In the 21st century, people’s standard of living has become richer, but their diets have become more and more irregular, making the intestinal function recede significantly, and intestinal-related diseases have become more and more serious. Many people are already suffering from constipation, and the age range is large, and constipation is becoming more and more serious at a younger age. Thirty-five percent of people often have flatulence problems, 10% have gastric ulcers and duodenal ulcers, 15% have irritable bowel syndrome, and many people’s intestines are like a polluted river, muddy. The aging of the intestine accelerates the aging of the body. In order to stay young and beautiful for a long time, we must keep track of our intestinal health. The human digestive tract is about 9 meters (mouth —- anus): the esophagus from the mouth to the stomach is about 30 cm, the small intestine is about 6 meters (normally contracted to 2 to 3 meters), and the large intestine is about 1.6 meters.
