Do you have a food allergy?

Food allergy is becoming increasingly common, affecting anywhere from 6 to 12% of children and 3 to 4% of adults. Food allergy occurs when an individual makes antibodies against specific food proteins. When the allergenic food is ingested, the antibodies “attack” the food proteins, resulting in symptoms such as hives, swelling, vomiting, difficulty swallowing, trouble breathing, and/or fainting. The most common food allergens include cow’s milk, soy, egg, wheat, peanut, tree nuts, finned fish, and shellfish. Many children do outgrow their food allergies, however some food allergies can be lifelong. Diagnosis involves a detailed history of the reaction, skin testing, and blood testing. Management involves avoidance of the problematic food and emergency treatment of accidental ingestion.
