Scientists Clone Sheep With 'Good' Fat 233

Posted by Soulskill from the pulling-the-wool-over-your-stomach's-eyes dept.
redletterdave writes "Chinese scientists have cloned a genetically modified sheep containing a 'good' type of fat found naturally in nuts, seeds, fish and leafy greens that helps reduce the risk of heart attacks and cardiovascular disease. The gene, which is linked to the production of polyunsaturated fatty acids, was inserted into a donor cell taken from the ear of a Chinese Merino sheep. The cell was then inserted into an unfertilized egg and implanted into the womb of a surrogate sheep. With any luck, this process could be replicated in the future to clone more animals for safe and healthy consumption."

        We also have a very high percentage of our diets consist of processed GMO grains (corn, wheat). If you're having 2 hamburgers with a handful of corn chips and two white wheat buns, the meat isn't going to be the primary component of the meal.

        It seems that every couple months there's a news article about some old guy or gal who died after a fairly insignificant (not particularly active or sedentary, nothing really marked to note) life who spent their entire life having pork (ham/bacon) and eggs for breakfast every day. It wasn't until the inclusion of excess grains that Americans started to have issues in the late 1800s.

      FWIW, the main advance with this announcement is not the omega-3/FAT-1 transgenic aspect, it is the new cloning technique BGI calls handmade cloning which apparently allows lower-tech facilities and higher transgenic clone yield. BGI has already done this transgenic modification with pigs and now they have done it with sheep. With this new cloning technique, however, it might be possible to do this at an industrial scale.

      However, If you are interested instead about this specific "fat-1" transgenic idea, it was done with mice [nih.gov] way back in 2004.

      Although that is possibly true that saturated fats aren't corrolated with increased risk of CHD or CVD, omega-3 fatty acids are required for controlling blood clotting and building cell membranes in the brain and are assumed to be a necessary nutrient. The "healthy populations" you seem to be alluding to likley maintain their consumption of omega-3 fatty acids from seafood and nuts and oils for 6-9 months of the year.

As far as meat, if it didn't eat what it was supposed to eat; pasture raised and organic at that, I avoid it. Chickens eat bugs and grass, not feed. They like to scratch around in dirt, not hang out idly in cages all day. Same with Beef, less the bugs. We're likely evolved to eat a paleolithic era type diet. Going to stick as close to that as possible. You aren't just what you eat, you're also what your food ate.

    What it sounds like they're doing is they've figured out how to genetically modify animals to produce omega 3 and similar types of fats instead of the fats commonly found in grain fed or industrially raised meats. That's actually fairly big (good) news, I think.

    On the other hand, 'healthy' fat can be found in animals which are 'free range'. It's less environmentally intensive. The unhealthy fat found in animal meat is only unhealthy because of the way they're raised.

    • Actually what it sounds like is they are referring to are polyunsaturated fats since Omega 3 is hardly found in seeds. Generally are lower to non-existent in farmed meat and much higher in seeds and grains, and very concentrated in some seafoods. Polyunsaturated fats include Omega 3, 6, and 9. 6 is an inflamation promoting PUFA that is eaten in far too higher proportion in the western diet.
