At the risk of driving a tired old pun into the ground, there's something fishy about seafood. More specifically, studies examining the consumption of seafood can't seem to decide if fish is really as good for us as we've been led to believe.
Scientists have something of a love-hate relationship with fish.
In the early 1980's, studies of cultures whose diet contains large amounts of fish oils, like the Japanese and Greenland Eskimos, found low rates of coronary artery disease. As a result, sales of seafood and fish-oil capsules boomed. But as fish intake increased, studies specifically designed to measure the benefits of a seafood diet lent some doubt to the earlier conclusions. Harvard researchers gathered data on the dietary habits of 44,895 healthy men and documented the incidents of heart attacks and heart surgeries over a six-year period. They found that the subjects who ate fish up to seven times a week were just as likely to experience heart troubles as those who eat fish just once a month.
