18.55 years old, the intestine began to age?
Description: After we entered the age of 55, the number of beneficial bacteria in the intestine began to decrease greatly. Lin Sanren, director of the Department of Gastroenterology, Peking University Third Hospital, believes that the change of flora is only one of the factors affecting intestinal health. The gastrointestinal tract is also the largest "emotional organ" of human beings, and psychological disorders can easily cause gastrointestinal discomfort. It is debatable to say that aging begins at 55.
Protection: to achieve "two connections", one is to ensure that the digestive tract must be connected from the exit to the entrance. The second is to maintain a happy mood and a smooth mood. Of course, some tips can also help maintain the stomach, such as chewing slowly and increasing the intake of dietary fiber.
