Abstract
By seven successive washing of milled rice by water 90% of thiamine, 60% of pantothenic acid, 50% of riboflavin and 40% of choline were lost.
Rats fed with diet containing washed rice and an appreciable amount of thiamine, riboflavin, pyridoxine and niacin showed a considerable decrease in growth rate and urinary sodium output and elevated blood pressure in comparison with those fed with diet containing unwashed rice. Supplement of pantothenic acid to the washed rice improved the growth, increased the sodium excretion and inhibited the elevation of blood pressure. The reason for frequent occurrences of instances of hypertension among people consuming rice diet was discussed.
