Food allergens and intolerance

Title : Food allergens and intolerance

Abstract:

Adverse reactions to foods, aside from those considered toxic, are caused by a particular individual intolerance towards commonly tolerated foods. Intolerance derived from an immunological mechanism is referred to as Food Allergy, the non-immunological form is called Food Intolerance. IgE-mediated food allergy is the most common and dangerous type of adverse food reaction. It is initiated by an impairment of normal Oral Tolerance to food in predisposed individuals). Food allergy produces respiratory, gastrointestinal, cutaneous and cardiovascular symptoms but often generalized, life-threatening symptoms manifest at a rapid rate-anaphylactic shock. Specific food intolerance needs to be distinguished as those who are affected have an aversion to numerous foods. Even in cases where specific food intolerance can be demonstrated, the diagnosis of food allergy depends on additional evidence that the patient's reaction is based on an abnormal immunological response. It is difficult to show a connection between individual foods and an allergic response--as in patients with urticaria provoked by food additives--one of the reasons for diagnostic difficulty is that the offending substances may be present in a wide range of common foods. If the diagnosis is to be firmly established in such cases, it is necessary to show that symptoms remit on an elimination diet and recur after a placebo-controlled challenge.
