Does peanut allergy mean sensitivity to all legumes?
My two-year-old cousin has had an allergic reaction to peanuts. I am unsure if he is allergic to all related peanut family members. How do I find out what he can and can not have?
Although it can happen, it is unusual that a person allergic to one member of a particular family of foods is allergic to all of them. Peanuts are a member of the legume family. Most people who are allergic to peanuts can still eat other legumes with no problem.
The only real way to find out if your cousin is allergic to other legumes is to challenge him with them and to look for an allergic response. If his allergy to these to foods is severe, than you should only challenge with other foods in the same family under the supervision of a doctor.
