In this paper, the amounts of supply per capita of vitamins A, B_1 B_2 and C from net foods in Japan were calculated every 5 years between 1965 and 1975, and every year thereafter until 1987 mainly on the basis of the Food Balance Sheets published yearly by the Ministry of Agriculture and Fishery. The values were compared with the intake values reported every year in the National Nutrition Survey by Japanese Ministry of Health and Welfare and the corresponding values in the Recommended Daily Nutrient Allowance (RDA). The results showed : 1) The supply of vitamins A, B_1, and C was smaller than the intake in several years examined. 2) The supply and intake values of all the vitamins satisfied RDA. However, the supply of vitamins A, B_2, and C was not sufficient, when the loss during preservation and cooking is taken into consideration. 3) The additional supply from non-pure foods such as fortified ones seemed considerably high in vitamins A and B_1. The present study suggested that substantial improvement in food supply should be made in order to guarantee sufficient nutrient intake of minor nutrients for the nation.
