Mercury effect on energy: Mercury binds to nitrogen and sulfur in proteins, oxygen from the lungs, sulfur from the liver's detoxification systems, and selenium from the colon. Lower levels of body tissue oxygen due to mercury's binding it may lead to:
Fatigue caused by low blood Sugar secondary to low blood oxygen parasite infestation by setting up an anaerobic (less oxygen) environment, and by lowering the level of the good bacteria which fight off parasites
An anaerobic environment also favors the development of yeast infections and cancer, since yeast is a fermenting spore and cancer is a fermenting cell rather than a normal respiratory (oxygen using) cell.
