i think you should be very concerned. the only fish i will touch is wild alaska salmon. the best would be the smaller ones, like the silvers and the pinks. the reds and kings would be more contaminated. fresh alaska salmon is expensive. if you can afford it, youre fortunate. even so, it is contaminated, just not as much as the others.

farmed fish may get you away from mercury, but there are other issues and contaminants to be concerned about. as i said before, i think the eat for your Blood Type Diet is a gimmick for the most part. we were all created to eat fruits. that is if you have human blood!
