The danger, as I see, it is that people dont all have the same ability to evaluate advice for themselves and make an informed judgement about which advice to take.
Anyone with an "Ask ??" CureZOne forum is viewed by many as an expert and is, therefore, likely to be believed. It is, in my view, very dangerous for people with a host of medical conditions to be told the answer to their problems is to eat a mono diet; that water kills etc etc.
