Food Allergies: Overview
Food allergies occur when the body’s immune system reacts against a substance in food causing an allergic reaction. Common examples of food allergies include nut allergies (e.g. peanut allergy) and seafood allergies (e.g. shellfish allergy). Not all reactions to food are allergies, but could be an “intolerance” (see food intolerances such as lactose intolerance) or a poisoning (i.e. food poisoning), or other adverse reaction to a food or additive.
