Nut allergies are among the most common food allergies, and they include reactions to almonds, walnuts, and pecans. An allergy to peanuts, however, is not technically a nut allergy.
Many of the 1.2% of people in the United States who are allergic to peanuts may mistakenly believe that they have a nut allergy, but peanuts are not actually nuts — they are legumes, similar to black beans and lentils.

In this article, we look at the symptoms, causes, and treatment of nut allergies.
