Full Answer

Those who have tree nut allergies tend to keep those allergies for a lifetime, according to Food Allergy Research & Education. Less than 10 percent of children with tree nut allergies outgrow them. If a person is allergic to one type of tree nut, he has a much higher chance of also being allergic to other types.

Since tree nuts can sometimes be present in unexpected foods and beverages, it is important for those with allergies to carefully read all labels before consumption, warns Food Allergy Research & Education. In the United States, food manufacturers are required to list specific tree nuts on all packaged foods. Foods that commonly contain Brazil nuts, nut butters, nut pieces or pecans, among many other ingredients, should be avoided. For some people, coconuts are unsafe as well. Many patients who are allergic to tree nuts also avoid peanuts because of the high probability of cross-contamination.

Medical professionals recommend that tree allergy sufferers keep an epinephrine auto-injector with them at all times. If an allergic reaction begins, the injector is used to slow down the process of anaphylaxis, explains Food Allergy Research & Education.
