- Abstract: PURPOSE: To investigate the effects of the intake of xylooligosaccharide-sugar mixture (XOS) on defecation frequency and symptoms in 56 young women (mean age of 22.1 years old) with constipation. METHODS: Two experiments were conducted. In experiment 1, a randomized double-blind study was performed to evaluate the effect of 6 weeks' intake of 10 g sucrose containing 7% xylooligosaccharide or 10 g sucrose on constipation. In experiment 2, 24 g coffee mixture containing 12.8 g plant cream and 11.2 g xylooligosaccharide-sugar mixture was consumed by the subjects. During the study, the clinical efficacy was assessed by using a daily diary. The subjects indicated the number of frequencies they defecated in a day and the clinical symptom scores. RESULTS: In experiment 1, the mean frequency of defecations was 2.07 in the pretreatment week and increased significantly to 4.05, 4.42, 4.84, 4.84, and 4.05 in weeks 2 to 6 of XOS intake, in comparison with the 3-3.67 with sucrose intake (sucrose, SUC). In experiment 2, the mean frequency of defecations significantly increased from 2.47 in the pretreatment week to 4.11-5.67 in weeks 1-6 of XOS intake. The occurrence of very loose or loose stools in the XOS group was significantly increased in weeks 5 and 6, compared with the pretreatment week and SUC group. XOS intake significantly alleviated the abdominal displeasure and feeling of residual stool leftness in weeks 2, 3, 5, and 6, while SUC did so in weeks 4 and 6 (p < 0.05). The coffee mixture containing xylooligosaccharide-sugar mixture reduced the abdominal displeasure and feeling of residual stool leftness from week 3 until the end of the experiment (p < 0.05). CONCLUSION: Our results suggest that xylooligosaccharide-sugar mixture intake was effective, without adverse effects, for the alleviation of constipation in the young women in this study.
