Lactic acid bacteria play a very important role in human body, especially in maintaining intestinal health. They play a vital role. In addition to the intestine, there are many lactic acid bacteria distributed in people's mouth. The influence of lactic acid bacteria on human body mainly includes the following aspects.
First, it can maintain the balance of intestinal flora.
Lactic acid bacteria reproduce and metabolize to produce lactic acid after entering the intestine. These flora can inhibit the reproduction of harmful bacteria, prevent harmful flora from entering the stomach, and maintain the balance of flora in the intestine.
If there are not enough lactic acid bacteria in the intestine, the pathogenic bacteria in the intestine will multiply in large numbers, which will cause intestinal infection and produce a series of gastrointestinal diseases.
Second, bacteriocin and other bacteriostatic substances are produced.
Appropriate supplementation of lactic acid bacteria in human body can inhibit the reproduction of harmful bacteria, just as lactic acid bacteria in female reproductive tract can occupy favorable territory through competition, thus inhibiting the production of Candida albicans.
Third, it can improve immunity.
Lactic acid bacteria can stimulate the production of immunoglobulin and enhance the body's resistance. According to relevant research reports, many flora can stimulate human immunity and play a vital role in infants and the elderly.
When the lactic acid bacteria in the body decrease, the immunity of the human body will also decrease, and it is easy to get allergic to colds.
Fourth, it can help to synthesize vitamins.
Many people don't know that lactic acid bacteria can also synthesize vitamin B. When the number of lactic acid bacteria in the human body decreases, the synthesis speed of vitamin B will be greatly slowed down, resulting in slow metabolism and even disorder of hormone secretion.
Fifth, it can regulate blood lipids and prevent rectal cancer.
Now rectal cancer has become a high incidence cancer. Lactic acid bacteria can reduce the absorption of cholesterol in intestine, regulate blood lipid and prevent rectal cancer.
