IgE-mediated food hypersensitivity accounts for a variety of allergic symptoms such as anaphylaxis, cutaneous manifestations (urticaria, dermatitis, angioedema, upper and lower airway diseases) rhinitis, asthma, and laryngeal edema. IgE-mediated food allergies show rapid onset, whereas non–IgE-mediated reactions take hours to produce symptoms. Worldwide, 6% to 8% of children show allergy to foods in the first 3 years of life, whereas 6% to 16% experience food-induced wheezing. Though a definite statistic of food allergy in adults is lacking, the surveys carried out in the United Kingdom, France, the United States, and the Netherlands suggest a prevalence of adverse reactions to food of 1.5% to 3.8% in adults. This paper gives information about how to diagnose food allergy by different methods. Food allergy is the abnormal or exaggerated immunologic response to specific food allergens. IgE-mediated food allergies show rapid onset, whereas a non–IgE-mediated reaction takes hours to produce symptoms. This paper provides an overview of recent understanding of food allergy in bronchial asthma. It gives information about how to diagnose food allergy in bronchial asthma patients. It involves history taking, immunological tests, oral food challenge testing, and double-blind placebo food challenge testing. © 2005 Lippincott Williams & Wilkins, Inc.
