It's nice to hear some (relatively) good news about seafood. From CBS:

Eating seafood twice a week is good for your heart and generally outweighs the risk of exposure to mercury and other dangerous contaminants, the Institute of Medicine said Tuesday. Even so, the government needs to help consumers figure out which seafood is safer, an Institute report said. 'The confusion may have scared people out of eating something that is beneficial for them and maybe for their offspring,' said Jose Ordovas, a Tufts University researcher and member of the report committee. 'Our goal was to put both things in perspective and see where is the balance.'
