In this paper, the amounts of supply per capita of energy, three major nutrients, calcium and iron 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. Although the supply values of energy and three major nutrients have been described every year in the Food Balance Sheets, we recalculated them since slightly different procedure was employed in this paper. These supply 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 energy and the three major nutrients was in excess compared with the intake every year, which supported the general recognition that foods are saturated both in quantity and quality. 2) However, the supply of calcium and iron was not always sufficient, being smaller than the intake in many years examined. 3) Particularly, the supply of calcium was constantly smaller than RDA. 4) The additional supply from non-pure foods such as fortified ones did not justify the calcium supply.
