Mercury and fish oil

[Johnka]

According to Lonnie Lowery's new article, fish oil capsules may be a safe way to get your EFA's without the mercury risk:

Fish oil (EPA and DHA)
Pollution affects fish (oil) quality. Polychlorinated biphenyls (PCBs) contaminate various species of fish and affect cognitive function in both children and adults (McCook, 2001). The risk of heavy metal (e.g. mercury) contamination is real with regards to fish consumption, particularly larger predatory fish like swordfish, which consume smaller fish, accumulating toxins in their flesh (Mendez, et al., 2001). The controversy over whether ingested mercury negates the benefits of accompanying fish fats for humans is not settled, however (Guallar, E., et al., 2002; Yoshizawa, K., et al., 2002). In either case, dietary supplements may be a way to avoid the effects of such pollution. Over recent decades, a number of investigations screening fish oil products have resulted in negligible or absent mercury contamination (Bugdahl, 1975; ConsumerLab, 2001; Foran, et al., 2003; Koller, et al., 1989). At least one review has revealed a lack of "key ingredient" in fish oil products, however (ConsumerLab, 2001). A comprehensive screening of all available fish oil supplements for mercury contamination or even EPA and DHA content is not likely, however. Hence risks remain.
