In addition, the intestine controls important metabolic processes. And it is a vital component of our immune system - about 80 percent of the immune cells of the human body are located in the intestine. There is a connection between our digestive tract and our psyche, which is also reflected in expressions such as "that hits me on the stomach" or "that causes me stomach pain". Our "abdominal-brain" contains an estimated 100 million nerve cells - more than in the spinal cord. The happiness hormone serotonin is also produced here and 95% of it is permanently in our stomach.
