Food intolerances , unlike food allergies, don't involve the immune system and the release of histamine.
Food intolerances are actually much more common than food allergies.
But because many of the symptoms are the same, it can be difficult to tell which condition you have. A physician who is certified by the American Board of Allergy and Immunology can help you determine whether you have an allergy or an intolerance.
