Crohn's disease is a chronic nonspecific inflammatory bowel disease of unknown cause. Its lesions can occur in any part of the digestive tract. The main symptoms include abdominal pain, diarrhea, abdominal masses, fistula formation, and weight loss. Systemic symptoms such as fever and malnutrition can also occur, and intestinal obstruction might require surgical treatment. Currently, there are no specific treatments for this disease, and it has signs of lifelong recurrence, making the treatment very challenging. It is crucial to pay attention to nutrition in the diet, consuming high-nutrition, low-residue foods, and appropriately supplementing with folic acid, vitamins, and other nutrients. The diet should primarily consist of rice and noodles, and it is advisable to consume lean meats, fish, poultry, eggs, and soy products. Peanuts can be eaten in small amounts, but it is not recommended to consume them excessively because they have a high fat content, which is not beneficial for managing Crohn's disease.
