Abstract

The protein requirements for various age groups have been calculated by factorial method. For calculating the nitrogen required for maintenance, the factors suggested by the U.E.Expert Panel (2.65 mg.N/basal K Cal) and the Food and Nutrition Board, N.R.C., U.S.A. (3:2 mg.N/basal K Cal) have been used. The nitrogen requirements fbr growth were calculated using the data given in the report of the FAO/WHO Expert Group. The mean of values for total N requirements obtained by the two methods multiplied by the conventional factor 6.25 has been taken to represent the reference protein requirements. To this value, 20% excess has been added to allow for individual variations, as suggested by FAO/WHO Expert Group. The revised reference protein requirements expressed as g/kg body weight are as fellows Infants, 2.37 to 1.48 g; children, 1-3 years, 1.48 to 1.19 g; children 4-6 years, 1.06 g; children 7-9 years, 0.96 g; children 10-12 years, 0.84 g; adolescent boys, 0.93-0.76 g; adolescent girls, 0.83 to 0.67 g; adults-men, 0.55 g; women, 0.51 g; pregnant women, 0.71 g :nd lactating women, 0.91 g. The revised reference protein allowances for children 1-3 years are higher and for adult men and women lower than the corresponding allowances suggested by the FAO/WHO Expert Group. The revised protein allowances are as follows in terms of NDP Cal %i Infants, 8.0 to 6.0; children, 1-3 years, 6.0 to 5.3; 4-6 years, 5.3; 7-9 years, 4.9 and 10-12 years, 4.8; adolescent boys 6.6 to 6.2; adolescent girls, 7.1 to 6.2; adult men, 4.5; adult women, 4.8; pregnant and lactating women 5.5. The data indicate that the protein requirements can be expressed both as grams per kilograc body weight or as NDP Cal %.
