Crohn's disease is a chronic non-specific inflammatory disease, the main symptoms of which include abdominal pain, diarrhea, weight loss, and abdominal masses. This disease is characterized by its difficult treatment, high propensity for relapse, and signs of lifelong recurrence. During colonoscopy, longitudinal and deep ulcers can be observed on the intestinal mucosa, which may indicate Crohn's disease, and these ulcers can appear throughout the gastrointestinal tract. Therefore, dietary precautions are essential. The diet should be easily digestible, and smoking and alcohol should be avoided. It is also advised to avoid strong tea, coffee, greasy, fried, barbecued, spicy, raw and cold foods, as well as sweets. It is preferable to consume porridge mainly, drink soup, or eat well-cooked noodles, and any type of meat should be thoroughly stewed before consumption.
