PREGNANT WOMEN EATING TOO MUCH FISH

That's USA Today's headline. It's no longer an abstract theory: A new EPA study says that 300,000 to 600,000 babies born in 2000 got "unacceptable" levels of methyl mercury from their mothers eating "a diet rich in fish," potentially dooming them to "developmental problems and difficulties with visual and motor integration." The study's author says it emphasizes "the importance of paying attention to the advisories" - you know, the convoluted instructions about which fish you can have more than once a week, or once a month, and which will kill you straight out, etc. yet being sure you eat enough fish to get those fantastical health benefits. I thought veganism was the one where you had to be constantly paying attention to what you ate.
