What is a peanut allergy?

Written by: AllergySense

Peanuts are a member of the legume family; they are in the same family as peas, beans and lentils. A minority of people are allergic to other legumes.  Although uncommon, individuals may react to peas, lentils, soy and chickpeas. Legumes are not considered tree nuts. Although some children may outgrow their food allergies, it is not very common to outgrow peanut allergies. The majority of children react to their first exposure to peanuts. It is unclear why and it is also unclear as to why there is such a steep increase in the rate of peanut allergies. Children with skin conditions such as eczema are more likely to develop allergies to peanuts.

The peanut allergen structure is also similar the allergen structure of tree nuts, and as a result, children diagnosed with peanut allergies may also be allergic to tree nuts.  Peanuts have also been known to cross-react with peas and other legumes; however, also developing an allergy to peas is less common.  Most people with peanut allergies are able to tolerate soy.  However, it is always safest to check with your allergist first with questions about your specific situation.
