Abstract
We investigated the daily intake of dietary fiber (DF) by the enzymatic-gravimetric method. The model menu method and market basket method were employed in order to collect the samples.Model menues were prepared according to the results of the National Nutrition Survey of 1985. Daily intakes were 2088kcal/day energy, 79.0g/day protein, 56.9g/day lipid, 298g/day carbohydrates. Representative Japanese diets for three days were made by four different laboratories. The average value of daily intake of DF was 19.60g (ranging from 15.69 to 31.81g).Market basket composites of foodstuffs were prepared based on the National Nutrition Survey of 1985. The foodstuffs were classified into nine groups. Estimated daily intake of DF was 18.6g. The contribution (%) of each food group to daily intake was: cereals without rice and rice products, potatoes, nuts and seeds 29.4%, vegetables other than green ones, fungi and seaweeds 26.1%, rice and rice products 10.2%, pulses 10.1%, green vegetables 7.0% and fruits 6.1%.
