What triggers food allergies?
Food allergies are caused by the immune system’s reaction to certain proteins found in some foods. The immune system treats these proteins as a threat, triggering allergy symptoms. Foods which cause such symptoms are therefore called allergens. Many food allergens are found in:
- Tree nuts
Those with food allergies may also suffer symptoms in response to similar proteins in other foods. This occurs because the immune system recognizes the similarities and treats both proteins, causing both to act as allergy triggers. Such association is called cross-reactivity. In the case of food, it is also sometimes called Oral Allergy Syndrome (OAS).
What are symptoms of food allergy?
Common food allergy symptoms include, but are not limited to:
- Respiratory problems (shortness of breath)
- Tightening of the throat
- Difficulty swallowing
