Crohn's disease is a chronic nonspecific inflammatory disease, with main symptoms including abdominal pain, diarrhea, weight loss, and abdominal masses. A characteristic of the disease is that it is difficult to treat, and there are signs of lifelong recurrence. During a colonoscopy, longitudinal, deep ulcers can be observed on the intestinal mucosa, which can raise suspicion of Crohn's disease. Moreover, lesions from Crohn's disease can appear throughout the digestive tract, so it is crucial to be mindful of one's diet. It is essential to consume easily digestible foods, such as porridge, soup, and well-cooked noodles, and meats should be stewed until very tender to ease the burden on the digestive system. Fruit intake should be limited, but if necessary, more digestible fruits such as bananas and dragon fruit can be consumed in moderation, while other fruits are not recommended.
