Myth Stamped in Red Ink with Rubber Hand Stamp

FACT: Peanuts grow underground and are part of the legume family, which includes green beans, peas, and lentils. However, the majority of individuals allergic to peanut are able to eat other legumes.

In the past, it was thought most people allergic to peanut were also allergic to other legumes, but this is not the case. Lupin, another legume, is an emerging allergen, especially for people with peanut allergy. If you have to avoid peanut, it is important that you talk to your allergist about the safety of eating other legumes, which are not part of your regular diet.
