Abstract
Daily intake of vitamin E by Japanese woman was estimated by two kinds of surveys. First survey (Survey I) was based on the meal survey in 3 different areas, Sapporo, Yokohama and Osaka Cities, which are considered to be different in local food consumption. In the second survey (Survey II), a model menu method was used to reflect local food characteristics of Tohoku, Kantou I, Kinki I and South-Kyushu areas based on National Nutritional Survey. Daily intakes of vitamin E as α-tocopherol equivalent was calculated by the Japanese Food Composition Tables (1989). Obtained results are as follows; In Survey I, mean and median values of daily vitamin E intake in 3 areas were 10.3±4.0 mg and 9.7 mg, respectively. These values were over Recomended Dietary Allowances in Japan (RDA)( for female, 7 mg. But daily intakes of vitamin E were 3.8 to 23.8 mg, showing wide personal differences, intake levels of and about 20% of female were under 7 mg. approximate contributions to daily vitamin E from breakfast, lunch and supper were 25, 26 and 43%, respectively. In Survey II, although model menus were provided to reflect local food custom of four areas, mean levels of vitamin E intake were not significantly different. Both surveys, showed that non-α-Toc contributed by about 8% to daily vitamin E intake.
