What is the function of Bifidobacterium?

Bifidobacterium is a kind of anaerobic Gram-positive bacilli isolated from the feces of breast milk nourished children by French scholar Tissier in 1899. The number of bacteria distributed in the stomach and intestines decreases with the increase of age. Bifidobacterium accounts for 60% of the total intestinal bacteria in infants and only 7.9% in people over 60 years old. Let's take a look at the role of bifidobacteria.

Nutritional effect of Bifidobacterium

1. Absorption promotion: Bifidobacterium can produce lactic acid and acetic acid after intestinal fermentation, which can improve the utilization rate of calcium, phosphorus and iron and promote the absorption of iron and vitamin D. Bifidobacteria ferment lactose to galactose, which is a component of brain glycosides in the brain nervous system, which is closely related to the rapid growth of the brain after birth. Bifidobacterium can produce essential nutrients such as vitamin B1, B2, B6, B12 and alanine, valine, aspartic acid and threonine, which can not be ignored.

2. Anti-aging effect: the microecological investigation in Europe, America and Japan shows that the number of bifidobacteria in the feces of the long-lived elderly is similar to that of the middle-aged and young people, and the same results have been obtained from the investigation of the long-lived elderly in Bama area of Guangxi by Chinese scientists. The reason for the anti-aging of Bifidobacterium is that Bifidobacterium can inhibit the growth of spoilage bacteria and reduce the production of harmful substances such as ammonia, hydrogen sulfide, indole and faecal odor in its metabolites.

3, disease prevention effect: bifidobacterium is different from general drugs, general drugs are one-way treatment, such as lowering blood pressure, lowering blood lipids, treating diarrhea, treating constipation and so on. The role of bifidobacteria is two-way adjustment, can not only lower the high, but also raise the low, the use of bifidobacterium preparation may simultaneously treat diarrhea and constipation, so that the human body back to normal, this is the role of adjustment.

Pharmacological effects of Bifidobacterium

1. Treatment of chronic diarrhea: Bifidobacterium can treat chronic diarrhea. The clinical observation of patients with chronic diarrhea with Bifidobacterium showed that after two weeks of treatment, the number and shape of stool were abnormal, the clinical symptoms disappeared, the total effective rate was 90.3%, and the recurrence rate was low. Many domestic hospitals have taken Bifidobacterium preparation as the first choice for the treatment of chronic diarrhea.

2. Prevention and treatment of constipation: Bifidobacterium is mainly used for functional constipation, which is closely related to intestinal bacterial imbalance and mostly cause and effect each other. It is caused by the increase of spoilage bacteria such as intestinal foreign bacteria (or passers-by bacteria), which produce corresponding toxic metabolites such as amines, phenols, indole and so on. By adjusting the normal intestinal flora and restoring the balance of normal intestinal flora, the number of spoilage bacteria is greatly reduced, and the absorption of toxic metabolites is reduced, so that the symptoms of constipation can be alleviated.

3. Prevention and treatment of tumorigenesis: aflatoxin is a fungal toxoid that often contaminates food, which can induce liver cancer. The experimental results confirmed the ability of Bifidobacterium to bind aflatoxin in vivo. In addition, Bifidobacterium can combine with inducers such as nitrosamine or nitrosoguanidine to mask the active genes of mutagens, or degrade the active genes of mutagens to promote their activity.

4. Protect the human liver: harmful bacteria in the human intestinal tract produce and release toxins into the blood, causing serious damage to the liver. Bifidobacterium preparation can inhibit the number of harmful bacteria producing toxin, so it has a good therapeutic effect on liver patients. Bifidobacterium can also be used to treat liver coma, inhibit hepatitis B virus and promote the conversion of big and small three positive to negative.

5. Prevention and treatment of cardiovascular disease: the content of cholesterol in human blood will lead to arteriosclerosis and hypertension. Beneficial bacteria such as Bifidobacterium can affect cholesterol metabolism, convert it into steroids that are not absorbed by the human body, and reduce the concentration of cholesterol in the blood. Therefore, it has a certain role in the prevention and treatment of hypertension and arteriosclerosis.

6. improve lactose digestion: milk is a good food for the elderly and babies, but a considerable number of Chinese people lack lactase and cannot break down lactose in milk. these people often have gastrointestinal disorders after drinking milk. cause gastrointestinal cramps, flatulence or diarrhea, forcing this population not to drink milk, thus giving up other important ingredients in milk Bifidobacterium can produce lactase in the process of dairy fermentation to help patients digest lactose.

What is the function of Bifidobacterium?

1. Inhibition of bacterial infection: a large number of bifidobacteria inhabit the intestines of healthy people. The most typical example is breast-fed babies, whose intestinal flora is 99% bifidobacteria. Because Bifidobacterium can produce acetic acid and lactic acid, the PH value in the intestine tends to be strongly acidic, so it can inhibit the reproduction of pathogenic bacteria and prevent human body from infection. This is the reason why babies who drink mother's milk have less diarrhea or enteritis and lower mortality than those who drink milk.

2. Inhibition of intestinal corruption: when proteins are decomposed by bad bacteria in the intestine, they will form corrupt substances such as amine, ammonia, indole, hydrogen sulfide and so on. After these substances are absorbed by the human body, they become the causes of constipation, diarrhea, cancer, hypertension and other diseases, and accelerate the aging of the body. As mentioned above, the reason why feces stink is also due to these rotten substances. If bifidobacteria and bad bacteria win the battle, intestinal decay can be suppressed.

3, can make vitamins: inhibiting intestinal decay is not the main function of Bifidobacterium, Bifidobacterium can indeed produce vitamins B1, B6, B12, K12, niacin and iodine. Some of them will be absorbed by the body, which is of great help to the human body.
