Previous studies have confirmed that IgE-mediated, food allergy-induced respiratory tract symptoms occur, typically accompanied by cutaneous or gastrointestinal symptoms. The possibility that respiratory tract symptoms are food allergy induced should be considered in patients who have a current or past history of one or more of the following: atopic dermatitis, wheezing (or experiencing anaphylactic symptoms) after ingesting a particular food or foods, and confirmed food allergy. Moreover, the work-up of food allergy in asthma should be considered in patients in whom asthma is poorly controlled despite persistent use of appropriate asthma medications. A definitive diagnosis of food allergy should be based on clinical history, appropriate laboratory testing, and, when indicated, well-controlled oral food challenges. Treatment is based on establishing a safe elimination diet and an emergency plan for managing reactions caused by accidental ingestion.
