Peanut allergies are very similar to other allergies, in which the body’s immune system responds abnormally to otherwise harmless substances. When the immune system of a person who is allergic to peanut detects peanut protein, antibodies activate an inappropriate immune response. There is currently no cure for peanut allergy. People who are allergic to peanuts must take great care to be vigilant in avoiding all traces of peanut from their diet. In addition, people allergic to peanut often need to wear a Medic-Alert bracelet and, at all times, carry a pre-loaded adrenaline (epinephrine) injection kit with them for use in the event of a severe reaction.
