Correction: the health risk he wrote about was PCBs in fish oil. For this reason he advocates flaxseed oil as a source of omega-3. Whether there is any real danger I don’t know.
PCBs and omega-3s climb the food chain, so they’re pretty well correlated. At some point I eyeballed a chart and decided that mercury was negatively correlated with omega-3s. No idea why.
