📖What is Food Allergy?
Food Allergy is an abnormal immune response that occurs when the body mistakenly identifies a specific food protein as harmful, triggering the release of chemicals like histamine that cause allergic symptoms. Reactions can range from mild, such as hives or stomach upset, to severe and life-threatening, such as anaphylaxis, and typically occur within minutes to a couple of hours after consuming the trigger food. Common culprits include peanuts, tree nuts, milk, eggs, shellfish, wheat, and soy, though any food can potentially trigger an allergic reaction. Unlike food intolerance, food allergies involve the immune system and can be life-threatening even from trace exposure.
