Ok, so after reading the PHD book a year ago and after reading Chris Kressers blog, I stopped taking supplementary fish oil.
From what I remember, Paul Jaminet even said that there is no actual study that supports the use of fish oil, only real fish consumption. Is that true? I thought there where many studies in which they used the isolated oils and found health benefits?
On the other hand, guys like Lyle McDonald, Alan Aragon, Martin Berkhan (I'd say they're amongst the most respecatable, no-BS people in the dieting world) are advocating fish oils as staple supplements and they always use studies to support their claims.
Is it true that there are no studies supporting fish oil supplementation? I'm all for reducing PUFA but on the other hand, many folks that deal with injuries and inflammation seem to have very good experiences with high doses of fish oil caps.
Oh, I'm sure that if you did a pubmed search you'd find all sorts of studies "supporting" fish oil. This NIH article uses the words "likely effective" and "possibly effective" for a variety of conditions ... though that's not exactly high praise.
I think the thing with supplements is to generally avoid them if you can get the desired nutrients from food. So, if you're unable (or unwilling) to reduce omega 6 in your diet and/or eat fish to get omega 3s, then by all means take the best fish oil supplement you can.
Keep in mind that while omega 3 is good, oxidized omega 3 is bad ... what are the odds that the pills you're popping are at least partially oxidized? I.e., from sitting on a shelf for however long or from sitting in a hot truck before it got to the store or to you? As an aside, I'm really glad to see that Robb Wolf has gotten off the high-dose bandwagon.
As ever, Beth has a good perspective. The key being in the word supplement I suppose. Most of the recommendations come from the assumption that people don't eat enough fish. If you can afford it as 'insurance' then I doubt there are serious risks, but given a good diet otherwise I'm not sure it'd be a big enough effect to isolate.
