How Can I Find Information About Allergens In My Food
Elimination diet: Try an elimination diet. You'll remove suspected allergens like wheat or dairy for a week, if symptoms improve, try reintroducing them one at a time in 2-3 day intervals.

I've never had food allergies & tested neg for them, but do have eczema & chronic hives. does this mean i'll react to big allergens like nuts & fish?
Not necessarily: In fact, your own experience with eating nuts and fish is a much more reliable indicator of whether you're actually allergic than the results of skin testing will be.
