See details: See an allergist first. Determine the specific allergic triggers and then you can focus of eliminating them.

See allergist: Most chronic hives are not due to food allergies and thus you should find out whether you are indeed allergic to a food (unless you have had a convincing reaction from eating it) before you eliminate it from your diet. The cause is often unknown but the condition is usually treatable. Up to 30% of CU is likely from an autoimmune process

Agreed. An allergist will be helpful. The immune system is very complex, and with chronic hives, there may be other compounds that are "too much", "too little", "too active", or "too inactive"... leading to the release of histamine here and there, causing ongoing hives (without relationship to what foods are present).
