“…Provided that SCFAs are generated from dietary fibers and indigestible carbohydrate by an extensive set of enzymes of gut bacteria, it can be potentially explained that increment of fecal SCFAs by YBL treatment was a consequence of that dietary fibers in YBL were utilized fermentatively with the production of SCFAs in the large intestine. Previous literature by Saito et al (2005) showed that insoluble dietary fiber from young barley had little impact on cecal SCFA levels in a rat model. Given that the soluble type of dietary fibers generally tends to be highly fermentable, it is reasonable to say that the soluble type of dietary fibers from YBL might contribute to the increments of fecal SCFAs.…”

Short-chain fatty acids (SCFAs) bacterially produced in the intestine provide a variety of physiological effects for the host. The present before-after clinical trial was conducted to investigate the effects of young barley leaf extract (YBL) on fecal SCFA levels. For 4 weeks, female health subjects were asked to ingest two sticks (8 g) of test sample daily. Feces were collected before and after the period of treatment with YBL. Results demonstrated that YBL significantly elevated the fecal concentrations of acetate from 23.6±7.5 to 36.4±8.1 μmol/g (p<0.001) and propionate from 10.0±5.2 to 13.6±7.1 μmol/g (p<0.05) but, did not give an advantage in fecal bacterial composition. Interestingly, YBL also raised the fecal moisture by 3.9% point from the baseline (p<0.05).
