The importance of intestinal microecology is many, including maintaining normal immune function, regulating nutritional metabolism in the intestinal tract, and promoting normal development of the brain and nervous system. 1. Maintaining normal immune function: there are beneficial bacteria, harmful bacteria and conditionally pathogenic bacteria in the intestinal tract, when the intestinal flora is in a balanced state, the human body’s immunity is normal. Once the intestinal flora is out of balance, there are too many harmful bacteria and the immunity is out of balance, which can cause various immune diseases. 2. Regulate nutritional metabolism: intestinal flora can decompose intestinal contents into micro-nutrients, which is beneficial to human absorption. Animal experiments and clinical evidence have shown that intestinal flora imbalance can trigger the occurrence of obesity, diabetes, cardiovascular and cerebrovascular diseases and other metabolic diseases. 3. Promote the normal development of the brain and nervous system: normal intestinal flora can metabolize nutrients needed by the brain and nervous system, such as aminobutyric acid, etc., which is a human being to maintain a good mood, intestinal dysbiosis not only loses the function, but on the contrary, it also produces a large number of enterotoxins, which can induce depression, Parkinson’s disease and autism. Intestinal microecology has an important role in human health, so you can take some probiotics under the guidance of the doctor, follow the doctor’s instructions to regulate their own intestinal microecology, to maintain their own health status.
