The effect of supplementing a poor Indian rice diet with fortified groundnut flour or groundnut protein isolate or skim-milk powder (so as to provide 20 g extra protein daily) on the biological value and digestibility coefficients of the proteins and net protein utilization was studied in 8 girls aged 8-9 years. The true digestibility coefficients of the mixed proteins in the different diets were nearly the same. The biological value of the proteins of the rice diet supplemented with skim-milk powder was higher than of those in the diets supplemented with groundnut flour or groundnut protein isolate. The NPU(op) of the diets supplemented with skim-milk powder was greater than of the diets supplemented with groundnut flour or groundnut protein isolate. The rice diet supplied less, and the protein-supplemented diets more, net available protein than the FAO (1957) "reference" protein requirement.
