Abstract

The invention discloses applications of firmicute probiotics in preventing and/or treating diabetes and relevant diseases, specifically, the firmicute probiotics are used or preparing a composition or a preparation. The composition or the preparation has the following one or more applications: (1) preventing and/or treating diabetes; (b) preventing and/or treating cardiovascular diseases; and/or (c) preventing and/or treating obesity. The firmicute probiotics can obviously inhibit the weight increase, reduce the serum glucose level, reduce the blood lipid level, improve the insulin resistance and/or reduce the glycosylated hemoglobin level, and thus the symptoms of diabetes and relevant diseases can be effectively alleviated.

Description

technical field [0001] The invention belongs to the field of microbiology. Specifically, the invention relates to the application of Firmicutes probiotics in the prevention and / or treatment of diabetes and related diseases, and also relates to a composition containing Firmicutes probiotics and its application. Background technique [0002] There are a large number of symbiotic microorganisms in the human body, most of which live in the human intestinal tract, and the number exceeds 1000 trillion (10 14 Order of magnitude), more than 10 times the total number of human cells. During the long evolutionary process, intestinal microbes have reached a good cooperation with human beings, and play a vital role in the nutrition, metabolism and immunity of the human body. Many researchers regard the human intestinal microbiome as more It is an "organ" of the human body, or the second genome of the human body, and the massive genetic information contained in it is closely related to h...
