What are intestinal bacteria, and why are they important?

Intestinal bacteria are bacteria that live within the digestive system of all animals, including humans. We have learned that these bacteria are crucial to our health, both physical and mental. They help us digest food, provide nutrients, and help us fight disease bacteria.

Simply put, intestinal bacteria, also known as the microbiote of the intestine,

Where does it start?

When the children are still in the womb, the bacteria begin to colonize and form settlements in their intestines.

After the birth of the child, more bacteria enter the intestine, especially during childbirth. During delivery, bacteria present in the mother ' s vagina enter the child ' s mouth and attempt to establish themselves there. In fact, children born by caesarean section have a different microbio of the intestine from the microbiotes of their natural peers.

Unfortunately, all bacteria that get into a baby's intestine are not good, and sometimes even bad bacteria that cause disease can get there. But there's a simple solution: breast milk. The breast milk of a mother contains everything the child needs to grow up big and strong.

One of the components of breast milk is antibodies. When children are born, their immune system is not sufficiently developed. These antibodies protect newly born children until their immune system learns to fight for itself. One of the ways they do it is to combine with good bacteria to combat bad bacteria and prevent them from forming into a baby's bowel.

In addition, breast milk contains oligosacharids of breast milk, which are sugar molecules designed to stimulate the good growth of intestinal bacteria, a natural prebiotic that helps to increase the population of bifidobacteria — bacteria that are mostly present in the intestines of a child.

When a child grows up and eats solid food, intestinal bacteria start to "fun." All these new products bring new and new intestinal bacteria into the baby's body, where they can mix with each other. New foods also bring in new nutrients that support the growth of these different intestinal bacteria. That's why healthy nutrition is so important. Even research shows that the use of too much unhealthy unhealthy food causes imbalances in our intestinal bacteria.

The new types of bacteria that start to feel at home are Bacteroids, Ruminococcus and Clostridium. Then, when children turn three, their intestines calm down and become like adults.

The whole point is that intestinal bacteria contain enzymes that help to break up undigested foods and produce vitamins that we can't afford without intestinal bacteria. Without intestinal bacteria, our body would suffer from vitamin deficiency, stomach ingestion and growth defects.

What other processes are intestinal bacteria involved?

We just talked about intestinal bacteria helping digestion, but they don't just do it when they're young, and throughout our lives, intestinal bacteria help digest food.

We have to thank our intestinal bacteria, because these vitamins are needed to keep our body healthy.

But how do intestinal bacteria perform such useful tasks? They have genes for this, and all these genes are what we know as a microbe of the intestinal, and it's interesting that more than 99% of the genes in our body are microbial.


In addition to digestion, intestinal bacteria also play a role in our sleep cycle, and research has shown that intestinal bacteria excrete sleeping compounds called muramyl peptides.

Other studies have shown that people with insomnia experience changes in intestinal bacteria.

Some intestinal bacteria, such as Corynebacterium, feed on the food we eat, produce metabolites such as serotonin. The produced serotonin goes into the bloodstream and interacts with the nervous system, giving the brain a signal to control the sleep/rehearsal cycle.

If, for an unknown reason, you suffer from poor sleep quality, it may be related to the disruption of intestinal bacteria.

Brain intestinal axis

In addition to helping us digest food and sleep well, it also interacts with the brain. That's how all the microbial intestines are on the fast set of our brain number and help coordinate the functions of our body. It's known as the intestine brain. It's a two-way link between the central and the enternal nervous system that allows the gastrointestinal tract and the brain to communicate with each other to control the homostasis.

The neurons in the LPC send signals to the brain, coordinating physiological functions and even immune responses to germs, so intestinal bacteria can influence how we behave, think and interact.

One study, using special female mice without intestinal bacteria, showed that they had a lower level of anxiety when they were in mazes; however, males had a stronger reaction to stress; this led scientists to believe that the axis of the intestinal brain varied according to sex.

So, depending on how healthy our intestinal bacteria are, they can affect the brain signals by influencing our hormonal reactions, which is why sometimes when you have indigestion or stomach problems, you can feel a lot of anxiety or annoyance.

How can we increase the number of good intestinal bacteria?

In addition to maintaining healthy diets, we can help strengthen good intestinal bacteria by two means: probiotics and prebiotics.

Probiotics are basically good bacteria that we put into our body, and in sufficient quantity to have a beneficial effect, such as the Bifidobacterium species and other types of acidic bacteria, which can be consumed by taking capsules or using experimental products such as cheese, yogurt, and other products rich in bacteria.

Prebiotics are a little different. They're products that are used by good intestinal bacteria to accelerate their growth and reinforcement. Like any other living organism, intestinal bacteria like varnishes. By giving them prebiotics such as inulin, fructooligosaharids, or halactoligosaharids, you contribute to a better growth of good intestinal bacteria.

However, before you try any of these two drugs, you need to consult a doctor to find out which probiotics or prebiotics fit you.

I hope now you're beginning to understand how important intestinal bacteria are to us, and these are not just microorganisms that help us digest food, they help control the functions of our body in unbelievable ways. Research shows the link between intestinal bacteria and neurological diseases, such as Alzheimer's disease and autism.

That's why so much research is devoted to better understanding of the intestinal-brain relationships. Previously, brain disorders were thought to be incurable, but now there's hope that we can treat these diseases by changing intestinal bacteria.

Our intestinal bacteria do so much for our body that we still don't understand much, but clearly, by optimizing the relationship between our body and intestinal bacteria, we can become mentally and physically stronger.
