It does. But, you are missing the fact there there is more mercury now in the waters, and therefore more in the fish.
You sound like a smoker.
In small fish, I agree. However, in large fish, it is entirely different. It is NOT insignificant.
"The advisory comes on the heels of an extensive report issued by the National Academy of Sciences which estimates that each year 60,000 children may be born in the United States with neurological problems as a result of exposure to methylmercury in the womb."
BTW i have eaten thousands of cans of tuna. I have been tested, have had very high levels of mercury, am currently on DMSA therapy, and have all the classic symptoms of mercuty toxicity. But yeah, insignificant.
PLEASE read some. I was looking for, but could not find the FDA fact sheet about large fish, Many types of fish of X number of inches they recomened that you do not even eat a single bite, because of the mercury. I know kingfish was one of them.
1/3 of people die from cancer. Cancer is from toxins. I do not see how people can ignore this. I challenge all you heavy tuna and large game fish eaters to have a mercury test. The results will suprise you.
BTW, I ate about 7-10 cans a week for 3+ years, along with gamefish.
