Peanut

What is a Peanut Allergy?
Peanuts are legumes and are botanically related to other legumes such as soy, lentils, fresh and dried peas and beans, licorice and carob. To be safe, most experts recommend that peanut-allergic patients also avoid tree-nuts such as walnuts, Brazil nuts, hazelnuts, etc.

Peanut allergy is caused by an immune reaction against the proteins in peanuts. Peanut allergy results when antibodies against peanut allergens are produced by the immune system. The combination of the allergen and antibody produces a series of reactions and symptoms typical to an allergic reaction.

Symptoms
The most common symptoms of peanut allergy include hives, tissue swelling, wheezing, asthma, vomiting, runny nose, itching, nausea, eye irritation.

Treatment
Reactivity to peanuts is usually a life-long allergy. Peanuts can cause a fatal allergic reaction, so your doctor may advise you to avoid any products containing nuts.  Keep in mind that prepared foods and restaurant foods can be contaminated with peanuts or peanut oil during cooking and handling.

A totally peanut-free diet is necessary if there is a known or suspected allergy to peanut.  It is essential that a totally peanut-free diet be followed indefinitely if a person has been diagnosed as anaphylactic to peanuts.  All products containing or having components of peanuts must be avoided.
