I'LL JUST SWITCH TO FISH MCMLXXVII

Once again, there's "new evidence linking high fish consumption to potentially unsafe levels of mercury" - this from scientists at the University of North Carolina at Asheville who tested hair samples from 1,449 people nationwide. The more store-bought fish, locally caught fish and canned tuna a person consumes, the higher his or her hair mercury level tends to be, according to the study.

No real surprises here, except perhaps in what now constitutes a "heavy fish consumer": "The study found nearly 50 percent of the people who described themselves as heavy fish consumers exceeded that [dangerous mercury] level. Heavy fish consumers were defined in the study as people who eat five or more servings of fish a month." So in case you weren't aware, if you eat more than one serving of fish a week, you're a heavy fish consumer, with a 50-50 chance that you're packing the mercury to toxic levels.
