The effects of administering a dietary fiber (DF) beverage on defecation and intestinal flora were studied in female college students prone to functional constipation (n=10). The DF beverage (125ml) contained 3g of commercial depolymerized sodium alginate as a non-fermentable dietary fiber and 3g of commercial water-soluble corn bran fiber as a fermentable supplement. The fecal weight was increased (p<0.05) after 2 weeks of administration, suggesting that DF was effective against constipation.The DF beverage resulted in significantly higher (p<0.05) numbers of total microbes, anaerobes, fecal bacteroides and bifidobacterium than those from a placebo during the administration period. The ratio of bifidobacterium to the total number of microbes was also increased by about 40% (p=0.10) at the end of administration. The fecal short chain fatty acid (SCFA) and ammonia contents per weight of wet feces was unchanged by the administration, so the intestinal environment is presumed not to have been adversely affected.These results indicate that the administration of the DF beverage improved both the intestinal environment and intestinal flora.
