We evaluated the effects of a dessert beverage supplemented with indigestible dextrin (4.2 g of dietary fiber) on frequency and fecal characteristics in 38 healthy female students (age 19.8 ± 0.9 years). The subjects were divided into two groups for a crossover study. The study duration of 7 weeks was divided into 5 periods: non-intake period (I: one week, control period); intake period (II: two weeks, test period); non-intake period (III: one week, free period); intake period (IV: two weeks, test period); and non-intake period (V: one week, free period). A beverage containing no indigestible dextrin was used as a placebo. For the entire seven weeks, the subjects filled out daily questionnaires concerning their defecation and fecal conditions and weekly questionnaires concerning their health conditions. Subjects with slight constipation significantly increased their frequency of defecation, the number of days with defecation, and the amount of defecation during the test period when they received the beverage containing indigestible dextrin, as compared to the control period (n=12). Moreover, these subjects also significantly increased their number of days with defecation compared to those when consuming the placebo beverage. The health conditions questionnaire also showed an improvement in constipation when the subjects consumed the beverage containing indigestible dextrin.
