I think that the Marshall Protocol is worth looking at. From a quick look, it seems that they are saying that you should avoid VitD and sunshine for the duration of the treatment, not that it is bad for you normally.

They will not be right about everything, no-one is, and I accept mercury being a major factor in chronic ill health, but there may be something in the bacteria thing I think so I am having a good look into this. It does not have to be either or, it could be both in the majority of cases. One thing that I have been thinking of, is the condition of my two sons when they were babies. They were in good condition at birth and thrived then after a few months stopped gaining weight as well etc. They must have had mercury from me in utero, but they got worse later which would fit in with the bacteria theory better as it says ont he site that they can have the problem pased on and/or aquire it later.

I don't think that anythihng is worth discounting until one understands the theory properly Bex.
