Tyler there is conflicting information out there for everything, mercury is no exception. But you have to take a stance on it, and mine is that the less mercury I ingest the better off I will be. I respect your opinion, but I am not going to take my chances with eating swordfish sorry. I can provide several articles, forums, and youtube videos on dangers of mercury including from fish. Fish is the second highest source of exposure after amalgam. Most women in Asia don't eat fish when they're pregnant due to mercury in fish. Besides, I've read people store up on mercury in their bodies with horrendous results by following the raw guru AV. It's all out there on yahoo RAF groups.
This is all unnecessary scaremongering. As for mention of articles/youtube videos, I should add that sheer quantity is no sign of quality whatsoever. There is only 1 study, of any remote validity, which can reasonably claim that mercury in such tiny doses from fish can be harmful, and that is the Faroes study. Even that study has long been debunked by the far more rigorous, longer-lasting Seychelles study, and even the silly Faroes study only made a claim for a -0.25 IQ point drop as a result of mercury-consumption(which was, for obvious reasons, dismissed by experts as -0.25 is such a small, non-significant deviation that it
could easily have come up as a result of any randomised trial, meaning exactly nothing.)
As for PDers, amusingly, I've made a number of remarks over the years on how many
Primal Dieters have routinely dismissed genuine health-problems(such as allergies towards raw dairy) as being supposedly "detoxes" or due to some other nonexistent
cause such as heavy-metal poisoning. Indeed, I remember listening to Aajonus on his tapes and being highly amused at how in almost every single consultation, he claimed that they each had heavy-metal poisoning. The odds against such an occurrence being somewhat overly high to put it mildly.
Plus, judging from some articles, Japanese , Asian Americans etc. eat far more fish than other Westerners, so they seem to be happily ignoring the above anti-mercury advice.
Whatever the case, while AV does give credit to the whole mercury-in-fish guff, he does at least claim that raw fish somehow mythically "binds" with the mercury making it supposedly harmless(about as likely as the notion that mercury in fish is harmful), so at least he's not warning his PDers away from raw seafood, which is , after all, a huge food-group within the RPD diet.
