What do you think of this epidemiological study, Hans? In the Seychelles, they found that people eating lots of fish had none of the symptoms of mercury toxicity even though their bodies contained 6x more mercury than Americans. Some even had 20x more mercury than Americans. I have speculated that the tropical fish are probably low in PUFAs and they also add lots of coconut oil to their diet. Maybe the sunlight exposure helps them to stay healthy on such a diet, too.

OTOH, I have heard anecdotal reports from someone in the United States eating an all-raw diet high in fatty fish (sable and salmon). They were eating the whole fish - head, spine, and so forth. They developed symptoms of mercury toxicity very quickly. I blame this on PUFAs in the fish. I don't think these problems would occur if you ate shellfish or lean fish like pollock, cod, and so forth. What do others think?

There are several factors that could be at work. There was also a report a couple of years or so ago about Asians who were "overloaded" with iron, but didn't have the "diseases" Western "experts" expected. I think this is due to these people not having arachidonic acid in their cells, but Mead acid instead. Another thing to consider is whether they have a diet that is higher in antioxidant-rich foods than most Americans.

I guess you are right about the sunlight exposure. Vitamin D manufactured from cholesterol in the skin exposed to sunlight is known to suppress autoimmunity and a host of arachidonic acid related problems.
