In my experience that is pretty typical of people in the alternative health business - they can actually be even more arrogant than doctors. What really annoys me is that they have a 'one size fits all' approach and take no notice of what one says to them. It's almost as if the value of eating raw vegetables, for example, is a religious belief to them, so mere facts can never change their mind about it and if you disagree you are practically a heretic.
Okay, I know I have probably insulted a lot of people by saying that. Of course I am NOT referring to anyone who posts on this board, as everyone here really knows what it is like to have IBS and, just as important, knows the value of compassion and respect. And there are some NHPs who know this too - the honest ones are actually willing to admit it when they don't know what to do, but there are far too many who just think they know everything.
Rant over. Hope I haven't given anyone indigestion!
