There is no such thing as gastrointestinal detoxification. People can effectively maintain good health by maintaining good gastrointestinal activity in their daily lives. The main methods are diet, exercise and probiotic supplementation. It is recommended to take treatment under the guidance of a doctor. 1. Diet: People can take in fiber-rich vegetables (such as sweet potatoes, celery, etc.) in their daily life to promote defecation, thus playing an auxiliary role for good gastrointestinal tract activity. Avoid overeating, do not eat spicy greasy and other indigestible food. 2. Exercise: People can do aerobic exercise (such as swimming, jogging, etc.) to promote gastrointestinal peristalsis and accelerate excretion, so that the substances accumulated in the gastrointestinal tract can be discharged from the body when the physical condition permits. 3. Supplement probiotics: People can supplement some probiotics to improve intestinal flora, increase gastric motility, and promote the expulsion of substances from the gastrointestinal tract.
