I generally agree with what you are saying. And MH is not the only person at curezone taking that general approach to healing. I myself basically recovered my health even though i have not removed my 3 amalgams, one large. I followed Andreas Moritz 's advice (he has a forum here too).
He emphasizes diet, lifestyle and cleansing... which worked great for me. for metals he recommends the same, with the addition of a few baths in pescalite clay after the liver is flushed clean.
