Nitrogen retention of young men who consumed between sixteen and eight grams of nitrogen from a combination of rice, wheat, chicken and milk

¹ From Purdue University Agricultural Experiment Station and School of Home Economics, Department of Foods and Nutrition, West Lafayette, Indiana 47907

When young men consumed diets containing 16, 14, 12, 10, and 8 g of nitrogen per day of which rice, wheat, chicken, and milk provided 25, 15, 30, and 30%, respectively, the corresponding mean nitrogen balances were 2.92, 2.01, 1,46, 0.90, and 0.48 g. The regression of nitrogen retention (Y) on intake (X) was linear and highly significant (P < 0.005). The equation was Y = –2.0041 + 0.2895 X, with a correlation coefficient of 0.92. The slope of the regression line did not differ significantly from that obtained earlier when amounts of nitrogen between 8 and 5 g were furnished by a diet in which 50, 25, and 25%, respectively, of the nitrogen were furnished by rice, milk, and wheat. The quantities of essential amino acids in all the diets are presented and discussed in relation to nitrogen retention.
