How the intestines affect the whole body?
Trillions of bacteria live in the intestines, which interact with all the organs of the body. In recent years, scientists have realized what effect the intestines have on our well-being. It turns out that the digestive system is responsible for the health of many organs — from the skin to the kidneys. And it looks like it's all about bacteria.
1. The intestines can ruin the skin
Rash, dryness, peeling affect the skin and spoil the appearance. But at the same time, they indicate problems with the digestive system. Like many other organs, the skin can respond to intestinal problems, and a rash — the most common reaction.
The fact is that eczema, redness and a rash — it is an immune response to what is in our gut. Most often, certain foods trigger such an allergic response. It is enough to exclude them from the diet so that the rash goes away.
But on acne, contrary to popular belief, the diet has almost no effect.
2. Intestine affects brain function
The brain seems to be independent of the intestines. But actually, these bodies interact.
- Intestinal cells produce the hormone serotonin, which affects many processes, and is best known as mood hormone.
- The intestinal microflora is involved in the production of cytokines — these are proteins of the immune system that affect, among other things, the brain.
- Microbes in the intestines produce substances that affect the blood-brain barrier. Roughly speaking, this is a filter between the brain and the circulatory system that protects the brain from all the harmful things in the blood.
Research is underway on how gut microbes affect the nervous system. This is a complex process that has not yet been fully studied, but it is already clearly clear: for the head to be clear, you need a healthy intestine. While scientists are looking for how to use this connection with health benefits, we can think about ourselves and still start eating fresh vegetable salads every day so that the intestines work better.
3. The intestines affect immunity
A huge amount of proteins and pathogens alien to us enters the intestines every day with food. — substances that can cause disease. Therefore, the intestine has adapted to neutralize these very substances as quickly as possible. This microflora lives in it.
A poorly functioning intestine can lead to asthma, migraines, allergies, and even autoimmune diseases (these are diseases in which cells of the immune system attack their own body).
4. Intestine affects the kidneys
The kidneys and large intestine help regulate the water-salt balance in the body. The kidneys also cleanse the body of water-soluble toxins that could enter the bloodstream from the intestines or as a result of the vital activity of bacteria in our gastrointestinal tract.
Therefore, if the intestinal mucosa is damaged, it can harm the kidneys. This happens, for example, after taking certain antibiotics, due to diseases like irritable bowel syndrome. When the mucous membrane does not work well, the amount of harmful substances that enter the bloodstream from the intestines grows, which means that the immune response is enhanced. All this leads to a systemic inflammatory process that affects the kidneys, including the development of chronic renal failure.
5. Intestine affects liver health
Like the kidneys, the liver is responsible for cleansing the body. Everything that enters the bloodstream from the intestines will end up in the liver.
All substances, including hormones, toxins, medications and decay products, pass through the liver to enter the intestines along with bile, from where it is easier to remove. Changes in the normal functioning of the intestine and in the integrity of the intestinal membrane can lead to chronic liver diseases and even a change in its structure, for example, fibrosis, in which normal organ tissue is replaced by inactive connective tissue.
6. Our weight depends on the intestines
It is clear that weight depends on what we eat. But also from bacteria in the intestines, perhaps, too. So that we can gain weight, we need more nutrients. The intestines share food for these substances. Depending on which bacteria there are more in it, it can process more or less food eaten. Therefore, you need to feed not only yourself but also bacteria.
How to help your intestines
The beneficial bacteria discussed above, — these are probiotics. They live in our intestines by themselves in sufficient quantities. But for them to work well, they need «feed». A breeding ground for these bacteria — prebiotics, products with plant fibers, thanks to which the microbiome remains healthy.
To get both that and another, it is not necessary to attack pharmacy preparations. You need to adjust your diet according to very simple principles:
- Eat more fresh vegetables.
- Snack with natural yogurt and kefir.
- Love fermented snacks: sauerkraut or kimchi.
- And all this — instead of sugar and refined carbohydrates, such as, for example, in wheat bread.
