Medical Forum / General / Nutrition / October 2004Oils - EFA's DHA - what about this mix?
Hello, I would not live long enough to read up and resolve every controversy about EFA's but still would at least like to be in the right ball park and make sure that I am not totally without the right fats. I have read about the benefits of olive oil, and the benefits of DHA, and that flaxseed oil is good and so on and so forth. The debates about these oils seem to be huge and neverending. Anyway, having said that, how far off the mark would I be if I took the following on a daily basis: 1 tablespoon cod liver oil 1 tablespoon flaxseed oil 2 tablespoons olive oil I am interested in the DHA's for brain and cardio reasons and also want to get some of the anti-oxident, mediteranean type diet benefits from olive oil. I would appreciate any helpful comments. Thank you.

Thus flax oil may not be entirely beneficial. Ground flax seed might be better, as it may provide more lignans as well as fiber. Cod liver oil-High long chain polyunsaturated fats may induce increased mitochondrial membrane oxidation, and thus accelerate aging. > Cod liver oil-High long chain polyunsaturated fats may induce > increased mitochondrial membrane oxidation, and thus accelerate aging. But isn't this true of ALL the essential fatty acids (EFA)? They're all polyunsaturated. And for the short chain PUFA, the body is only ~10% efficient at converting the C18 into C20, so you've got to burn 9 molecules of ALA to get the same benefit of 1 molecule of fish-oil EFA. Seems like the lesson is: take as much fish oil as you need to get your omega-3/6 ratio right, then knock it off. And the amount that Winter suggested seemed like a reasonable level. I guess the other lesson is: if you're going to ramp up your EFAs, ramp up your antioxidants, too. Comments?

I would replace some of the cod liver oil with fish oils or with fatty fish. I would also take some flax seeds or walnuts as a source of omega-3 fatty acids instead of flax seed oil. Flax seed contain lignans and fiber as mentioned. And walnuts are a rich source of myricetin. > Seems like the lesson is: take as much fish oil as you need to get > your omega-3/6 ratio right, then knock it off.
