Food Allergy
Food Allergy Overview
A food allergy is caused by your immune system overreacting, identifying and triggering an allergic response to a food or a substance in a food. When this happens, your immune system treats that food as a threat and responds accordingly.
Almost any food can cause a reaction. However, allergic reactions are primarily seen in a handful of common foods, including egg, fish, milk, nut, soy, and wheat. Knowing which foods trigger your immune system is an important step in managing your symptoms and avoiding reactions.
