What kinds of foods cause food allergies? Of the 12 million Americans who have food allergies, the CDC says 90 percent are allergic to at least one of the following foods:
  • Cow's milk
  • Eggs
  • Peanuts
  • Tree nuts (such as walnuts, pecans, almonds and cashews)
  • Fish
  • Shellfish
  • Soybeans
  • Wheat
That leaves a significant minority of people who are allergic to something else. Some of the other foods that cause allergic reactions include strawberries, blueberries, pears, celery, tomatoes, rice and some seeds.

The best way to figure out whether you have a food allergy is to consult with an allergist. One of the tools an allergist has is a skin-prick test, in which several tiny drops of various allergens are placed on your skin. If any of them produce a raised bump, you are allergic to the substance.
