I am also type O and I agree wholeheartedly with the diet...with some exceptions because of my candida. I did a survey on a yeast forum and most all of them were type O as well...I think it was like 8 out of 10. There is a certain type of protein that is specific to some people that are predisposed to mercury toxicity and I am betting that it has a genetic relationship to our blood types.

"Heavy metals are found in everyday existence and are frequently hard to avoid entirely. Most people can excrete toxic heavy metals from the body successfully. However, some people—especially those who suffer from chronic conditions—cannot excrete them efficiently enough and a build-up occurs. Recent research also reveals that those who cannot excrete heavy metals efficiently appear to be genetically predisposed to this condition. Research has shown that the APO-E 4/3 and 4/4 genotypes are the worst excretors of heavy metals. Those with this version of APO-E protein—abundant in the cerebral spinal fluid surrounding the brain—will have the highest affinity for becoming ill from exposure to neuro-toxic heavy metals, especially mercury when it is present in combination with others."

I keep my fish intake to a minimum and if I do eat it, I only get it from reliable sources and don't eat the big ones like halibut and tuna, I never liked tuna, maybe there was a reason. <img src="/ubbthreads/images/graemlins/smirk.gif" alt="" />
