Nut allergy

Nut allergy is a type of food allergy. It is a hypersensitivity to dietary substances from tree nuts causing an overreaction of the immune system which may lead to severe physical symptoms for millions of people^[1]. Nut allergy is slightly different than peanut allergy inasmuch as the type of nuts that cause the allergic reactions are not the same. Peanuts are considered legumes whereas tree nuts are considered dry fruits. The symptoms of peanut allergy and nut allergy are the same, but a person with peanut allergies may not necessarily also be allergic to tree nuts, and vice versa. Some peanut allergies in caucasians are reversible with weight gain^[2].

Nut allergies occur mainly, but not exclusively, in children. They are usually treated with an exclusion diet and vigilant avoidance of foods that may be contaminated with tree nuts or nut particles and/or oils. The most severe nut allergy reaction is called anaphylaxis^[3] and is an emergency situation requiring immediate attention and treatment with epinephrine.
