The immune system of the body keeps you healthy by fighting off infections and other hazards to our health. A food allergy reaction occur when your immune system overreacts to a food or a substance in a food, identifying it as a danger and triggering a protective response. Symptoms of a food allergy can range from mild to severe. Just because an initial reaction causes few problems doesn’t mean that all reactions will be similar; a food that triggered only mild symptoms on one occasion may cause more severe symptoms at another time.
