We investigated the effects of germinated barley foodstuff (GBF) on the fecal
excretion and jejunum mucosal protein content in male Sprague-Dawley rats fed on
various diets with the same protein and dietary fiber levels. Under these
experimental conditions, GBF was confirmed to induce greater fecal output
compared with commercial water-soluble or -insoluble dietary fibers. While the
dietary fiber extracted from GBF increased the fecal output and mucosal protein
content, the protein fraction of GBF degraded to the peptide form did not
increase the fecal output or mucosal protein content. Increased mucosal protein
and fecal output were thus found to require the presence of the dietary fiber
fraction or possibly the protein fraction bound tightly to the dietary fiber of
GBF. GBF feeding increased the volatile fatty acids concentration in the cecum,
indicating that GBF may be efficiently fermented in the intestinal tract.
