My dietician, who specializes in GI problems actually highly recommeded eating yogurt....specifically Stonyfield or Activia. She said there is no proof dairy is bad for everyone with IBS if you don't test positive for lactose intolerance.
Not that this answers your question. And not that I have been daring enough to try it.
