No wheat or Dairy

[OakLeaf]

Really, a challenge diet is more accurate and more comprehensive than testing anyhow (not to mention it's free). Give it a try. Stay clean of wheat and dairy for at least four days. (To be more accurate, you'd have to eliminate all common allergens - corn and yeast are the other two really difficult ones, then there's also eggs, soy, chocolate, strawberries, peanuts, tree nuts and shellfish - but wheat and dairy is a start.)

Then reintroduce wheat. Eat your accustomed amount of wheat for two days and record your symptoms. If you start getting symptoms, eliminate wheat again for four days. Then reintroduce dairy and do the same. If you find that you felt better without them, there's your answer. The key is to stay clean for at least four days before you start the challenge.

The other thing is that people with run of the mill allergies can usually tolerate trace amounts of the offending substance, unlike people with anaphylactoid allergies and/or celiac. You may be able to simply eliminate products that list wheat or dairy as an ingredient, not worry about whether they're contaminated in processing.

PS have you ever tried any sea vegetables? Ever eaten maki sushi? Miso soup with wakame? Hijiki is popular these days in a lot of restaurants too. You've probably eaten them without knowing it
