There is currently no way to diagnose food intolerances, and therefore an elimination diet and re-challenge are required.  Depending on your symptoms, our dietitian can help guide you through a low FODMAP diet, or a food chemical elimination diet.  It can be extremely difficult to pinpoint the cause of your symptoms given food contains a variety of different components (both fodmaps and food chemicals).  Given the complexities and restrictive nature of these diets it is strongly recommended to work though both elimination and re-challenges with our dietitian, who can then help you to work out a long-term plan to suit your needs.
