A person with a healthy digestive system will experience far less bloating, even with foods that commonly cause bloating. However, the list of foods below commonly causes bloating in many people. Raffinose - a sugar found in beans, cabbage, Brussels sprouts, broccoli, asparagus, other vegetables and whole grains. Eaten raw, these foods cause more bloating than when they are cooked. Lactose - a natural sugar found mainly in milk and milk products, such as cheese, cream, yoghurt and ice cream. Lactose levels are much higher in milk and non-fat milk than in cheese and yogurt.
