An experiment with N of 37 isn't going to prove anything.

The researchers conclusions are far different than yours. "Biesiekierski recognizes that gluten may very well be the stomach irritant we’ve been looking for...Currently, Biesiekierski is focused on maintaining an open mind and refining her experimental methods to determine whether or not non-celiac gluten sensitivity truly exists."

You should stop making statements of fact that you have little information about. No one in the medical profession would make a statement such as you did based on that little article. I hope you realize that there are a hundred of other researches doing the same and publishing articles about it.
