According to table 7, the intestinal flora of the model group mice was significantly changed and gram-negative bacilli were significantly increased (p <0.05) compared to the normal control group, indicating that the intestinal dysbacteriosis model of the mice was successfully established. And the number of the intestinal flora of the mice in the composition intervention group is obviously recovered, the number of gram-negative bacilli is obviously reduced, and the difference with the model group has statistical significance (# p < 0.05).
Similar results were obtained with the above test conducted in example 5, which shows that it is also effective in reducing intestinal harmful bacteria (LPS producing bacteria) without the addition of taste-harmonizing adjuvants, to aid in anti-intestinal aging, while preventing intestinal dysbacteriosis.
In conclusion, the composition for resisting intestinal aging and the application thereof can effectively reduce intestinal harmful bacteria (LPS-producing bacteria) so as to assist in resisting intestinal aging and prevent intestinal dysbacteriosis.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
