Pretty straightforward: I stopped taking fish oil for Omega 3's and brain health, as I was eating alot of sashimi at the time. I've been reconsidering my stance, as I do eat quite a bit of bacon and chicken broth (with fat), so might need to realign my 6:3 ratio a bit.
I've been considering Fermented Cod Liver Oil and Butter Oil as a supplement, but have to say that this Ray Peat article really scared me away from fish oil:
So...Who is still taking fish oil supplements? Why? Have you read this article, or anything else that has dissuaded/persuaded you to continue/discontinue its use?
EDIT: Does the fermentation of cod liver oil increase it's resistance to oxidation, i.e. make it a safer choice?
I'm more concerned with this: http://paleohacks.com/questions/66467/do-fish-oil-megadoses-increase-the-risk-of-heart-disease#axzz1hmljLzpR than cancer, but I agree that only the absolute sloppiest diets would require them. A single pastured yolk (or 1 battery egg + 1 omega 3 egg) per day supplies DHA/AA in sufficient quantities to restore the membrane fluidity of nascent erythrocytes for a person eating a shit diet, so for us even that may be unnecessary, but obviously it's better to be safe and do at least that much (especially given how nutritious they are in other ways). As far as I know, most here are eating plenty of yolks.
The EFAs are required in miniscule quantities and most of us don't have very much evolutionary exposure to EPA at all. At the very least, I'd try to find a supplement that only contains DHA and try to take no more than 1 recommended dose per day.
On the other hand, it's difficult to argue with results, and many perceive noticeable benefits for various conditions as a result of consumption and many long-lived populations consume these fatty acids in fairly significant quantities. Difficult to say if they thrive in spite of that fact or because of it, however.
What I think is insane is trying to push ω-6 fats out with more ω-3 fats. Overall PUFAs need to be kept low for proper membrane synthesis. Deficiencies are bad; surpluses are bad.
I take 1.2 grams/day. I've read the article.
Heck, I don't know. Right about the time I started taking them, my HDL soared and my triglycerides fell big-time. Maybe I'm superstitious, but I'm okay with what I'm doing.
I used to take a lot of fish-oil supplements because of what I had read and what I had been told. A few years ago a guy came and gave a presentation at the IHS clinic where my father worked. He recommended mega-doses of fish-oil to address the issues of diabetes, heart disease, cancer, depression, suicide and mental health issues that plague the Native American population around here.
The hypothesis seemed plausible to me as the current salmon harvest is a mere fraction of the historical levels, perhaps less than a tenth. Some archeological accounts estimate people have been fishing here for possibly the last 9,000 years. It seems plausible that the people who currently live here could have more of a need for supplementation than most.
It's only been very recently that I've completely stopped taking fish oil and I'm making a concerted effort to only eat whole foods to get my necessary nutrients. Even so, catching 2 dozen chinook a year to freeze, smoke and can is a lot for me. And even that would scarcely be enough to give my entire immediate family a single serving per week. Some years I've been lucky to get a half dozen.
I take fish oil supplements, but not for any specific reason other than the numerous sources that say it's good for you. I haven't noticed any specific improvement in anything, though I probably don't pay attention well enough (a constant issue with me! :D).
Edit: That was an interesting article. I don't know enough one way or the other... maybe I should try a four week A>B experiment when I run out of fish oil to see if I notice anything different. If not, maybe I save a few $$$ for some more grass fed beef or fresh Alaskan king salmon! :)
