Lentils are in the: Legume family, which includes chick-peas, peas, peanuts, beans, & soy. Lentil allergy is #4 among spanish children & #5 among those from india. Peanut allergy more common in the us. Several sites noted that lentils must be boiled at least 15 minutes to destroy harmful toxins in their skins.
