Do you know the existence of “excrement bank”? Open biome in the United States is such a company. The staff of this bank will strictly screen every person who donates faeces, and only about 0.5% of the talents can be selected. After being selected, you can get a reward of $40 for each sample provided.
After that, the bank staff will freeze the samples for preservation. From the current clinical data, the effect of these frozen samples in the treatment of Clostridium difficile infection is very strong. Some clinicians even freeze-dried the samples to make fecal bacteria capsules.
Intestinal microflora is a mysterious field that human medicine does not know much about. This field is even more mysterious than our brain. More and more scientists and doctors call our gut “the second brain”. Simple fecal transplantation will also show some mysterious phenomena like brain transplantation.
Scientists have found that the first mysterious phenomenon is that FMT can treat autism. According to the traditional concept, autism is a mental disease because of brain problems. However, after changing the intestinal flora environment, the mental problems in the brain have been cured. Does intestinal flora control the human spiritual world?
The second mysterious phenomenon is that after FMT, some people will completely change, from character to body shape, and then to the way of speaking, almost all of them, just like a new brain.
In the book, the author of hub brain shares a real case he received. A mother in her 50s received a fecal transplant from her daughter because of intestinal problems. Before the transplant, her mother was a long-term healthy dieter, maintained proper movement all the year round, and was always slim. Her daughter, like all young people, likes to eat high calorie and high-fat food, but she is also very healthy, just a little fat.
After the transplantation, the mother began to become more and more like her daughter, like eating chocolate, the body began to get fat, the character became more enthusiastic, and even the way of speaking with some young people’s unique vocabulary.
Why is this so? Although it’s inconceivable, scientists still give two surprises about the intestinal flora.
Surprise 1: sharing body
Our body is actually shared with all kinds of bacteria. The total number of all kinds of bacteria in the human body is about 1.3 times that of human cells, which is 10 times under another measurement standard. On the other hand, of all the genes expressed in the human body, less than 1% belong to human genes. There are about 80 trillion bacteria living in our intestines.
They are not simple parasites, but like the brain, they give orders to every organ of our body, even the brain above your head. Your thoughts and feelings are also controlled by these bacteria.
When many people first hear this idea, they will feel incredible, but if you think about it, when you are very hungry, are you in a bad mood, and it’s easy to get mad. Then, when you eat some specific food, such as chocolate, fat mutton, big nuts, you will immediately feel happy.
Scientific research shows that this process is not that your brain is controlling your gut, but that your gut is telling the brain how it feels, allowing the brain to share its pain and try to solve it as soon as possible. The traditional idea is that the vagus nerve of the brain connects various organs and gives them orders to complete their work.
However, studies in recent years have shown that 80% ~ 90% of the vagus nerve connecting the brain and intestine is reverse, which is the channel that sends instructions from the intestine to the brain. In other words, our body is jointly managed with our intestinal flora. It is not only the body on the physical level, but also the subjective things such as thoughts, emotions or souls, which live in the brain and intestines.
Looking back at the theory of soul, soul and spirit of traditional Chinese medicine and Taoism, it turns out that it is exactly the same as the theory of the second brain of intestine.
Surprise 2: 500 million neurons
Neurons are not exclusive to the brain. There are 100 billion neurons in the brain and 500 million in the intestine. The feeling is 200 times worse, and the thinking ability of the intestine is weak. However, there are only 500 million neurons in the dog’s brain. So in theory, your gut is as smart as your dog.
Scientists have been working on a strange subject for the last year or two, and they have found that removing the vagus nerve from the gut to the brain can prevent mice from developing Parkinson’s disease. Although the experiment has not been clinically tested, autopsies of Parkinson’s patients by scientists have found that Parkinson’s disease is most likely due to the presence of pathogens in the gut.
The pathogen is a misfolded protein, which may be a prion. After it appears in the gut, it spreads to the brain through the vagus nerve, making the brain sick and dementia.
