Tuna Calculator Calculates Mercury
How Much Tuna Is Too Much?
With all the mercury scares going around these days, are you curious how much tuna is too much? I am. 
The Environmental Working Group has created a tuna calculator that uses the FDA's guidelines for what constitutes a safe dose of mercury. It will calculate the maximum amount of canned tuna that you can safely eat each week and not exceed what the FDA considers a safe exposure level. All you have to do is enter your weight and the calculator does the rest. Pretty cool, especially if you eat a good amount of tuna.
How many cans per week are safe for you?
