Even though peanuts have the word “nuts” in their name, they are legumes, not nuts. Allergy to more than one nut is common. 1 out of 2 nut allergic teenagers react to more than one nut. 1 out of 3 peanut-allergic patients also report tree nut allergy. And more than half of nut allergic patients report an allergy to peanuts. People with a peanut allergy also commonly avoid tree nuts because of the likelihood of cross-contact or cross-contamination.
