[0002] The intestinal flora, also known as the intestinal microbiome, refers to the various microbial communities that live in the intestines, including bacteria, fungi, viruses and other microorganisms. These microorganisms play an important role in maintaining human health, digesting food, synthesizing vitamins, protecting the immune system, etc. The composition of the intestinal flora is affected by many factors, including diet, age, genetics, environment, lifestyle, and the use of antibiotics. An imbalance in the intestinal flora (i.e. "dysbiosis") is associated with a variety of health problems, including obesity, diabetes, inflammatory bowel disease, allergies, depression, etc. In recent years, more and more research has been done on the intestinal flora, and scientists are exploring its role in health and disease in order to provide new directions for disease prevention and treatment.
