« This study was performed to estimate the dietary fiber intake calculated using individual food intake data and the dietary fiber tables, and to ascertain the relationship between food intake patterns and dietary fiber intake of the general population. The 805 subjects over 15 years old were obtained from the Tottori Prefecture Nutrition Survey. The results are summarized as follows: 1. The average dietary fiber intake per capita per day was 18.19 g; 18.67 g in men, and 17.81 g in women. Dietary fiber intake per energy was different among sexes and ages: women had more dietary fiber than men and the aged had more than the young. Those who had high fiber intake per energy took green vegetables, fruits, milk, soybean products, seaweed and potatoes more frequently, and did not take oil so frequently. 2. Total dietary fiber intake from 20 food-group sources was analyzed by Multiple Regression Analysis. For both men and women fruits, vegetables and soybean products mostly influenced dietary fiber intake. 3. Based on the intake of the 20 food-groups obtained from 356 men and 449 women, the correlation matrix among these foods was calculated. The correlation matrix was also submitted to a Principal Component Analysis. The result of the Principal Component Analysis told that food intake patterns were different among the levels of dietary fiber intake. Food intake patterns of men and women who had high fiber intake per energy had an eating pattern characterized by relatively more non-processed vegetable food, bread and milk. 4. The level of blood pressure was significantly related to dietary fiber intake per energy in men over 60 years old. In the hypertensive men over 60 years old, 23.3% were in the low fiber intake group, 37.2% in the middle group, and 39.5% in the high group. But in the normal blood pressure men over 60 years old, 50.0% were in the low fiber intake group, 8.3% in the middle group, and 41.7% in the high group. »
