Deep relationship between intestines and allergies

The intestines are not only food, but also places where pathogens and viruses enter. Therefore, there are a large number of immune cells in the intestine that repel foreign enemies such as pathogens and viruses. Immune cells are densely packed inside the intestinal wall that absorbs nutrients and water, preparing for the invasion of foreign enemies.

In addition, a part of the wall of the small intestine called Peyer's patch deliberately draws foreign enemies into the body and makes them touch immune cells, learning the characteristics of enemies that are harmful to the human body and should be attacked.

In this way, the intestine has an important role in training immune cells and preparing for the invasion of foreign enemies. In addition, immune cells are carried to the whole body on the blood and fight off invading pathogens and viruses in various parts of the body.

However, if the number and quality of immune cells are out of balance or runaway for some reason, you will end up with diseases such as allergies and autoimmune diseases. There are many other illnesses that seem to have nothing to do with the intestines and are closely linked.

About 70% of immune cells are in the intestine

When pathogens and viruses enter the body, immunity counteracts them. About 70% of immune cells that play such an important role are present in the intestine. In other words, improving the intestinal environment is of utmost importance in order to maximize the function of immunity.

When the intestines are healthy, that is, when the number of good bacteria in the intestines is high, immune cells can be actively activated. On the other hand, if the number of bad bacteria is high, nutrients will not be distributed throughout the body. Bad bacteria feed on animal proteins and produce toxins such as hydrogen sulfide, indole, skatole, and ammonia, which reduces the digestive and absorptive power of the intestines. When the intestinal environment deteriorates, the physical condition may change, such as constipation, diarrhea, and stool odor. Therefore, if you start to see these symptoms, you can think that the number of bad bacteria in your intestines has increased.

Conversely, preventing these symptoms will increase the number of good bacteria in the intestines and prevent allergies.

Runaway immune cells

In recent years, the symptom that the immune cells of the intestine that protect the body run away and attack other than the external is increasing rapidly. This is a disease called allergies or autoimmune diseases. Recent studies have shown that these diseases are closely associated with gut microbiota abnormalities.

Examination of patients with severe allergies and autoimmune diseases reveals that certain immune cells are significantly reduced. That is the immune cell called "Treg". It has the role of braking the immune cells that attack foreign enemies that have invaded the body. Therefore, when the number of T-legs decreases, immune cells attack non-external substances, causing allergies and autoimmune diseases.

T-legs are increased by dietary fiber and activate their function. Therefore, it is no exaggeration to say that dietary fiber holds the key to preventing these diseases.
