National Nutrition Survey has been done every year since 1946. About seven thousand households in 300 randomly selected districts participated this survey. The food intake in each household by weight was recorded on three consecutive days in mid November. In 1989 survey, energy, proteinand fat intake per day per capita were 2, 061 Kcal, 80.2 g, and 42.4, respectively. All nutrient, except calcium exceeded Japanese R.D.A. The proportion of fat in energy was 25.7%. Sodium intake (presented as salt) per day per capita was 12.2 g. It showed regional difference. After the World War II, nutritional condition remarkably improved. Our recent problem is increasingfat intake, positive balance of energy and slow curve of decreasing salt intake. National Nutrition Survey has done its big role of monitoring Japanesenutrition and health condition.
