Six combinations of milled rice, white wheat flour, and nonfat dry milk, all of which supplied 6.0 g nitrogen/day, were administered to young adults. Three diets that furnished either 50 or 75% of the nitrogen from rice were superior to the others; and the diet that contained 75% of nitrogen from rice plus 25% from wheat was as effective as those that supplied 50% of the nitrogen from rice and the remainder from milk alone or milk plus wheat flour. Two combinations were intermediate between these three diets and the least satisfactory one provided 75% of nitrogen from wheat flour and 25% from rice. All of the diets permitted nitrogen equilibrium in some but not all of the subjects, and five out of six induced a mean positive balance.
