ecological balance, but micro-ecological balance is far from receiving the attention it deserves. Understanding the importance of the micro-ecological balance of the human body and maintaining the micro-ecological balance can enable human beings to adapt to the large environment externally, adapt to the micro-environment internally, and maintain the unity of life and environment. The human micro-ecological system mainly includes 5 ecological areas of oral cavity, respiratory tract, gastrointestinal tract, urinary tract and skin. The gastrointestinal microecosystem is the most important part of human microecology, and it is also the largest and most complex microecosystem. The gastrointestinal ecological space consists of the esophagus, stomach, small intestine, and large intestine. The total number of bacteria is 1014 colony forming units (CFU), which is nearly 10 times the number of human somatic cells.
More than 70 years ago, Dr. Yoshida Yoyo of Kyoto University in Japan put forward the term “good intestine and longevity”. If the micro-ecological environment in the intestine changes, the flora will be imbalanced and harmful bacteria will increase. The intestines age, and the “intestinal age” is much greater than the actual age. One of the causes of human aging is directly related to intestinal aging: harmful bacteria in the large intestine catabolize food residues, produce harmful toxins, poison the body, and lead to aging. For human health and longevity, aging should be prevented in the intestines.
