People with special physique should not eat cold, spicy and irritating food, nor should they eat too greasy food. Onions, potatoes, sticky cakes, peppers and carbonated drinks are easy to cause flatulence in the gastrointestinal tract, so you can eat less or not at ordinary times. Usually, you can eat more nutritious and digestible food to enhance your physique and improve your immunity.
