Probiotics are a kind of active microorganisms parasitized in human intestinal tract, which have certain effect of improving human immunity.
Intestinal probiotics can compete with harmful bacteria for oxygen and nutrients, inhibit the colonization of harmful bacteria and maintain the balance of intestinal flora. Probiotics play a role in resisting and preventing diseases by stimulating the proliferation of immune substances in the intestinal mucosal epithelium lymph nodes and other parts of the intestinal mucosa, activating immune cells.
In addition, the balance of intestinal flora can improve indigestion, increase intestinal digestion and absorption, ensure the normal absorption of vitamins, trace elements and other nutrients, and maintain the overall immune level of the body.
It is worth noting that probiotics can only play an auxiliary role in improving immunity, but also need to be combined with a regular diet, work and rest, moderate exercise and other ways to scientifically and rationally improve the quality of the body. If the body has obvious low immunity, it is necessary to consult a doctor to rule out pathological factors, such as various primary and secondary immunodeficiency diseases.
