Probiotics promote intestinal health by regulating host mucosal and systemic immune function or by regulating the balance of intestinal flora. When the number of probiotics in the intestine is sufficient, the body's digestion, absorption, detoxification, and immune functions are all in a normal state. The intestines can fully absorb various nutrients to ensure the normal operation and repair of various organs, and provide strong immunity to the human body.
Probiotics and harmful bacteria have a placeholder struggle in the intestines. Whoever has more quantity will be in a dominant position. Therefore, taking probiotic supplements can increase the amount, so that it can take nutrients with harmful bacteria and inhibit the growth and reproduction of harmful bacteria.
The main effects of probiotics are as follows:
- 1. Maintain normal intestinal function. Probiotic strains produce digestive enzymes in our gastrointestinal tract, helping us to better digest and absorb nutrients.
- 2. Help lactose intolerance to promote digestion. Probiotics can help lactose intolerants produce galactosidase-active bacteria, thereby solving the adverse reactions such as abdominal pain and flatulence caused by lactose intolerance.
- 3. Enhance human immunity. Active probiotics can colonize the gut and regulate the balance of various flora in the gut. Probiotics can also directly affect the immune system of the intestine and enhance the immune function of the intestine. It also works against stomach acid. The probiotics adhere to the surface of the epithelial cells of the intestine, and a protective membrane is constructed to prevent harmful bacteria from entering the intestines, protecting the gastrointestinal mucosa from damage, and blocking the toxins from entering the other organs of the body for destruction.
- 4. Prevent cancer and inhibit tumor growth. Metabolites such as polysaccharides, bacteriocins, and lactic acid that inhibit tumor growth can be obtained from probiotics, which activate the body's immune system, reduce the pH in the intestine, and stimulate intestinal peristalsis by inhibiting the production of enzymes that convert carcinogens. It eliminates pathogenic toxins and carcinogens in the intestines, thereby reducing the possibility of carcinogenesis.
- 5. Alleviate allergic reactions. In general, the more probiotics in the human gut, the less likely you are to suffer from allergic diseases.
- 6. Lower serum cholesterol. Probiotics have the action of a bile salt hydrolase. It can reduce the absorption of cholesterol by the body's hydrolyzed bile salts and cholesterol.
The human flora should be kept in balance, so the probiotics are not the more the better. Excessive intake and supplementation of probiotics not only can not have a positive effect on the human body, but also may cause the human organs to be overloaded, causing negative effects and disturbing the intestinal environment. In general, probiotics are mainly found in fermented foods such as yogurt, cheese, natto, soybean meal, fermented bean, and kimchi. Fresh fruits and vegetables also contain various prebiotics. It is now also made into a variety of dietary supplements (capsules, tablets, powders). People should focus on eating foods that contain probiotics, rather than relying too much on probiotic supplements.
