If you think you have a tree nut allergy track your diet and symptoms. Keep a diary of the foods you are eating and what signs and symptoms you are experiencing after eating those foods.
Remove tree nuts from your diet for 2-3 weeks. Be sure to take out foods that state, “may contain nuts” on the food label. You can use www.foodfacts.com as a guide for ingredients to avoid or for substitutions. After 2-3 weeks gradually reintroduce tree nut products into your diet and see how your body reacts. If your symptoms are relieved during the time the food is eliminated, you may be allergic to that food. See your doctor for proper diagnosis.
Skin Test: See your doctor or an allergist and get tested. Your doctor can perform a skin test. A tiny amount of a food that can possibly cause an allergy is applied to your skin, and then your skin is pricked to allow that amount of food to get below the skin’s surface to see if you have a reaction. If you are allergic a rash may develop or another type of reaction can occur on the area that the food was applied.
Blood Test: A blood test, also called a RAST (radioallergosorbent test) can determine the amount of immunoglobulin E (IgE) antibodies in your blood. Your blood is sent to a lab where they test foods with your blood to see if a particular food causes you have high amounts of IgE. If you have high amounts of IgE then you are allergic to that food.
