How can food allergies to wheat, and peanuts effect me?

Rash or stomach ache: Any true food allergy can cause a range of symptoms..An itchy rash is probably most common..But some people get nausea, diarrhea or if severe, even breathing problems. See an allergist to be tested, so you can verify your symptoms are an allergy(ie. Not an intolerance or other problem) and to help determine how severe an allergy you have.

Wide range: Food allergies to foods such as peanut are potential life threatening. Foods such as wheat don't usually cause severe reactions but can lead to worsening eczema, stomach and GI disturbance as well as other annoying symptoms.
