Allergies

What is Legume Allergy ?

Peanuts, soy beans, peas, lentils are some of the legumes which cause an allergy. The allergy is caused due to the proteins present in the legumes. People with allergy to a particular legume may also be allergic to other legumes. However, it is observed that only 5% of people with peanut allergy are allergic to other legumes.

What causes Legume Allergy?

The immune system mistakenly identifies the proteins present in the legume as harmful and reacts against it. Legumes also share a similar protein structure. Hence, if you are allergic to a particular legume, there are higher chances that you are allergic to other legumes too. An allergic test can be helpful to check if you are allergic to other legumes or not.
