Intestinal tract is one of the important organs of human body. Its main function is to help human body digest food and absorb nutrition. At the same time, it also has an important function to protect human health and provide us with an important immune barrier. The real exercise of these specific functions is not only the intestinal tract itself, but also depends on the large number of microorganisms living in the intestinal tract. Together with the intestinal tract, these microorganisms create a set of intestinal micro ecosystem to complete together, such as immunity and nutrition Supply and other functions
There are three kinds of microbial groups in our intestines: probiotics, neutral bacteria and pathogenic bacteria, and enough probiotics are the colonies that really help us maintain health. There are many members in this colony, including bifidobacteria, Lactobacillus, Enterococcus and yeast.
The main functions of probiotics in our body include the following:
1. Maintain the balance of intestinal flora
The regulatory mechanism of probiotics on intestinal flora can be summarized as follows:
Biological antagonism. Probiotics are generally the predominant flora in the intestine. After entering the intestinal tract, it will propagate rapidly and compete with other pests for nutrition and the mucosal space adhered to. At the same time, it will also actively secrete antibacterial substances, such as antibiotics, hydrogen peroxide, etc., which will hinder the growth of other pests.
Change intestinal pH. During the growth process of probiotics, most kinds of probiotics will ferment to produce lactic acid, which can effectively reduce the pH value of intestinal tract, thus inhibiting some harmful microorganisms unable to withstand the acid environment.
Repair intestinal mucosa. Probiotics have the functions of protecting intestinal mucosa, alleviating inflammation of intestinal mucosa and assisting in repairing intestinal mucosa.
2. Improve human immunity
The regulation mechanism of probiotics to the immune system is complex, but its core is to stimulate the host's immune response, enhance humoral and cellular immunity, and thus increase the body's immunity.
Probiotics are widely used in the prevention and treatment of intestinal diseases, including the following main application areas:
1 for the treatment of diarrhea:
Diarrhea can be divided into intestinal pathogenic microorganism or parasite infection, functional or organic diseases of digestive system, metabolic diseases, autoimmune diseases, radiation enteritis, and intestinal flora disorder caused by antibiotics. However, no matter what causes diarrhea, it will inevitably cause serious disorder of intestinal flora. Therefore, probiotics have become an important auxiliary treatment for diarrhea, and play an important role in restoring the balance of intestinal flora.
2. Improve intestinal microenvironment, regulate constipation:
Constipation does great harm to human body, which is a very painful thing. At the same time, due to the accumulation of feces in the intestinal tract for a long time, constipation patients are easy to induce the reproduction of intestinal spoilage bacteria, resulting in the deposition of toxins. Now there are many ways to treat constipation, including taking cathartic, enema, etc. according to the latest research, the intestinal flora of patients with constipation is also very different from that of healthy people. This kind of flora difference is also likely to be a cause of human constipation. In any case, the patients with constipation should pay attention to the regulation and recovery of intestinal flora in addition to other means, and probiotics can help us effectively improve the intestinal microenvironment, maintain the balance of intestinal flora and promote intestinal peristalsis.
Adjuvant treatment of inflammatory bowel disease
Inflammatory bowel disease is a kind of chronic intestinal inflammatory diseases, including ulcerative colitis and Crohn's disease. The main symptoms were diarrhea, abdominal pain and intestinal discomfort. At present, the pathogenesis of the disease is generally considered to be related to genetic factors, immune factors and environmental factors. Therefore, the treatment of inflammatory bowel disease can start from regulating intestinal flora and eliminating intestinal inflammation. At present, probiotics are usually added on the basis of traditional treatment, and probiotics are used as auxiliary treatment.
With the continuous research and development of probiotics from all walks of life, the scope of application of probiotics is also expanding, including the intestinal tumors that we think are more difficult at present, which have a corresponding relationship with the flora in our intestines. It is also possible for probiotics to be used in the prevention and treatment of such diseases in the future. Let's look forward to the application of probiotics Open a new door to our health.
