Tree Nut Allergy Diet

General guidelines for tree nut allergy

The key to an allergy-free diet is to avoid all foods or products containing the food to which you are allergic. A tree nut allergy is an abnormal response of the body to the proteins found in tree nuts. In order to avoid foods that contain tree nuts, it is important to read food labels.
