  • Fish oil - more is not better

    Interesting article on the Healthy Skeptic site. Argues that long term, high dose fish oil supplementation isn't a good idea. Kresser has posted other articles arguing that lowering Omega 6 is a far better approach than increasing Omega 3.

    the vast majority of the studies done that have shown a benefit have been short-term, lasting less than one year. The only trial lasting more than four years, the DART 2 trial, showed that fish oil capsules actually increase the risk of heart disease and sudden death.
    Interest in fish oil supplementation started with observations that the Inuit had almost no heart disease. It was assumed their high intake of marine oils produced this benefit. While this may be true, at least in part, what was overlooked is that the Inuit donít consume marine oils in isolation. They eat them as part of a whole-food diet that also includes other nutrients which may help prevent the oxidative damage that otherwise occurs with such a high intake of fragile, n-3 PUFA.

    Should read "high dose fish oil may not be better"

      I was borrowing from the article title, which argues that's more is not better.

        I definitely agree with this. The best solution is limited omega 6, no fish oil pills; just real fish, one serving every or every other day.

            After supplementing with fish oil for over a year, I recently stopped, prefering just to eat fish most days and limit my n-6 intake (no vegetable oils or nuts). Chris Masterjohn's recent article on PUFAs was the main motivator for the change.

            Trouble is that it really isn't possible to measure the effect of such decisions. I guess a conservative approach is warranted when you can't measure the effect. For me that means not supplementing and using diet to minimise n-6 as much as possible and balance it with n-3
            Four years Primal with influences from Jaminet & Shanahan and a focus on being anti-inflammatory. Using Primal to treat CVD and prevent stents from blocking free of drugs.

            Eat creatures nose-to-tail (animal, fowl, fish, crustacea, molluscs), a large variety of vegetables (raw, cooked and fermented, including safe starches), dairy (cheese & yoghurt), occasional fruit, cocoa, turmeric & red wine

              If you really want to know your 3-6 levels, they test for that at www.lef.org

              I had my levels tested, and they came back as 4:1 (4 6s to each 1 3).

                O3 also seems to be more beneficial to women who have already had children and are post menopausal opposed to premenoposal women who havent had children yet and is potentially dangerous if amounts arent monitored...

                  I wonder what the story is if you are menopausal and havent had kids ?
                  and on your last comment.

                    Unfortunately like most things in western society, when something is determined to be beneficial, people immediately assume that more must be 'more' beneficial. However many times this is definitely not the case. Fishoil is the same.

                    Omega3's are essential (as are omega6's!) but having too much, or more accurately, an imbalance, is just as detrimental as not having enough. The correct mindset is to have a balance of omega 6's to omega 3's in the 2-4:1 range. As mentioned, it's best to limit your omega 6's (linoleic and arachidonic acid) and then eat fish or supplement with high DHA fishoil to increase your ratio.

                    It's a fact of biology that PUFA's oxidise. We can limit it, but not halt it completely. Consuming excessive PUFA's doesnt increase oxidation directly, but as there are more PUFA's available to oxidise, much more oxidiation occurs. Oxidation of PUFA's is bad, and leads to cell and DNA damage.

                    Bottom Line, don't go chugging gallons of fishoil. Fix your diet by removing sugars, wheats and grains, and limit your nut and vegetable oil intake, and you will find you won't need much supplementation if any at all.

                      I agree with what everyone else said.

                      The best approach is to eliminate grains, sugar, processed food, and vegetable oils (with the exception of EVOO) and limit chicken (if not pastured), pork (even pastured pork has bad omega 6:3 ratios) and nuts consumption, and stick to (grass-fed or at least hormone/antibiotic free) (lean/fatty) beef/lamb (which has very low omega 6 to begin with) and fish (canned salmon/sardines/tuna and/or wild caught salmon, etc). If one follows this approach, one will not need that much fish oil supplementation. And if one buy 100% organic/pastured meats, fish oil supplementation is probably not needed.

                        Absolutely. PUFAS are just not so stable. It's best to get fat from the more stable sat fats.

                        However, most of us will still be getting more Ω6 than Ω3 and we're still better off balancing that Ω6 with an enough Ω3 to bring the ratios to 1:1...rather than not doing that. Though yes, it's optimal to instead *reduce* Ω6 down to minimal levels.

                            Concerning omega 6:3 ratio,

                            What about a ratio of 4:1? Is this bad? This my daily omega 6:3 ratio. I know a optimum ratio will be 1:1, but I am sure I read somewhere online that 4:1 is acceptable (sure a heck a lot better that those who are in the SAD!).

                              LOL!

                              His calculator is weird. He doesn't take in account how much omega 6 is currently present in one's diet. Personally, I believe he is working undercover for some fish oil companies (taking that much fish oil will cause one to buy them often, thus increasing fish oil marketing.......lol). Great tactic.......
