What are lactic acid bacteria? Is it harmful to the body?

1. Lactic acid bacteria can be roughly divided into two categories. One is animal-derived lactic acid bacteria, because the animal source is taken from animals, because the bacteria are often in a relatively unstable state, their biological efficacy is also relatively unstable, and when eaten in large quantities, it is easy to cause human animal protein allergy, that is, rejection.

2. One is plant-derived lactic acid bacteria. The plant-derived lactic acid bacteria, because the ruler is quietly taken from plants, is easy to be recognized by the human body, no matter how large the amount of ingestion, the human body will not produce allogeneic protein rejection reaction, and the plant-derived lactic acid bacteria are more energetic than those of animal origin, and can reach the small intestine of the human body for colonization in 8 times more than the animal source, so as to exert its strong and stable biological effect.

Lactic acid bacteria have a variety of health benefits as beneficial bacteria that settle in the intestines.

Lactic acid bacteria refer to a general term for a class of non-spore, Gram stain-positive bacteria whose main product of fermented sugars is lactic acid, and bacteria that can produce lactic acid bacteria from the fermentation process of glucose or lactose are collectively called lactic acid bacteria. Guideline lactic acid bacteria are a type of probiotic that is found in the human body. Lactic acid bacteria can ferment carbohydrates into lactic acid, probiotics can help digestion, and help the health of the human intestines, so it is often regarded as a health food and often added to yogurt, so it is very beneficial to the body to eat some often.

Lactic acid bacteria are a type of fungus that cleanses the intestines.

The role of lactic acid bacteria.

If a large number of lactic acid bacteria accumulate in the intestines, then the neutral bacteria will also be affected by the lactic acid bacteria and become allies of our intestines, making the intestinal environment healthier. However, each strain has its own unique properties, and whether it can survive in your own intestines, which means that it is important to find lactic acid bacteria that are suitable for your intestinal environment.

Many people with constipation problems will say that they often eat yogurt for intestinal health and constipation when they go to the hospital for examination, but they don't know whether the yogurt they are ingesting has an effect on their intestinal environment.

Depending on the symptoms reflected by each person's intestinal environment, the types of lactic acid bacteria that should be ingested are different. The lactic acid bacteria contained in yogurt can regulate the intestinal environment, but the effect varies from person to person, and there are also people who cannot improve constipation by ingesting yogurt. Especially for chronic constipation in elderly patients, it is difficult to improve it with yogurt.

Even if lactic acid bacteria are ingested, if they are not suitable for their intestinal environment, they will be excreted directly before they can be effective. Moreover, the ingested lactic acid bacteria can only survive for about 1 week when they reach the intestines, so it is necessary to verify whether this kind of lactic acid bacteria is suitable for their intestines, and it is recommended to consume 100 200g of yogurt a day and insist on continuous intake for at least a week to verify.

Lactobacillus drinks are not good for the stomach and intestines, so it is not recommended to consume them regularly. Many people think that lactobacillus drinks can promote digestion, regulate intestinal flora, and are good for gastrointestinal health, but this perception is a misconception. Lactic acid bacteria can indeed play such a role, but lactic acid bacteria drinks are not equal to lactic acid bacteria.

What are the effects of lactic acid bacteria on the stomach Core tips: Lactic acid bacteria are mostly substances contained in yogurt, which are very good for health, and you can drink more at ordinary times, which has a lot of effects on the stomach and intestines, and can help improve constipation, diarrhea and other symptoms caused by gastrointestinal discomfort

What are the benefits of lactic acid bacteria to the human body? Its main function is to break down lactose and protein to aid digestion and absorption. For example:

Some people have diarrhea as soon as they drink milk, precisely because the body lacks an enzyme that specializes in metabolizing lactose in milk; However, after fermented milk, the lactose in it has been broken down by lactic acid bacteria and does not cause diarrhea, so people who cannot drink milk can eat more yogurt or fermented milk. At the same time, when lactic acid bacteria turn milk sour, it is also more conducive to the absorption of calcium in milk by the stomach and intestines. Secondly, in our gastrointestinal tract, there are many bacteria, some beneficial and some harmful; Lactic acid bacteria can increase the number of beneficial bacteria in it and inhibit the growth of harmful bacteria, so as to reduce the production of toxins, thereby strengthening the gastrointestinal tract and preventing chronic diseases.

In addition, lactic acid bacteria also have the function of promoting gastrointestinal peristalsis, so it is conducive to improving the phenomenon of habitual constipation in middle-aged and elderly people. In addition, after lactic acid bacteria are fermented in the intestines, B vitamins will be produced, which is beneficial to health. But why is there any emphasis on active lactic acid bacteria?

The main reason is that live lactic acid bacteria can help digestion after fermenting milk, and at the same time, when these bacteria enter the human body, they can also play a role in strengthening the stomach and intestines; However, due to the presence of live bacteria, it cannot be stored at room temperature for too long, so generally products containing live lactic acid bacteria must be refrigerated. As for the fermented milk on the market, it is sterilized after the milk is fermented to kill the lactic acid bacteria in order to increase the shelf life; However, because it does not contain live bacteria, although this kind of product can help digestion, it does not have the function of strengthening the stomach and intestines. Many people have also noticed that some yogurt also has added fructo-oligosaccharides and emphasizes more benefits.

This is because the lactic acid bacteria in yogurt can only survive in the gastrointestinal tract for a short time and cannot continue to work; Fructo-oligosaccharides can provide nutrients for the growth of beneficial bacteria in the body and conditions for reproduction, so that the active function of bacteria can be exerted to the extreme. Therefore, the addition of fructo-oligosaccharides to yogurt is indeed conducive to the survival of lactic acid bacteria in the stomach and intestines, and it is also more conducive to strengthening the stomach and intestines. It can be seen that not all bacteria are harmful to the human body, for example, lactic acid bacteria are good helpers for health; In addition to having good nutritional value, lactic acid bacteria foods are out-and-out healthy foods.

Especially for people who are recovering from a serious illness and taking more antibiotics, because the bacteria in the digestive tract will be killed by the drugs, which will affect the production of vitamins in group B, they should eat more yogurt. However, it should be reminded that although most of these foods are made from low-fat fresh milk, they also contain a lot of sugar, so you should be careful when eating them to avoid getting fat by consuming too much caroli.

Efficacy of lactic acid bacteria.

Aids digestion and keeps the gut healthy:

Lactic acid bacteria can help digestion and adjust the peristalsis of the large and small intestines to facilitate the normal functioning of the intestines. In addition, lactic acid can also help with calcium absorption.

Prevent diarrhea: When traveling, it is often caused by diarrhea or vomiting due to water and soil adaptation, you can take lactic acid bacteria food when you go out; Or the diarrhea caused by the destruction of the original balance of the intestinal flora ecology can also be supplemented with a large number of lactic acid bacteria to maintain the balance of the flora ecology in the body.

Cancer prevention: Lactic acid bacteria grow in the gastrointestinal tract, and due to the anti-antagonism of the microbial community, the number of undesirable bacteria that produce carcinogens will be greatly reduced, thereby reducing the chance of cancer.

Eliminate constipation: The lactic acid secreted by lactic acid bacteria can increase the peristalsis of the large and small intestines, and the effect is mild and natural, which is different from the laxatives on the market.

Manufacture of vitamins:

Lactic acid bacteria can produce vitamins needed by the human body in the intestines, such as vitamins K, B2, B6, B12, folic acid, etc.

Among the lactic acid bacteria, Lactobacillus acidophilus and Lactobacillus bifidophilus have the most significant impact on the human body, their main function is to promote immune regulation, enhance the body's resistance to intestinal infection, reduce diarrhea, and help to produce vitamin B complex and K, and enhance the absorption of calcium, iron, potassium, etc.

Products containing lactic acid bacteria on the market generally refer to fermented milk with beneficial bacteria, which is mainly made by using the ingredients and sugars in milk through the process of lactic acid bacteria fermentation. Most of these products emphasize the need to help and maintain the balance of beneficial bacteria in the human body to achieve health.

The fermentation of lactic acid bacteria can decompose the lactose of milk to only 20% to 30% of its original content, so people who drink milk and have diarrhea can use this type of lactic acid drink instead of cow's milk and absorb the same nutrients.

In addition, because the casein and fat in lactic acid bacteria milk become more digestible, it also helps the calcium and lactic acid in the milk to be absorbed more easily after combining, so that the intestinal environment is acidic due to the influence of lactic acid, which is helpful for digestion and stomach and intestine rectification.
