight) the protein requirement of the children was 1.33 g/kg. On decreasing the energy intake by 20% to 334 kJ/kg body-weight the protein requirement was found to be increased by 20% to 1.64 g/kg. 4. Based on this study, a safe level of protein intake for Indian preschool children subsisting on a diet based predominantly on vegetable proteins has been suggested.
