So I've been eating vaguely paleo for about 6 months, and have lost some weight. I read Why We Get Fat, which led me to The Paleo Solution which led me to Primal Blueprint. I'm trying to take this all a little more seriously, and I'm about halfway through the Primal Blueprint.

Here's my question. At several points in the book it's said that we shouldn't be eating Asian caught fish with little follow-up as to why. Is this about the pollution or the carbon foot print do you suppose? Because, well, I live in Asia, and they don't do organic / hormone free/ etc etc the way health obsessed America does. So it's eat what's available or starve. But if Asian fish are particularly polluted, I'll shy away from them. If it's the carbon foot print, then I'll eat up, because there isn't much of one in my case.

Thanks in advance for any advice. ^_^
