"A large U.S. Centers for Disease Control study (Nhanes III Screenings) found that those with more amalgam fillings have significantly more chronic health problems...."
...and probably more cavities (another chronic health problem)........which led to more fillings. Come'on you guys know better than that.
This is an excellent example of how association does not equal causality. It would be more helpful to know if the percentage of people with these chronic diseases with non-amalgam fillings is any different. This is called a control group.
