Diarrhea patients can eat vegetables with less fiber, such as Chinese cabbage and broccoli, but they need to avoid eating vegetables with more dietary fiber, such as celery, because vegetables with more dietary fiber may promote intestinal peristalsis and aggravate diarrhea symptoms.

Diarrhea patients can eat some green vegetables properly, because green vegetables contain a lot of vitamins and water, which can supplement the water and nutrition lost by diarrhea and relieve diarrhea symptoms. In addition, vegetables are easier to digest and can regulate the function of gastrointestinal tract.
