Diarrhea, asthma, arthritis--What is your wheat re-exposure syndrome? 30. January 2011 William Davis (52) Have you experienced a wheat re-exposure syndrome?

Others experience asthma, sinus congestion and infections, mental "fogginess" and difficulty concentrating, or joint pains and/or overt swelling. Still others say there is no such thing. Let's take a poll and find out what readers say.
