In recent years, it has been reported that the small intestine accounts for 70 percent of the immune function, while the large intestine accounts for 10 percent, that is, nearly 80 percent of the immune function in the intestine (that is, in the intestine containing the small intestinal mucosa). Although this term has not been known before, but the recent immunology, small intestinal mucosa has been “immune New World” or “immune New World” title.
It is often said that the small intestine is “inside out”. It’s inside the body, but it’s actually connected to the outside world. It is well known that the mucous membranes in the mouth and nose are actually connected to the anus through the throat, bronchi, respiratory organs, and even the esophagus, stomach, small intestine, and large intestine. So, from the point of view of the body’s protection through the mucous membrane, the small intestine is actually in contact with the outside world.
Accordingly, intestinal tract is the place that can absorb body to need nutrient not only, also be the barrier that a block at the same time, in order to prevent the invasion of foreign body, pathogen and harmful material, develop resistance is very must.
The length of the small intestine is about seven meters, and the mucosal area of an adult is about the size of one to five tennis courts, indicating its importance. In fact, most of the immune function is concentrated in the “gut”, and it is used to deal with invaders.
However, studies have shown that up to 98 percent of the immune system is asleep and not fully functioning due to a lack of good bacteria in the gut. You have to have lots of good bacteria in your gut for all your immune functions to become active.
Because of this, if you want to improve your immunity, you must increase the number of good bacteria in your gut and make your gut environment better.
Therefore, dietary fiber and enzymes become very important.
The key to good health is the gut.
Increase good bacteria, regulate the intestinal environment.
The more good bacteria in your body, the higher your immunity
The most important thing you can do to keep your gut healthy is increase the number of good bacteria in it. The so-called good bacteria, is lactobacillus and Bifidobacteria, they will deal with harmful bacteria from the outside into the function of enhancing immunity.
On the other hand, bad bacteria, such as Clostridium wilfordii or Staphylococcus, can rot the gut environment, producing carcinogens, toxins and other harmful substances that weaken the body’s defenses.
Continuous ingestion of indigestible food, or frequent overfilling of three meals, can increase the number of bad bacteria in the gut. The total amount of bacteria in the gut is usually fixed, and when the number of good bacteria increases, the number of bad bacteria decreases. However, it is possible that the number of bad bacteria increases and the number of good bacteria decreases.
As people get older, cancer and diseases of modern civilization are more likely to occur. The reason is that good bacteria tend to become less common as we get older, and it turns out that older people’s gut bacteria tend to turn into putrid bacteria, or bad bacteria. Babies are born with a lot of good bacteria in their intestines, and bifidobacteria, the representative of good bacteria, will rapidly decrease from the age of about 40 in humans, making the intestinal immunity decline.
If the harmful substances produced by the bad bacteria are absorbed by the intestines, the blood will be contaminated and become the cause of chronic fatigue and rough skin, or liver function problems, which are more related to the aging of the whole body, such as high blood pressure and arteriosclerosis.
Conversely, even with age, the good bacteria in your gut are at an advantage, and you can live longer and healthier lives. As we mentioned earlier, most of the immunity is in the gut. If this is combined with a balance of good and bad bacteria in the gut, immunity is enhanced. In other words, no matter how uncomfortable you feel, you can recover slowly.
If you eat too much or some food that is not easy to digest, your intestinal immunity will become weaker and weaker.
