Eat your salmon and flax, but watch the pills

omega3_158738637_THINKSTOCK.jpgWhen it comes to omega-3 fatty acid, the dose may make the poison, say researchers at Oregon State University.

“Overall, we support the dietary recommendations from the American Heart Association to eat fish, particularly fatty fish like salmon, mackerel, lake trout or sardines, at least two times a week, and for those at risk of coronary artery disease to talk to their doctor about supplements,” OSU associate professor, Norman Hord said in a release.

Flaxseed, either consumed directly or as a feed supplement for meat and eggs, is also a source of omega-3s.

Studies have shown that omega-3s are associated with lower risk of cardiovascular disease. However, the OSU researchers say that excess consumption of omega-3 supplements on top of dietary sources can lead to inflammation such as colitis and reduced immune response.

They say an increasing amount of products, such as eggs, bread, butters, oils and orange juice, are being “fortified” with omega-3s. Hord said this fortified food, coupled with fish oil supplement use, increases the potential for consuming these high levels.

“We’re not against using fish oil supplements appropriately, but there is a potential for risk,” Hord said. “As is all true with any nutrient, taking too much can have negative effects. We need to establish clear biomarkers through clinical trials.”
