The study was carried out on 5 adult males (19-23 yr.) who were given 600 g of well-milled rice or 550 g of brown rice every day for 2 weeks. Those experimental diets contained 1.2 g per kg of protein and 46 kcal per kg per day of energy. The results obtained were as follows:

The wet and dry weight of feces was about 2 times in brown rice period compaired with in well-milled rice period.

The balances of nitrogen, Na, K, P, Ca and Mg showed almost similar values between both period of experimental diets.

As K, P, Ca and Mg which intake increased in order to take brown rice decreased their absorption rate, but on the volume of absorption, K, P, Ca and Mg were similar. Na, K, Cl, P, Ca and Mg concentrations in the plasma were normal in both experimental periods.
