I've had a few recent debates with people on this subject and figured we could talk about it here.
There are tons of other articles out there; this is just one of them.
I was informed by my brother in law (a chemist) that the EPA is now stepping on the FDAs' turf by telling the people what not to eat (as far as fish go) in order to steer clear of foods with the highest mercury content.
I don't see the actual mercury to be the first issue here. I believe that it's still the fact that our bodies aren't made to process HFCS and that is the reason why we shouldn't eat the dam stuff.
