What Is a Food Allergy?
A food allergy is a medical condition in which exposure to a food triggers a harmful immune response. The immune response, called an allergic reaction, occurs because the immune system attacks proteins in the food that are normally harmless. The proteins that trigger the reaction are called allergens.
The symptoms of an allergic reaction to food can range from mild (itchy mouth, a few hives) to severe (throat tightening, difficulty breathing).
Anaphylaxis is a serious allergic reaction that is sudden in onset and can cause death.
Is There a Cure?
There is no cure for food allergy. Food allergies are managed by avoiding the problem food(s) and learning to recognize and treat reactions symptoms.
Food allergy therapies are under study in clinical trials, but none has been approved yet for general use.
