Im noodling on my computer before lunch, just about ready to head out for some sushi, when I see the headline: such high levels of mercury were found in tuna sushi (even at some of the best NYC restaurants) that just four to eight pieces of the stuff could put me over my mercury limit for the week. And thats bad, because mercurys linked to impaired memory, hair loss, and joint painyum! I eat sushi for lunch nearly every day, and eight pieces is my standard order. Heres the conundrum: Its as fast as pizza or a ham sandwich, but feels so much lighter and healthierbut is it better to have too much mercury, or to gain ten pounds? The yellow tails starting to look better than fat pants .
