I have no idea if this information is trustworthy, but I've been saying for years that it isn't the wheat, it's the pesticide. This article starts by sounding like it has studies to back it up, and then devolves into a sensationalist, non-scientific load. You'll have to take it with a pinch of salt and judge for yourself. But I thought it was interesting enough to pass on. If any of you know any more about how much of this is true, let me know.
