Eight functions of probiotics

There are 100 trillion cells in the human body, of which only 10% of the cells with human DNA are our own, and the remaining 90% are microbial ecosystems composed of bacteria, fungi and other microbial populations. Distributed in our skin surface, gastrointestinal tract, mouth, respiratory tract, urogenital tract and other parts.

They are linked to our health, and a growing body of research shows a strong correlation between the microbiome and metabolic disorders. It can affect your weight, your ability to exercise, the way you digest and metabolize food, it can affect your memory and even your mood.

Among them, there are many kinds and huge numbers of gastrointestinal bacteria, accounting for about 80% of the total number of human microorganisms. There are more than 1,000 kinds of bacteria in the intestines of healthy adults, which number up to 100 trillion, which is 10 times the total number of cells in our body. So, you are not an independent organism, but a community of interdependent and symbiotic bacteria.

The gut microbiota has been shown in studies of humans and animals to play an important role in the pathogenesis of metabolic syndrome. Recent evidence also suggests the role of gut microbiota in insulin resistance, obesity, and related metabolic disorders.

These symbiotic bacteria can be divided into three categories:

Beneficial bacteria

The human body is indispensable, under normal circumstances is the dominant flora, with protection, nutrition, immune regulation and other functions;

Conditioned pathogen

Non-dominant bacteria, such as enterococcus, enterobacter, etc., are harmless when the human flora is balanced, but when the flora is unbalanced, it will attack the human body, resulting in disease;

Pathogenic bacteria

It is harmful to the human body and can lead to diseases, such as Proteus, pseudomonas and Clostridium perfringens.

There is a struggle between the three different symbiotic bacteria, in order to ensure the intestinal and physical health, it is necessary to maintain the balance of intestinal flora, so that beneficial bacteria are in an absolute dominant position, the use of beneficial bacteria to restrict harmful bacteria and conditional bacteria, so that they can not grow wantonly in our body, destroy.

If the human body lacks probiotics, the intestinal flora deviates from the normal physiological combination, resulting in the imbalance of intestinal flora and the proliferation of harmful bacteria, which will cause a series of diseases such as enteritis, diarrhea, constipation, allergy, decreased immunity, and malnutrition. At the same time, a large number of harmful bacteria will also produce indoles, hydrogen sulfide, amines and other harmful substances, these toxins can not only cause intestinal paralysis, are absorbed into the blood, along with the blood flow to other tissues and organs, long-term accumulation may also cause pathological damage to tissues and organs or induce cancer, so that the health of the red light.

Probiotics protect human health

Protect the gut

Probiotics can inhibit the growth of harmful bacteria in the intestine, adhere to the intestinal mucosa to form a protective layer, and prevent harmful bacteria from attacking the intestinal mucosa. It can also directly repair intestinal mucosa with nutrition.

Probiotics can also regulate the activity of intestinal immune factors and enhance intestinal immunity. Therefore, probiotics have a very positive effect in the prevention and treatment of antibiotic-associated diarrhea, irritable bowel syndrome, ulcerative colitis and so on.

抗がん作用

Studies have shown that the increasing incidence of cancer is not only related to the deterioration of the environment, but also related to the imbalance of flora caused by diet, stress and antibiotic abuse. The regulation of intestinal microecological balance by supplementation of probiotics has been proved to have a significant effect on reducing the incidence of cancer.

In March 2017, researchers from the United States, Finland and Sweden jointly published a study showing that the number of caseic acid bacteria in colorectal cancer patients decreased, and after probiotic intervention, the composition of the flora in the tumor site of colon cancer patients changed and began to converge to a healthy state, with an increase in the number of caseinogenic bacteria and a decrease in the number of cancer-related bacteria. It is known that caseic acid is a natural anticancer agent, which may be the main reason for the anticancer of caseinogenes.

In addition to bowel cancer, probiotics have also been confirmed to play a role in liver cancer, bladder cancer, lung cancer, uterine cancer and so on.

Immune Regulation

The dysfunction of the immune system will lead to many health problems, such as allergies, inflammatory reactions, and physical weakness. Studies have found that probiotics can activate macrophages, enhance killer cell activity and increase the level of immunoglobulin A. In particular, the immune regulation of probiotics does not bring about harmful inflammatory responses.

Therefore, for people with low immunity, who are often prone to colds and infections, as well as people with immune dysfunction, eczema, allergic asthma and other symptoms, probiotics can be supplemented to adjust.

Lowering blood lipids

What we commonly call hyperlipidemia is generally classified as hypercholesterolemia, hypertriglyceridemia, or both.

In recent years, more and more studies have found that probiotics can not only inhibit the synthesis of harmful fatty acids and cholesterol, but also bind with cholesterol already formed in the gut and prevent its absorption by the body. At the same time, it can also promote the excretion of lipid substances.

Control blood sugar

Studies have found that intestinal flora imbalance is common in both type I and type II diabetes patients, and supplementation of probiotics can correct the imbalance of intestinal flora and participate in diabetes regulation.

Mental Illness

Human microecological research has found that depression and autism are not diseases caused by mental ill-health, but organic diseases caused by intestinal depressive bacteria.

In 2016, American human microecology experts found that when the intestinal flora is unbalanced, Y-aminobutyric acid in the intestine is eaten up by these depressive bacteria, which will cause depression, autism and so on.

Gut bacteria can produce a variety of neurotransmitters that affect your brain signaling, such as dopamine, serotonin, GABA and other neurotransmitters. The balance of intestinal flora can be adjusted by supplementing with probiotics.

Promote the absorption of nutrients

Middle-aged and elderly people are the high incidence of malabsorption syndrome, the main manifestations of malabsorption syndrome include: steatosis, stool odor containing more oil, abdominal distension, malnutrition is mainly prominent wasting, weight loss, vitamin deficiency.

Probiotics metabolize acid and reduce intestinal pH value, which is conducive to the absorption and utilization of nutrients such as iron, calcium and vitamin D. At the same time, it can also secrete a variety of digestive enzymes to promote the digestion and absorption of nutrients; Some probiotics can also synthesize vitamin B12, vitamin K, etc., which helps to maintain the normal physiological metabolism of the body.

Relieve lactose intolerance

The β-galactosidase produced by probiotics can maintain enzyme activity in the intestine, promote lactose decomposition, supplement the host’s deficiency in digestive enzymes, facilitate the host’s digestion and absorption of lactose, and effectively alleviate the abdominal distension and diarrhea caused by lactose intolerance.
