What should 2yrs old boy eat if he has eczema?

The other way around: Food allergy has been known to flare up the eczema. I would like to suggest to make a diary of foods he is taking. That way, you would be able to sort out food items causing the eczema worse.

Complex question: It is rather a complex question that you just ask. Traditionally, we advise our patients not to introduce some major highly allergenic foods into an infant diet until he or she reach 2 years old. Those are cow milk, egg, soy, wheat, seafood/shellfish, peanut/tree nuts. Only if eczema is uncontrolled, then food allergy is needed to be evaluated and a trial of taking off that food may warrant.
