I'LL JUST SWITCH TO TUNA...

There have been rumblings about mercury in tuna for pregnant women, and now they're turning into full-fledged across-the-board warnings. A new U.S. advisory recommends a limit of 12 ounces of fish and/or shellfish each week. Hmmm. Kinda hard to keep up the Omega-3 intake on that paltry amount. Tuna joins a rogues gallery including some fish - swordfish, king mackerel and tilefish - that should be avoided altogether.
