What is food allergy?

Food allergies occur when your immune system overreacts to specific proteins in certain foods. This response can cause anaphylaxis when it is severe, which can result in death if not immediately treated with adrenaline. Food allergies are often confused with food intolerance, such as lactose intolerance.
