Transcript

Now this was last year, 2009. This year, scientists may have come up with even better biomarkers for fish consumption. Dioxins, PCBs, and mercury. The most important fish consumption biomarkers were dioxins and PCBs, among men, and mercury among women. A tighter correlation than even omega 3 levels. You can tell how much fish people eat by the amount of arsenic and toxic waste circulating in their bloodstream. In fact you can even take a hair off someone’s hairbrush and tell how much fish that person has been eating by the mercury content in their hair. This was a study done on childrens’ hair clippings. Your whole body gets contaminated with the stuff.

Doctor's Note

Please feel free to post any ask-the-doctor type questions here in the comments section and I’d be happy to try to answer them. And be sure to see the prequel video on biomarkers for fish intake. Also, there are 1,686 other subjects covered in the rest of my videos--please feel free to explore them as well!

For some context, please check out my associated blog post, EPA dioxin limit has National Chicken Council worried products could be declared “unfit for consumption”.
