Omega-3 fatty acids, which are important components of
many healthy foods, such as seafood, nuts, legumes and
leafy green vegetables, act to reduce inflammation
Score another point for fish oil supplementation, on top of the already enormous pile of scientific research showing it to be a miracle chemical (and I definitely don't say that lightly) [2]. Seriously, if you aren't getting enough omega 3 fatty acids, either from regularly eating lots of fatty fish or through supplementation, you're seriously missing out on some good stuff. Among supplement enthusiasts, it's consistently declared to be one of the only supplements that's actually useful. I prefer the liquid form [1].

- derefr 13y agoIt's not that fish oil is an unalloyed good, mind; just that we get way too much Omega-6 in western diets, and it seems that Omega-3 "cancels it out." In cultures with balanced Omega-3/6 intake, like Japan, fish oil has no benefit.
- brational 13y agoCorrect. The alternative to pounding fish oil supplements is simply stop eating so much refined seed and vegetable oils. A ratio can always be fixed in at least 2 ways obviously.
- teach 13y agoIt's harder than that. Our food supply has changed; sixty years ago when cows ate grasses, beef naturally had some omega-3s in it. Now that their diet is largely corn, beef brings virtually all omega-6s. Ditto for "shelf-stable" foods. Omega-3 fatty acids go rancid at room temperature, so many packaged products have had the omega-3-based fats removed so they'll last longer on the shelves. Source: my wife, who has a PhD in nutrition.
- tptacek 13y agoMy understanding (from investigating this a couple years ago) is that grass-fed beef, while higher in O3's than corn-fed beef, is not a particularly significant source of dietary O3.
- irishjohnnie 13y agoCheck out http://www.ncbi.nlm.nih.gov/pubmed/16500874 http://www.ncbi.nlm.nih.gov/pubmed/16500874
- teach 13y agoI think that is accurate. I only meant to use beef as an example of how our food supply has changed, not to suggest that beef is any sort of good source for omega 3s.
- kdragon 13y agoCorrect me if I'm wrong, but it's not just that grass-fed beef is higher in Omega 3, but lower in Omega 6. So it's not just about Omega 3 intake, but the ratio between the two.
- isleyaardvark 13y agoI believe that is the main reason it is labelled as such and more expensive than regular grain fed beef. Same with free range/cage-free eggs.
- kzrdude 13y agoWild Salmon should be a good omega-3 source, while Norwegian grown salmon is probably not.
- mikkom 13y agoHere is a link to small study about this. > The results show a little more of the healthy long-chain marine omega-3 fatty acid forms known as EPA and DHA in farmed salmon than in wild salmon. > [..] > “Indeed, there is a larger amount of omega-6 in farmed salmon. You get nine times as much as when you eat wild salmon,” says Research Fellow Ida-Johanne Jensen at the Norwegian College of Fishery Science. http://sciencenordic.com/farmed-salmon-retains-good-fats http://sciencenordic.com/farmed-salmon-retains-good-fats
- Florin_Andrei 13y agoThere's a certain optimal ratio between the various omegas. You could get too much or too little from any particular kind. It just happens that modern diets have too much omega-6 and not enough omega-3.
- irishjohnnie 13y agoPlus the Japanese diet tastes better than a fish oil gel cap ... speaking of which, does this mean that the incidence of depression in Japan is low?
- gms7777 13y agoWell, according to this article about a recent study: http://www.washingtonpost.com/blogs/worldviews/wp/2013/11/07/a-stunning-map-of-depression-rates-around-the-world/ http://www.washingtonpost.com/blogs/worldviews/wp/2013/11/07... Japan has the lowest rate of diagnosed cases of depression of any country in the world (<2.5%). Of course, there could be other causes for this, and the accuracy of how well the diagnosed rate represents the actual rate is an open question. In particular, in east asian countries thre seems to be a cultural taboo against admitting mental illness and seeking treatment in order to get diagnosed in the first place. The fact that Japan has one of the highest suicide rates of any country in the world is an especially telling statistic that the diagnosed rate may not be telling us everything.
- saraid216 13y agoA healthy diet is really not a remotely sufficient substitute for a healthy social context. One of the reasons there's a link at all is because we often eat with people.
- hcarvalhoalves 13y agoIt may not be that deterministic, as if it's either diet or social context. One thing can feed on the other. It can start as an emotional response, deflagrating an inflammatory process, revealing the nutritional deficiency. Or it can start with a nutritional deficiency, deflagrating an inflammatory process, which the brains reads as depression. This mechanism is already seen regarding stress and magnesium. High stress -> Mg depletion. Low Mg -> Stress symptoms.
- joyeuse6701 13y agoI wonder if we can make the assumption that a suicide must have come from depression. Or at least, I'm not sure if the reasons/depressions experienced in Japan are comparable to other countries. I'd also agree that the admittance of mental illness may be lower than the actual. There are some pretty strange conditions out there, like hikikimori.
- WalterSear 13y agoFWIW, fish oil demand is driving overfishing. http://www.wired.com/science/planetearth/magazine/15-06/st_infoporn http://www.wired.com/science/planetearth/magazine/15-06/st_i... There are environmentally better sources, thought they are, naturally, not as cheap.
- corysama 13y agoIn terms of $/gram of Omega3, flax oil is much, much cheaper than fish oil. http://www.amazon.com/Barleans-Organic-Oils-Lignan-16-Ounce/dp/B002VLZ81M/ref=sr_1_2?s=hpc&ie=UTF8&qid=1393438936&sr=1-2&keywords=flax+seed+oil http://www.amazon.com/Barleans-Organic-Oils-Lignan-16-Ounce/... http://www.barleans.com/images/supplemental/ot-lignan12oz-sup.jpg http://www.barleans.com/images/supplemental/ot-lignan12oz-su... It also has a lot of 6&9. I'm assuming that still moves you towards a good balance. Can someone tell me I'm mistaken?
- baugarten 13y agoflax has a lot of ALA omega 3's, which are less usable than the EPA/DHA in fish oil
- jonahx 13y agoI am not an expert, but I've read in many places that the omega-3 in flax oil is far inferior, to the point of almost being worthless, compared with fish oil. IIRC the problem is that flax contains omega-3 in the form of ALA, in contrast to fish oil, which contains EPA and DHA -- the forms we actually need. The body can convert ALA to EPA and DHA, but the conversion process is extremely inefficient (something like only 5% get converted).
- dllthomas 13y ago"The body can convert ALA to EPA and DHA, but the conversion process is extremely inefficient (something like only 5% get converted." Interesting. I wonder if that would be practical to do synthetically.
- lectrick 13y agoInstead of killing fish, here is my favorite nut mix (BY FAR!), which also happens to be chock full of Omega-3: http://smile.amazon.com/Planters-Nutrition-Omega-3-Ounce-Canister/dp/B003VMZZ04/ref=sr_1_1 http://smile.amazon.com/Planters-Nutrition-Omega-3-Ounce-Can... Cannot recommend enough. A handful for a snack is filling, healthy and not too caloric.
- chrisgd 13y agoI can never stop at just a handful though
- Jtsummers 13y agoI dole things like this out to myself each day when I fix my lunch. If I'm going out for lunch I pack it anyways and usually eat it between 10:00-10:30am, keeps me from overeating at lunch. Otherwise, yeah, they'd last about 5 minutes.
- chrisgd 13y agoSometimes the simplest idea seems like the best solution. Perhaps not having the entire container in my desk drawer (half open) is not the solution.
- zwischenzug 13y agoBit too much sugar there for my liking...
- js2 13y agoSo you might want to do some research on ALA, EPA, and DHA. Our ability to convert ALA to Omega-3 is apparently fairly limited. This link appears to be fairly well researched: http://lpi.oregonstate.edu/infocenter/othernuts/omega3fa/ http://lpi.oregonstate.edu/infocenter/othernuts/omega3fa/
- Mz 13y agoFYI: Ingredients Walnuts, Sweetened Dried Cranberries (Cranberries, Sugar, Sunflower Oil), Candy Coated Dark Chocolate Soynuts (Dark Chocolate {Sugar, Chocolate, Cocoa Butter}, Sugar, Oil Roasted Soybeans {Soybeans, Soybean Oil}, Artificial Color {Includes Caramel Color}, Corn Syrup, Gum Arabic, Confectioner's Glaze {Carnauba Wax, Beeswax}). Without doing serious research on every ingredient listed above, let me suggest that you (or other interested readers) can just buy Walnuts for the same effect, without being exposed to all this other crap, which may be a problem for some people. Walnuts are unusually high in omega 3. I have a lot of dietary issues and I would be unlikely to eat the above (and I usually do not eat Planter's because most of their nut mixes are made with peanut oil, which is highly inflammatory and tends to make me psychotic and suicidal). I cannot take fish oil. I am allergic to shellfish and I break out in hives when I take enough fish oil. So I have long eaten walnuts when I want to bump up my Omega 3 intake. But, for my purposes, a) avoiding problem oils does more for me than trying to specifically counteract them by adding other oils and b) eating less acidly also goes a long way to control my inflammatory condition.
- pygy_ 13y agoIIRC, you need a 1/5 (Omega 3 / Omega 6) ratio, but our usual diet is so poor in the former that we end up deprived. Palm oil, which is everywhere, has Omega 6 aplenty, and (virtually?) no Omega 3. In Europe, it is usually listed as "vegetal oil" in the ingredients lists. When it's not palm, they put the full name.
- nazgulnarsil 13y agopalm oil is only 9% polyunsaturated, as opposed to something like canola which is 20%.
- pygy_ 13y agoI had never heard of canola oil. The ratio is ~1/2, which is pretty good to know.
- aestra 13y ago> I had never heard of canola oil. It is called different things in different places. Canola is actually a specific cultivar of Rapeseed. Canola actually stands for "Canada Oil" and the term probably isn't well known out of North America. http://en.wikipedia.org/wiki/Canola http://en.wikipedia.org/wiki/Canola http://en.wikipedia.org/wiki/Rapeseed http://en.wikipedia.org/wiki/Rapeseed
- gcb0 13y agoSouth America, canola oil is pretty well known
- esemiss 13y agoPlease be aware of the issue of rancidity before taking any fish oil supplements. http://blog.omega3innovations.com/blog/bid/215649/Is-Your-Fish-Oil-Rancid http://blog.omega3innovations.com/blog/bid/215649/Is-Your-Fi...
- TheEzEzz 13y agoThere's an obvious conflict of interest with that link. They discuss the rancidity of fish oil and then pitch their own fish oil product. I've heard rancidity of fish oil discussed before. It seems like a reasonable thing to be concerned with, but I'd like to see an impartial, scientific discussion.
- ericxb 13y agoI like Coromega brand because it can't become rancid. The oil is sealed in an air tight packet until you consume it.
- manmal 13y agoOpen a capsule of each new batch and smell it. Then put the package in the fridge, and keep it there. Problem solved.
- Florin_Andrei 13y agoThe fridge alleviates many such issues. I've had fish oil capsules that were packaged under nitrogen, specifically to reduce degradation before sale. But those are not cheap.
- irishjohnnie 13y agoGrass fed beef is apparently also a good source of Omega-3 http://www.ncbi.nlm.nih.gov/pubmed/16500874 http://www.ncbi.nlm.nih.gov/pubmed/16500874
- neves 13y agoBrazilian meat is grass fed. Which countries more export grass fed meat?
- chad_oliver 13y agoNew Zealand exclusively produces grass-fed beef.
- irishjohnnie 13y agoI don't know about countries exporting grass fed meat, but in the US there is a growing movement for raising grass-fed cattle and pastured chickens (for meat and eggs) usually within 100 miles of major cities, as opposed to grain-fed livestock raised in large factory farms. The Omega 3 to 6 ratios of the resulting meat (and eggs) is better than the grain-fed ones. It seems that a lot of these inflammation problems are not only caused by the diet of the average person but also caused by the diet of the average livestock that we're consuming.

- tasty_freeze 13y agoThere is recent research linking fish oil and prostate cancer, especially more aggressive forms of prostate cancer. http://www.nlm.nih.gov/medlineplus/podcast/transcript090313.html http://www.nlm.nih.gov/medlineplus/podcast/transcript090313....
- Jach 13y agoI was going to link that too if someone else didn't. But since the base rate is already about 150/100,000 per year, and 15% over a lifetime, and the survivability for prostate cancer is high, the increase isn't really that much and the benefits outweigh the risks for me.

- danparsonson 13y agoThe great majority of effects tested and listed in the 'Human Effect Matrix' at [2] are either minor in magnitude or non-existent. That would seem to contradict your statement that Omega-3 is a miracle chemical. Am I reading it wrong?
- dfc 13y agoThis is reads as "minor or nonexistent? Evidence Level Effect Change Magnitude Consensus A Depression Decrease Notable 100%
- danparsonson 13y agoNo, and I didn't say it did. The parent to my original comment claimed that Omega-3 is a "wonder chemical", having many beneficial effects, and cited that website as evidence. I was responding to that claim by pointing out that the website does not in fact appear to back up their position.
- dfc 13y agoThe problem is you expanded OP's claim. For starters OP never used your interpretation of wonder chemical: "cures many ailments". The article was on depression and OP never broadened the "therapeutic horizon." The linked website did not describe the effects of fish oil on depression as "minor in magnitude or non-existent."
- danparsonson 13y agoI think we disagree on the interpretation of > Score another point for fish oil supplementation, on top of the already enormous pile of scientific research showing it to be a miracle chemical (and I definitely don't say that lightly) [2]. I read that as "here is yet another thing that omega-3 treats", rather than "here is yet more evidence that omega-3 treats depression". Especially since it followed a quote from the article about anti-inflammatory properties rather than specifically mentioning depression. Followed by: > Seriously, if you aren't getting enough omega 3 fatty acids, [...], you're seriously missing out on some good stuff. Among supplement enthusiasts, it's consistently declared to be one of the only supplements that's actually useful. Among supplement enthusiasts, not among depression sufferers. But then it can be so easy to misunderstand the written word; perhaps I missed the intent of the original comment.
- DanBC 13y agoThere is good evidence that supplementing fish oil does nothing to prevent death, but that eating fish does. I haven't got cites but it was pretty clear on this BBC Radio Four programme - maybe someone else has got better sources? http://www.bbc.co.uk/programmes/b019dl1b http://www.bbc.co.uk/programmes/b019dl1b (They talk about the dangers of Selenium supplementation in regions with plenty of bioavailable selenium in the soil, especially when combined with Vit E supplementation. These are not heroic doses either.)
- dfc 13y agoWhy do you prefer the liquid form?
- gtani 13y agoI think Andrew Weil's books are a good common sense source on supplements and he recommends fish oils purified to exclude mercury and PCB's. For counterexamples, I've noticed a few people taking quite large dosages of B complex vitamins. Dr. Weil notes that mega doses of B3 and B6 can cause problems including irreversible nerve damage. He also recommends against resveratrol supplements, another trendy thing.

- tomgruner 13y agoAlso hemp hearts - available from some costco stores and most whole foods are an excellent source of omega 3s. They are good in smoothies too.
- Nursie 13y agoFish oil supplementation is, like most other supplementation, really only applauded by the supplement industry. There's no proof any of it does much, which is why here in the UK all supplement advertising has to include disclaimers like "May benefit the elderly or those on a restricted diet"
- shubb 13y agoThere have been some decent clinical trials showing a high does of fish oil (something like 1g a day) improves mood better than placebo in bipolar depresssives. There are some risks to taking really high doses of fish oil every day though - and not just mercury content. Similar trials for just doing plenty of regular excersise such as walking show a better result. Given that excersise is really good for you, it's probably a better option.
