I know we are dealing with parts per million when discussing mercury levels in tuna. I also know that very few cases of mercury poisoning are related to fish consumption, and those few cases are mostly the result of fad diets consisting of only fish for a long period of time. I eat 1 sometimes 2 cans a day. Anyone here been eating that much tuna for a long period of time? (longer than 2 years). If so, do you ever consider getting blood work done? Or, am I getting caught up in the bullsh1t and should stop taking everything I read seriously. Thanks
