What are the symptoms of food allergies?
When does a food allergy happen? What are the most common food allergens? Eight foods cause 90 percent of all reactions: milk (dairy), eggs, peanuts, tree nuts, fish, shellfish, wheat and soy. Allergies to peanuts are becoming more common and can be life threatening. Some schools are banning peanut and tree nut products. 4. How are food allergies diagnosed? An allergy doctor, or allergist, can do a skin prick test or a blood test. Keep in mind that these tests do not always show that the person will have an allergic reaction. 5. What safety measures can be taken? Food allergies are more common among children (6 percent of young children have them).
