i just bought a book last night called feeding the bump and it says that the following foods are digestive aids:

- bitter foods such as rocket and watercress
- mint in all forms
- fennel
- ginger
- cumin, cardamon, tumeric and caraway spices
- banana, apple, pineapple, paw paw, papaya, tomato, carrot and celery
- chamomile tea
- milk and yoghurt

hope that helps a bit !?!
