According to a recent study from the Journal of the American Medical Association , the prevalence of food allergy may be overestimated.  While allergists in the United States would agree that food allergy issues seem to be increasing, most would also point out that much of what people consider "food allergy" may instead be a food intolerance or non-allergic issue.  Yet, food allergy remains an important problem in children and adults, and can be life threatening.  Methods of testing for food allergies have their limits.  Allergists can help determine whether the problem is occurring on an allergic basis.  Or not.
