People with Crohn's disease should avoid strenuous exercise in daily life and instead engage in moderate physical activities within their capabilities. They should not overeat but eat small, frequent meals of easily digestible food. Avoid spicy and irritating foods such as strong tea, spirits, coffee, chili peppers, mustard, etc., and try to eliminate them from the diet. Additionally, avoid staying up late and eating overly coarse foods. It is beneficial to consume more fresh vegetables and fruits that are rich in vitamins, such as apples, bananas, and watermelons.
