Food Hypersensitivity

Intolerance or Allergy?
The terms intolerance and allergy are often used and often incorrectly used interchangeably. They have different meanings for different people. A new way of classifying food intolerance and food allergy has been suggested.

How do you define allergy and intolerance?

Food Allergy
An undesirable immune reaction to a component in food e.g. a food protein, that would not affect a non-allergic individual.

Food Intolerance
A reaction to a food that does not involve an immune response.



The European Academy of Allergology and Clinical Immunology (EAACI), an expert body on allergy has recently proposed that the term food hypersensitivity be used as an umbrella term to both allergic and non-allergic reactions.
