Seafood Consumption Guide Calculator?
Not exactly sure how I ended up on this site, I was reading something about canned tuna, but anyway the article and the calculator might be useful to other people. I'll leave this here so I don't forget as well.
By the way I am a big fan of eating canned tuna, I ate a lot when I was a kid. I was oblivious to the effects and the amounts of mercury canned tuna had though. This changes things.
