1. Probiotics contribute to the digestion and absorption of nutrients.

Various enzymes released by probiotics in digestive tract are helpful to decompose protein, fat and sugar, and can relieve the symptoms of intestinal malabsorption, which is more conducive to the digestion and absorption of nutrients. For example, adding lactic acid bacteria and bifidobacteria to milk drinks can produce lactose-digestible products, thus alleviating lactose intolerance.

2. Probiotics treat intestinal diseases

In fact, many problems of the human body are caused by intestinal imbalance, that is, intestinal flora imbalance, so as long as the intestinal flora returns to a balanced state, the disease can be treated or alleviated.

The most common use of probiotics in medical treatment is to prevent and treat diarrhea. The clinical application results show that probiotics have a good effect on diarrhea, travel diarrhea, infantile diarrhea and diarrhea caused by antibiotic treatment. In addition, probiotics also show direct effects on intestinal inflammation and functional diseases, such as relieving abdominal pain, bloating and constipation caused by irritable bowel syndrome.

3. Probiotics regulate blood cholesterol, blood lipid and hypertension.

If you eat too much cholesterol in your daily diet, it will have a great impact on blood cholesterol.

Experiments show that probiotics can adsorb cholesterol in food and promote its excretion in vitro. Therefore, taking probiotics or probiotic products can improve the balance of intestinal flora, reduce cholesterol and triglyceride levels, and effectively regulate blood lipids. 4. Probiotics improve human immunity

The immune system is the body's own defense system, which can resist invasion. Under normal circumstances, the flora in the intestine is mutually restricted. When the number of beneficial bacteria is more than that of harmful bacteria, it can prevent the invasion of harmful bacteria and improve human immunity.

Studies have shown that probiotics can activate macrophage activity and increase secretion; It can also produce organic acids, free fatty acids, hydrogen peroxide and bacteriocin to inhibit the growth of other harmful bacteria; It can also colonize mucosa, skin and other surfaces or form a biological barrier between cells to prevent the colonization of pathogenic microorganisms.

5. Probiotics can prevent cancer and inhibit tumor growth.

The anti-cancer efficacy of probiotics has been controversial. As far as the current research results are concerned, its role in preventing cancer is mainly achieved through two ways:

One is that probiotics or their active metabolites can adhere to or degrade carcinogens, thus reducing the body's absorption of carcinogens;

Secondly, probiotics can improve the intestinal environment and inhibit the activities of some enzymes (such as β-glucuronidase, urease, nitroreductase, etc.). ) may be involved in the formation of intestinal carcinogens, thus reducing the incidence of cancer.
