Peanuts

All tree nuts are generally fine. Examples are walnuts, almonds, Brazil nuts, and filberts. However, chestnuts, coconut, and peanuts do not fit into this tree nut category. Chestnuts are mainly starch and so are included in the starchy vegetable group; coconuts are mainly oil and are included in the fats and oils group. Peanuts are not nuts; they are a legume and are included in the previous legume group.

Nuts are often called "tree-nuts" to distinguish them from the peanut, which grows underground and is a legume.

What causes an allergen disease? Pollen? Cat dander? Shellfish? Peanuts? These are some of the answers likely to be given by the average person, yet he or she would be wrong. All of these substances certainly have strong links to allergic reaction. Indeed, allergy counselors would add milk, soy, and wheat to the list. However these cannot be root causes. If so, everyone would suffer from allergen disease. The root problem is not the triggers (pollen, peanuts, etc.), but a failure of the body's defenses, the immune system.
