Are omega-3 products really the good oil?

Consumers buying foods with omega-3 may not be getting the good oil they think they are says Rufus Turner, a lipids scientist with Crop & Food Research. He and colleague, Dr Carlene McLean, have studied commercially available fish oil in New Zealand, that’s been manufactured overseas. They found it contains varying levels of primary and secondary oxidation products
"These oxidised products result in variations in the quality of fish oils and may explain the mixed results in international human clinical trials investigating omega 3 health benefits” Dr McLean said. Recent results from international cellular, animal and human trials indicate that the oxidised products in fish oils may have potential carcinogenic and pro-inflammatory actions. These products have the potential to increase the risk of atherosclerosis and thrombosis and reduce the potential benefits of omega-3 fatty acids..

Gary Moller comments:
While there are undoubted health benefits from consuming fish oil, it is clear that not all fish oils are the same. If the oil is of a poor quality it is possible there will be no health benefits and possible harm. If you are buying fish oil:

• Do not buy product that has been sitting about on a warm, brightly lit shop shelf


• Purchase a known brand that is from a store that you know has high rates of product turnover


• Preferably purchase fish oil that has added vitamin E which stabilises the oil, preventing oxidation and/or


• Take a capsule of natural vitamin E with your fish oil


• Once opened, keep the fish oil capsules sealed tight and stored in a dark cool, dry place and


• Consume the lot in good time, rather than leaving capsules lying about for several weeks

Note: The fish oils that are stocked at www.myotec.co.nz are leading brand New Zealand products. Only small stocks are held and these are turned over quickly. For the industry response to the report above, read this.
