Improvement of intestinal environment

Rice Kefiran was administered to rats whose intestinal environments had been aggravated by high cholesterol diets, and changes in the intestinal environment were measured using histamine content in the feces and cecal content as an indicator. An increase of histamine in the intestine indicates aggravation of the intestinal environment.
Compared to the control group, the feces and cecal content of the groups fed diets containing 1.5 and 3.0% Rice Kefiran had significantly lower concentrations of histamine. These results suggest that Rice Kefiran improves the intestinal environment.
