The effect of the degree of polishing of rice on nitrogen and mineral metabolism in human subjects



The effect of the degree of polishing of rice on nitrogen and mineral metabolism in human subjects



Cereal Chem 37(1): 71-78



Adult human subjects showed slightly negative C balances when brown rice or rice polished to remove 2.9% of the brown rice formed the cereal portion in their vegetarian diet. Rice which was polished to remove 4.1% or 6.3% of the brown rice produced slight positive balances. The deleterious effect of the exclusive consumption of brown rice or rice polished to remove less than 3% of the bran in rice diets containing marginal or submarginal amounts of C is thus indicated. N and P balances were about the same with the rice samples polished to different degrees. In spite of its higher protein and P content, the brown rice did not induce higher N or P retentions.
