Unless I'm missing something all they've done is show that a small group of IBS sufferers who were able to control their sypmtoms on a gluten free diet reacted badly when fed gluten. They found no evidence of intestinal inflammation, damage or latent celiac disease that might explain their symptoms though so this study doesn't really tell us anything about how gluten may affect the general population.

My wife just realized this for herself.
