With due respect, it really is the same old stuff....improve your diet, take supplements, try alternative treatments. All good stuff. What these guys fail to realise is that really sick people with bad guts have trouble in these areas as a result of the illness, not as a cause of the illness!
I was a martial arts, Yoga and T'ai Chi instructor, vegetarian, etc. before getting horribly ill so I know none of this is the main factor, at least in my case. No offence, but I think this basic stuff actually distracts people from finding the real cause.
