Probiotics-how important is it

Good probiotics' functions are mainly reflected in six aspects

Gut probiotics are very important for human health

1. Promote digestion and absorption. Food usually stays in the intestine for more than 12 hours. During this period, probiotics can promote the synthesis of various digestive enzymes to extract various nutrients from food. For example, the short chain fatty acids decomposed by colonic flora through fermentation can promote the absorption of calcium, magnesium and iron in the colon; Another example is that Streptococcus thermophilus can produce lactase and help the human body digest lactose.

2. Strengthen immune cells and protect intestinal mucosa. On the one hand, the self structure of probiotics, such as peptidoglycan and lipoteichoic acid, can enhance the activity and lethality of immune cells; On the other hand, organic acids, hydrogen peroxide and other substances produced by these beneficial bacteria can reduce the permeability of intestinal mucosa and prevent or inhibit the invasion of bacteria into intestinal mucosa.

3. Reduce the risk of cancer. Escherichia coli, Clostridium, Enterococcus and bacteroides in the intestine can promote the combination of nitrite and amine in food to form nitrite amine with strong carcinogenic effect. However, probiotics such as Bifidobacterium and lactobacillus can decompose nitrite amine into nitrite and amine, so as to reduce the risk of colorectal cancer.

4. Reduce cholesterol absorption. Probiotics participate in the liver intestinal metabolic cycle, which can control the flora to interfere with the absorption of cholesterol in food, inhibit the production of liver cholesterol, and promote the excretion of cholesterol in the body.

5. Auxiliary antioxidant oxides in the body, such as oxygen free radicals and hydroxyl free radicals, are prone to redox reactions because of their unstable properties, and excessive quantities may cause oxidative damage. Intestinal probiotics can help clear the oxides synthesized by the body and maintain the dynamic balance of oxidative metabolism.

6. Moisten the intestines and defecate. Normal feces rely on probiotics to maintain 70% ~ 80% water content and discharge smoothly. However, if the number of probiotics is too small and the gastrointestinal motility and digestive capacity are insufficient, it is easy to make the feces stay in the intestine for too long and a large amount of water loss, so that it is difficult to excrete.
