Japanese salt intake is calculated through the Food Compo sition Table in the National Nutrition Survey, whereas English salt intake is through urinary sodium excretion in 24 h. This study is a comparison of salt intake between Japan and England. As different measuring methods were used in both National Nutrition Surveys, we recalculated using the same measuring method. Seven Japanese young women's sodium intakes were calculated through the Food Composition Table, and the amounts of their urinary-excreted sodium were measured. These quantities were compared, and a coefficient (87.7%) was obtained. The Japanese young women's salt intake was 9.74g/day from the Japanese National Nutrition Survey, and the coefficient was multiplied by 8.51g/day. While comparing these experimental results with English data in 1992, the English salt intake converted from sodium intake of 3, 040mg/day was 7.72g, 0.79g/day lower than the Japanese salt intake.
