We evaluated the effects of ingestion of a soluble indigestible dextrin on the defecation in 22 late elderly residents in a nursing home. The experimental duration was 8 weeks, which was consisting of before-administration period (2 weeks), administration period (4 weeks) and after-administration period (2 weeks). Subjects took 100 ml green tea containing 10 g of indigestible dextrin at every afternoon tea time for 4 weeks in the administration period. In the results, the subjects' estimated fecal characteristics significantly improved in the administration and after-administration periods compared to those in the before-administration period. While, there was no significant difference in the defecation frequency or in the frequency of laxative administration in the experimental periods.
