Abstract:
Based on the result of the Aomori Nutrition Survey, we have calculated daily dietary fiber (DF) intake using modified Southgate and Prosky methods. Result obtained were as follows: DF intake in Aomori was 23.7 +/- 8.4g by the modified Southgate method, and 22.2 +/- 8.5g by the modified Prosky method. As for supply sources of DF, 32.3% was from grains; 22.7%, vegetables; 15.6%, beans; and 7.8%, fruits calculated by the modified Southgate method, and 31.3%, vegetables; 19.0%, grains; 18.0%, beans; and 11.6%, fruits by the modified Prosky method. As to types of DF, intake of hemicellulose was 11.5 +/- 4.2g, cellulose 7.8 +/- 3.0g and lignin 4.4 +/- 2.3g. In the group with DF intake below 10.0g, DF came mainly from grains and fruits, while the group with DF intake above 30.0g took DF from various foods.
