Food allergy. Manifestations, evaluation, and management.
Allergic reactions to food are more common among infants and children but occur in adults as well. Foods that are most often implicated in allergic reactions are eggs, cow's milk, nuts, wheat, soy products, whitefish, and crustacea. Gastrointestinal, respiratory tract, and dermatologic symptoms, as well as systemic anaphylaxis, may develop. In addition to history taking and physical examination, the workup may include skin testing, the radioallergosorbent test, and double-blind oral food challenge. Avoidance of offending antigens is the most important aspect of treatment. If exposure occurs, antihistamines and epinephrine may be needed for treatment of an acute reaction.
