Thirty-four foods were analyzed in order to determine the content of water-soluble dietary fiber (SDF) and insoluble dietary fiber (IDF). Using the results with the standard table for 227 foods, the intake ratio of IDF/SDF of an average Japanese was calculated for the period 1946-1990. The ratio was 3.22 in 1990 as calculated on the food intakes shown in the national nutrition survey, and the secular change was not detected since 1946 when the ratio was 3.30. The ratio was also shown to be well preserved between types of households including the age of the head. Using dietary records of 60 healthy city workers (average 42.8 years) for 4 weeks, however, the weekly average ratio for an individual was found to vary in the range of 2.25-5.13 although the total average for 60 individuals was 3.33. Thus, the well preserved IDF/SDF intake ratio for an average Japanese showed, on the contrary, a wide variation of food selection between each person.
为了确定水溶性膳食纤维（SDF）和不溶性膳食纤维（IDF）的含量，对34种食物进行了分析。利用这些结果以及227种食物的标准表格，计算了1946年至1990年期间日本人均IDF/SDF的摄入比例。根据全国营养调查中所示的食物摄入量计算，1990年该比例为3.22，自1946年该比例为3.30以来未发现长期变化。该比例在不同类型的家庭（包括户主年龄）之间也保持良好。然而，通过对60名健康城市工作者（平均年龄42.8岁）进行为期4周的饮食记录发现，尽管60人的总平均值为3.33，但个人每周的平均比例在2.25至5.13之间变化。因此，日本人均IDF/SDF摄入比例保持良好，相反，每个人之间的食物选择差异很大。
