'Food allergy / intolerance testing' in dermatology : science or hype?

Abstract

Food allergies are becoming an increasingly recognized clinical problem and patients frequently ask if their health complaints are related to their diet. There has been a recent phenomenon of food allergy or intolerance testing leading to dietary alterations and restrictions. This article gives a brief overview of the latest evidence and current guidelines for proper diagnosis and management. A distinction between food allergies and food intolerance or sensitivity should be made. It focuses on the association of the common skin conditions: eczema, acne and urticaria, to food and whether dietary changes are indicated. The currently available tests and their appropriateness are also discussed.
