Food Intolerance Diagnostics is a growing international and collaborative effort to provide information, diagnostic services and treatment to individuals with adverse reactions to food. On the other hand, we have a strong research and clinical interest in the beneficial effects of food and natural nutrition.


We are a network of experienced physicians and dieticians with different clinical backgrounds and expertise, and all have a special interest in food-related reactions. The services are coordinated by Dr. Clive Wilder-Smith, specialist gastroenterologist and academic researcher. Our testing hubs are located in Australia, Singapore, South Africa and Switzerland.
