This article was originally written for a paranormal magazine called The Paranormal Journal, it became known as The Underground Files covering ghosts, ufos, cryptozoology, and government conspiracies amongst others. I no longer write for the magazine and it is no longer in existence. Mice fatty acids in your diet Omega-3 is, or are, fatty acids. That’s what scientists say. They’ve inserted a worm gene into mice, yes, to one day make steak and eggs into the healthiest food for your heart. Where’s the yolk in that? Ouch! Mammals can’t convert omega-6 fatty acids into the healthier omega-3 version and even fish can’t do it. So that beats the song, ‘Let’s do it, let’s fall in love.’ I’m not very good with songs, ‘birds do it, bees do it, lah-de-lah-de-de!’ I think you’ve got the point. And I can’t carry a tune either, neither can I convert omega6 into omega-3 and I just love the fatty acids around my heart. Yeah, you’ve got it, once again, omega-3 and omega-6 are fatty acids that can only be obtained through food, both have many health benefits, but omega3 has been shown to reduce significantly the risk of heart attack and stroke. Nutritionists urge a balance of both, but people generally consume more omega-6 because it is found in common foods: cereals, vegetable oils and whole grain bread. But now, researchers at Harvard University have engineered a roundworm gene to covert omega-6 into omega-3 and have successfully transferred it into mice, according to an article in this week’s issue of science journal Nature. Performing this feat of bio-engineering on animals such as cattle, pigs and chickens could lead to meat, eggs and dairy products that are rich in omega-3 fatty acids. The potential for meeting increased demand for omega-3 is huge, says lead researcher Jing Xuan Kang. “This is a safer and more convenient way than relying solely on fish oil,” he says. The Harvard work demonstrates the potential of technology to produce healthier products, says Alison Van Eenennaam, an animal geneticist at the University of California-Davis who in another project has engineered mice to make omega-3 in their milk. “Instead of eating fish, you could eat a hamburger and still have the beneficial effects of eating fish,” she said. It may also be safer. Many fish that contain significant amounts of omega-3 are contaminated with toxins such as mercury and cancer causing polychlorinated biphenyls because of polluted water. These pollutants are eaten by algae, which are eaten by fish, which are eaten by larger fish. The toxins accumulate at each stage, resulting in sometimes higher levels in the fish that people eat. A non-fish source also would be environmentally friendly, as farmed fish are fed meal made from ocean fish as a protein to increase their omega-3 levels. It takes from two to five pounds of ocean fish to produce one pound of farmed fish, leading to over fishing. Now you know why the fish looks at you oddly when it’s on your plate.
