By seven successive washings of polished rice by water 90% of thiamine, 60% of pantothenic acid, 50% of riboflavin and 40% of choline were lost.<BR>Rats fed diet containing washed rice and adequate amounts of thiamine, riboflavin, vitamin B<SUB>6</SUB> and nicotinic acid showed a considerable depression in growth. Urine volume and urinary sodium output decreased and blood pressure was elevated in comparison with those fed diet containing unwashed milled rice. Supplement of pantothenic acid to the washed milled rice diet counteracted almost completely the adverse effect of washed rice diet on the sodium excretion and blood pressure.<BR>The reason of frequent occurrence of incidence of hypertension among people consuming washed rice diet was discussed.
