Are You Poisoning Yourself with Mercury in Fish?

(NaturalNews) In an attempt to gauge just how dangerous the mercury in fish is, writer David Ewing Duncan decided to measure his blood levels of the toxic metal both before and after gorging on various types of fish.

Mercury is a naturally occurring metal, but one that is highly toxic to the nervous systems of vertebrates, including humans. Studies have shown that it can cause damage to brain functioning, including memory, learning and behavior, and that it can also harm the heart and immune system. The developing nervous systems of children and fetuses are particularly susceptible to its effects.
