Dr. Gellner: Keep a diary of symptoms and recently eaten foods. Usually, this is best when you're introducing new foods in their first year or two of life. Some food allergies can be determined by a blood test but others cannot.

Interviewer: All right, so how else can an allergist help?

Dr. Gellner: They can do what's called a food challenge, and that's where in the office the allergist will actually watch your child eat the food that they're allergic to and monitor for a reaction. It has to be done in an allergist's office, because of the concern for severe life threatening reaction.

Interviewer: And how are they treated then?

Dr. Gellner: Avoidance. Unfortunately, there are no allergy shots or medications that can prevent you from having an allergic reaction to a particular food.
