Nitrogen-balance studies on rice diets.

During a series of experiments designed to study mineral metabolism on rice diets (Cullumbine, Basnayake, LeMottee & Wickramanayake, 1950), it was also found possible to estimate the nitrogen content of the food and excreta for the group of twelve subjects and so to determine whether there were any differences in the nitrogen metabolism of subjects when eating diets first high in unpolished rice and then high in polished rice.
