Omega 6 and 3 in nuts, oils, meat and fish. Tools to get it right.

(If you would like these omega 3& 6 charts  as a PDF, simply donate via paypal – at right – to get my paleo book sent to you – it also has carbohydrate charts and protein charts, plus 50 pages of other great practical paleo info like this)

You are strict paleo, you eat nothing but meat, seafood, fruit and veggies, nuts and seeds. Your snacks are mainly a handful of almonds. Did you know just 60 grams of almonds gives you all the omega 6 you need – and more may be detrimental?

One of the ways our diets have changed dramatically from the diets of our ancestors and even the very recent past is the ratio of Omega 6 to Omega 3 polyunsaturated fatty acids in the food we eat. A huge amount has been written about this subject, dozens of studies have been published. I’m not going into detail, the object here is to provide tools to help you get this balance right. At the end of the page – I’ve posted some links to other interesting blog posts and articles.

(For a really well explained primer on the fats see this article from Anastasia Fat Glorious Fat: Part 1 and Part II)

What are Omega 6 and omega 3 polyunsaturated fatty acids?

A fatty acid molecule has a chain of carbon atoms linked together with hydrogen atoms attached on one side. In a saturated fatty acid each carbon has a single bond with the neighbouring carbon atom and a single bonds to two hydrogen atoms (Carbon atoms always make 4 bonds). In an unsaturated fatty acid chain one or more carbon atoms is linked to its neighbour with a double bond and only one side hydrogen atom attached. Mono-unsaturated fats have one carbon to carbon double bond, and poly-unsaturated fats, two or more. Here is a triglyceride (the usual form that fats are found – 3 fatty acid chains linked to a glycerol molecule or backbone at one end) that has two saturated and one mono-unsaturated fatty acid chain.

This is Linoleic acid – also known as Omega 6. The reason it is called omega 6 is because the first double bond is at the 6th carbon atom from the Omega end as shown:

Here is a 3D ball representation:

An omega 3 fatty acid therefore has the first double bond at the 3rd carbon. Here is alpha linolenic acid, showing it is 18 carbons long with 3 double bonds:

Even though these are shown as straight lines in the diagram – in reality the double bonds make the fatty acid bend and swivel. This is what makes the unsaturated fat liquid as opposed to solid at room temperature.

Omega 6 and Omega 3 fatty acids are 2 different classes of polyunsaturated fats. They are both important, because they are made into powerful regulatory hormones. Omega 6 fats are primarily converted into a range of pro- inflammatory hormones and omega 3 into anti-inflammatory hormones. Perhaps it would help to think of the analogy of hot and cold taps. Hot being omega 6 and cold being omega 3. We need a balance of hot and cold to get the right temperature. Due to the abundance of omega 6 in our diets from chemically extracted vegetable oils, (see graph below and the recent increase in salad oil, shortening and margarine) and a lack of food sources of omega 3 like cold water fish and grass fed / wild meat we have an imbalance. An ideal ratio is 4:1 up to 1:1 of omega 6 to omega 3. This is a long way from the standard American diet which gives 20:1. Imagine the hot tap (inflammation) on full and the cold tap (anti-inflammation) on a dribble. Inflammation is rampant.

Per capita fat supply USA 1909 – 1999 (Krispin Sullivan)

There are potentially 2 different ways to rectify this. One is to add a high dose of omega 3 to balance the amount of omega 6 we eat. The other is to minimise omega 6 and increase the omega 3 just enough to give an ideal balance. Which is the best solution?

Polyunsaturated fats (PUFAs) are far more unstable than mono-unsaturated and saturated fats because of all the carbon to carbon double bonds. These double bonds are easily oxidised, so PUFAs are more susceptible to oxidation – called lipid peroxidation http://en.wikipedia.org/wiki/Lipid_peroxidation.  This oxidised fat can cause cellular and DNA damage. The more PUFA in a cell membrane the higher the risk of oxidation, and consequent damage. More in this case is not better. Adding large amounts of Omega 3 to balance omega 6 is not the best solution.

So the best way to improve the balance on omega 6 to omega 3 is to reduce omega 6 as much as possible. Of course some omega 6 is essential as it is needed as a building block for eicosanoid hormones. In a normal diet it is virtually impossible to go low enough to cause omega 6 deficiency. When we bring the total amount of omega 6 in our diets down, we can then easily add fish (like salmon and sardines) or fish oil to get the ideal ratio between omega 3 and 6. How low should we go with omega 6? 1 -4% calories is recommended by most Paleo researchers.  In a 2000cal diet this 2.2 – 8.8 grams omega 6 per day. (Edit: 24th July 2012 – I went to an omega 3 symposium recently and the recommendation from Dr Alex Richardson is 2 – 3% calories from omega 6 PUFA. That is just 3 – 5 grams a day. You would easily get that just be eating meat and seafood, let alone adding nuts or oils) Current thoughts are to focus on total amounts consumed each day not the ratio in different foods. Using 3-6 differences in essential fatty acids rather than 3/6 ratios gives useful food balance scores

How to decrease your Omega 6.

Most paleo eaters are aware of the need to decrease omega 6, however my observation is that following the eating guidelines does not automatically mean people reduce omega 6 enough. Look at the CrossFit nutrition outline “…base your diet on garden vegetables, especially greens, lean meats, nuts and seeds, little starch, and no sugar.” What do many eat for snacks? Nuts. Particularly almonds. And many use almond meal as the basis for grain food alternatives like pizza bases. Just 100 grams of almonds – 3 small handfuls gives you a whopping 12 grams of omega 6.

So here’s what I’ve done to help you out. I pulled together some nutrition data from http://nutritiondata.self.com and made up some tables showing you the omega 6 content of oils, nuts and seeds, and meat. Aim to get no more that 6 – 10 grams of omega 6 per day. Omega 6 oils should be replaced by those containing predominantly mono-unsaturated fat like olive, avocado and macadamia nut oil, and saturated fats like coconut oil.

Following that is a table of fish and seafood showing the omega 3 content per 100 grams of fish, make sure you add in enough omega 3 to give you around a 2:1 ratio of Omega 6 to Omega 3. Instead of eating fish you can take fish oil. However I recommend you choose your oil carefully. Oxidation is a problem, I choose fish oil I know has been tested for oxidation, and smells and tastes fresh and clean.

Note: There is a lot of variation in the measurement of omega 6 and 3 content in foods, depending on the food the animal is fed, the food sample measured, variation in fat content between animals etc. I have tried to pick a representative measurement. Think of this as a guideline, it may not be 100% accurate for the food you are about to eat.

Here are the complete charts on a PDF

  1. Wow…those tables look like a lot of work. Thank you.

    I know peanuts are legumes, but lots of folks think of them as nuts. So, from the Nutritiondata.com website, dry-roasted peanuts (100 g) have 15,691 mg of omega-6, and only 3 mg of omega-3. Terrible ratio if you’re trying to move in a paleo direction.

    I’m going to start eating more walnuts. Just wish they had more flavor.

    • The downside of eating walnuts is that they have a lot of omega 6 as well.

      • Kate #

        But because of the ratio (close to 3:1) doesn’t it balance out? If not, what other source of fat would be preferred?

        September 22, 2011 at 4:44 pm Reply
        • The omega 3 found in walnuts is the short chain omega 3 – ALA – it is 18 carbons long. It is poorly converted to the longer chain EPA 20 carbons and DHA 22 carbons long that are the precursors of eicosanoid hormones. Whe looking at choosing any fat it is best to look at the total amount of omega 6 it delivers. It is the total amount eaten during a day that counts, and walnuts deliver a fair bit.
          Choose fats based on the amount of omega 6 in them – i.e pick those with the least.
          To balance the omega 6 choose seafood or meat with the highest omega 3. The omega 3 in seafood is the long chain EPA and DHA.

      If you buy fresh nuts in their shells, keep them in the fridge and crack them when you are ready to eat them, they will taste great.
      All nuts have really really sensitive oils that go rancid immediately upon exposure to sunlight and oxygen.
      The taste difference is phenomenal!

    So you’re saying that a 3-egg breakfast pretty much maxes out the omega 6 for the day?

    May 10, 2011 at 3:45 pm Reply
    • 3 eggs (1 egg weighs approx 50 grams) has approximately 3 grams of Omega 6. 2 teaspoons of butter has approx .2g, bringing your total omega 6 to just over 3 grams. So you can eat more than just the three eggs and butter and you will still be less than 10 g day omega 6.

    anyway. you missed the leafy greens and wildplants and plants in general.

    May 10, 2011 at 5:28 pm Reply
    • Yes I did. Leafy greens – although they do have omega 3, it is short chain ALA as shown in the diagram in the post. It is 18 carbons long. EPA and DHA found in fish oil are 20 and 22 carbons long, only EPA and DHA are in their usable form, i.e. they can be directly converted into eicosanoid hormones. ALA has to be elongated by an enzyme – and in many people it is poorly converted to into the longer chain omega 3. Studies show perhaps 5% is converted. If you took the plants highest in omega 3 – grape leaves. 100 grams contains 856mg of ALA. 5% is converted to EPA/DHA – 100 grams of grape leaves gives you 40mg EPA/DHA. You need minimum 1000mg long chain omega 3 is re day for best health. 2.5 kg of grape leaves is required! That’s a lot.

    • Yes, one column is mg per 100grams and the other is grams per 100 grams – both are omega 6. I put grams amounts in as it is a bit easier to read than mg.

  13. I reiterate the earlier commenter: So my 3 eggs scrambled in about half an ounce or more of butter reaches the 6g of Omega-6 level in just the one meal? How is that healthy when every paleo site you go to advocates eggs and butter? I eat paleo, but I see stuff like this that seems to suggest there are a lot of unanswered questions about Omega-6 and health.

    I appreciate the effort putting this together, not least because all similar charts I’ve seen involving Omega-6 have been overly complex and mainly unhelpful. I would suggest though that for the sake of comprehension you discard the mg numbers and instead classify everything in grams. either that or classify everything in mg but round the numbers so that it’s easier to deal with.

    Also – while 100 grams (btw , although they are scientific I hate damn the damn decimal system) or 4 ounces of protein is a good human-scale amount to use, the same amount is not good for fats. 25g – or about 1 ounce. would be a better reference point. If you made a really good chart, with “portions” or “dosages” that corresponded to what people actually eat you would have paleo folk using that as THE go-to resource for their Omega-6 and 3 reference.

    May 16, 2011 at 3:30 am Reply
    • 3 eggs (1 egg weighs approx 50 grams) has approximately 3 grams of Omega 6. 2 teaspoons of butter has approx .2g, bringing your total omega 6 to just over 3 grams. So you can eat more than just the three eggs and butter and you will still be less than 10 g day omega 6.

      I live in the decimal system, sorry but you guys in USA just don’t fit with the rest of the world!

      I take your point about different portions used for oils and fats, but personally I find when you start getting into portion sizes it all becomes confusing.
      If I have time – I’ll put in another column with a smaller portion for the oils and fats. However most people use small amounts of fat, 10 grams for example is just over 2 teaspoons – so divide the mg per 100grams by 10 and you get the amount of omega 6 in a desert-spoon measure.

      (I do this for love, and have to fit it around work that brings in money)

      May 16, 2011 at 3:58 am Reply
      • No – I understand this is a labor of love, and it is appreciated.

        But it says in the table that 1 egg scrambled has 1916 mg Omega-6. X3=5.75g, not 3g. so where does the figure of 3g come from?

        May 16, 2011 at 1:44 pm Reply
        • 1916 mg per 100grams – which is approximately 2 eggs, 1 egg weighs about 50 grams, so 3 eggs is approx 150 grams, 1916 x 1.5 = approx 3000mg

    Interesting read on the CLA, but I have read numerous studies touting its effect on fat burning and muscle gain when injested. Since the natural ratio of Omega 6’s in nature is much higher than 3’s I have to wonder if we are missing something here.

    What about mercury in fish? If we start to eat a lot of high Omega 3 foods are we not endangering ourselves with heavy metal poisons?

    Just curious as I am not completely on Paleo/raw type diet, but for the most part eat this way.

    i remember here where i grown up in south germany. its easy to get fresh walnuts in autmn. often here is abundance of fresh walnuts. this isnt store bought this isnt raw nuts. its not rancid. its fresh fallen from the tree. and if you have taste them they are different then store bought even raw certificated walnuts. its very fresh and juicy and less sticky to the teeth. other people live in the amazon rainforest andhave abundance of paranuts and some native cashews and native wild pecan or other jungle nuts. Do you think they look at omega 3 6 ration. no they doint. real life is more easy and more complex than science comics or scetch ups. that is why western price in his simple study are so famous cause its simple and real.

    so the best is to look at indegenous or traditional cultures with good health. And then make up an scientific research or science comic. i call it comic cause in a comic you cut different pieces or pictures together. and this is like a scienctific work.

    beside walnut tree is a natural remedie. you can use the leaves by to high sugar in blood and also by stomache problems and other issues if you read different herb books or textes.

    Is it possible to be allergic to omega 3’s. I have an allergic reaction to just about every one of them and my throat closes up after I eat one of them. I notice it is especially bad in the foods with the highest concentration of omega 3’s. Fish, flax, nuts…etc.

    • People are usually allergic to protein rather than fat. It is possible that highly purified fish oil – if it has no protein will not cause an allergic reaction.
      Perhaps you need to get allergy tested to find out exactly what you are allergic to.

    It is interesting to see that farmed atlantic salmon have higher O6 and lower 03 levels than wild caught atlantic salmon. That seems backwards to me.

    November 21, 2011 at 8:36 pm Reply
    • I would expect to see wild salmon with a lower omega 6. The food wild salmon eat would be other sea creatures and that would have omega 3 at high levels. Farmed salmon would eat a diet that contains some grains or other agricultural foods that increase the omega 6 in their diet. This is why wild salmon is a better choice that farmed salmon.

  21. Hi Julianne. Is the data for the eggs based on free-range eggs? I am Australian but live in Singapore and it is difficult to get free-range eggs here unless you pay a bucketload! However I have found some eggs that say they contain omega 3 and according to the nutrition info on the box, they contain 0.2g of EPA & DHA per 100gm (or 0.1g per 52g egg) and 0.3g of Linolenic acid per 100gm (or 0.2g per 52g egg). Is this a good ratio or do other factors effect this? Should I be paying the extra for the free range eggs?

    Also, I eat Paleo, but am very new to it. If we can only get our omega 3 from seafood, will I have to be eating seafood everyday to balance the ratio? I love seafood but eating it everyday can be hard, when my husband is not a big fan. Should I be taking a fish oil supplement? Really considering this option, but have no idea which is the best fish oil supplement to get. Any advice would be greatly appreciated.

    November 22, 2011 at 8:02 am Reply
    • It looks like those eggs have more omega 3 than standard eggs – I believe it is because they get fed more flax seed.
      I don’t think it is possible for people to get enough omega 3 unless they eat seafood or take fish oil. I take fish oil and notice I feel better when I do. I generally recommend about 1000 – 3000mg EPA+ DHA per day (add the EPA and DHA content of the fish oil capsule together)
      I look for omega 3 that has been purified, concentrated and tested for oxidation.

      November 22, 2011 at 8:12 am Reply
      • Wow, thanks so much for the speedy reply! Well, I’ll keep eating these eggs, but I’ll keep my eye out for some cheaper free-range eggs here.

She and Dr. Neil Speight M.D., and John Foster M.D., have helped thousands (their claim) recover from many different chronic conditions using this therapy. Here’s a link:

    • Yes – some people do not get enough long chain omega 6. Supplementing with Evening Primrose oil can be tricky. It is very easy to get too much. The amount required is so individual. If I take it I feel worse not better. I note that they suggest testing – measuring the fatty acids on cell membranes. That would certainly make supplementing more accurate.

    Julianne- Thank you so much for this info. I started a paleo diet 18 months ago, and within 3 weeks started having gallbladder attacks. My gb is full of stones from my lifetime of poor eating, but something about the paleo diet set it off. No one has been able to figure out why. I have gone off and on the diet about 3 times this year, and each time I restart the pains have returned, worse than before. My last round was 1-2 attacks each day for 3 weeks (ugh). I can’t take the pain anymore, and I have reluctantly scheduled surgery in 2 weeks. However, I am certain that this problem is the canary in the coal mine, and I am determined to correct it. I am not eating significantly more fat than before – I had already converted to coconut oil, gluten-free, etc, before going paleo. My feeling is that the omega-3/6 balance may be a part of the problem, and reading your article seems to confirm this. My version of paleo tends to be: chicken, beef, and almonds/almond meal. Very little fish, due to my lack of cooking skill with seafood. So I am thinking that the huge increase in omega-6 may have set off a chain of inflammation that was waiting to occur. If you have a moment, could you comment on whether or not you think this is a possible explanation? Many thanks! – Robyn

    • I’ve heard of a few people who have had this experience – it may be because fat in the diet has been increased and this causes bile to be pushed out to digest it. Gallstone production is linked with high sugar / starch / insulin in the diet. So previous diet could have caused it and higher fat diet trigger release of stones.
      If you are not eating oily fish – do take fish oil, I find it makes a big difference in energy levels and reduced inflammation.
      Here is what one person has written about it:
      “As for gallstones, they occur when bile in the gallbladder becomes over saturated with cholesterol. Naturally, this leads people to wrongly assume that foods which are high in cholesterol and fat should be avoided. In fact, a low-fat diet will actually prevent the gallbladder from emptying, allowing the saturated bile to sit there for a long time and become crystallized, forming gallstones. It is actually the insulin response to the sugars that we eat that causes this super-saturation of the bile. Therefore, a diet that is high in sugar and low in fat is a double whammy of sorts and sets the table beautifully for the development of gallstones. On the other hand, a high-fat diet will result in a gallbladder that will empty on a regular basis and there won’t be any over-saturation of the bile.

      It is important to also know that once gallstones are created, moving to a high-fat diet will cause the gallbladder to empty, with the stones, and this may be quite painful. Whatever you do, don’t misinterpret this pain as being from the high-fat diet. Instead, realize that the pain is from the gallbladder’s elimination of the gallstones that a high-carb diet created in the first place. Sticking to a low-fat diet will keep the pain down, but only temporarily as the gallstones continue to increase in both size and number. It is important that you understand this and make the necessary dietary changes sooner rather than later.”

    Julianne, you mention that you “…look for omega 3 that has been purified, concentrated and tested for oxidation.”

    Can you recommend specific brands of fish oil tablets that meet your screening criteria?

  27. You can ask the manufacurer what process they use for quality control otherwise there is IFOS http://www.ifosprogram.com/IFOS/ConsumerReport.aspx and EPAX http://www.epax.com/Purification_Technology/

    I personally use Zone OmegaRx (IFOS) or Nutralife Omega Science (EPAX) available from me by mail order if you live in NZ http://www.zonediet.co.nz/shop/

    Omega-6 fatty acids lower LDL cholesterol (the “bad” cholesterol) and reduce inflammation, and they are protective against heart disease. So both omega-6 and omega-3 fatty acids are healthy. While there is a theory that omega-3 fatty acids are better for our health than omega-6 fatty acids, this is not supported by the latest evidence. Thus the omega-3 to omega-6 ratio is basically the “good divided by the good,” so it is of no value in evaluating diet quality or predicting disease.

    • There is some debate around the studies that have been used with respect to relacing saturated fat with n-6 PUFA, and reducing CVD risk. Here is an exerpt from one critique:
      “Pedersen et al. state that trials have demonstrated unequivocally that ‘replacing SFA, largely from dairy and meat fats, by PUFA reduces serum cholesterol levels and CHD risk’, referring to a meta-analysis by Mozaffarian
      et al.(5). But Mozaffarian et al. note that their findings cannot distinguish between the potentially distinct benefits of increasing PUFA v. decreasing SFA, and that, given the limitations of each individual trial, the quantitative pooled risk estimate should be interpreted with some caution. Pedersen et al. state that the changes in CHD risk occurring in the trials mentioned were attributable to replacing SFA by PUFA, and that in the Leren trial(6), some trans-fatty acids (TFA) were also replaced by PUFA. Ramsden et al.(7) showed that in the Leren trial, the control group consumed 9·6 g/d of TFA, while in the experimental group TFA were restricted. Ramsden et al. also noted that a pooled analysis of prospective cohort studies showed that each 2 en% replacement of TFA with PUFA reduces CHD risk by 32%(7). In addition, they showed that in all seven trials included in the meta-analysis by Mozaffarian et al.(8), non-hydrogenated study oils were substituted for TFA-containing fats, oils and foods. The mean estimated TFA content of the seven control diets was 3·0 en%. It is not clear why the confounding role of TFA was not
      considered by Pedersen et al.” Hoenselaar, R. (2012). The importance of reducing SFA intake to limit CHD risk. British Journal of Nutrition, 107(3), 450-451.
      Omega 6 reduces both LDL AND HDL.
      We also need to be aware of population studies such – e.g. the Israeli paradox: Yam, D., Eliraz, A., & Berry, E. M. (1996). Diet and disease – The Israeli paradox: Possible dangers of a high omega-6 polyunsaturated fatty acid diet. Israel Journal of Medical Sciences, 32(11), 1134-1143.
      Also some people are sensitive to omega 6: In the Framingham Heart Study, gene variant APOA5*2 showed increased TG and smaller LDL size when PUFA in diet was >6%E
      I think we need to be cautious about hihg levels of dietary omega 6.
      Israeli Jews have a very high intake of omega 6 PUFA in comparison to the USA and other European countries. The authors ask whether this contributes to the high rates of heart disease, hypertension, type 2 diabetes and insulin resistance. N-6 PUFA are highly unsaturated and prone to lipid peroxidation and free radical formation.

    more important than the absolute values, it the ration omega 3/6 that matters; but mind you, too much omega 3 is bad naturally, for instance you’ve got Wound healing problem.

    After reading so much information about fats and oils I can honestly say I am no closer to an answer. For every study there is another one out there that contradicts it. I don’t believe any of you really know what you’re talking about but everyone seems to think they have the answer. I think the best strategy is to stick to as natural a diet as possible, so if it comes from a packet or bottle its probably not something you should eat a lot of.

    • I’ve read a lot of studies – and I agree to an extent – natural fats are best. However the overwhelming evidence points to a need to a certain amount of omega 3 in the diet. Less and you increase your risk of brain and blood vessel issues and inflammation. Excess omega 6 is also well linked to studies, – the amount we need is a little less clear.

    Could you add canned cod livers to your seafood chart? For example, King Oscar Canned Cod Livers in own oil.
    Thank you

    A quick question.

    For eggs, it isn’t very clear about the size. “Egg whole” means one whole, normal size egg right?

    What about egg yolk? What size is it? Any data for egg white?

    January 15, 2013 at 6:22 am Reply
    • I refers to 100 grams of whole egg. Egg whites have no fat in them.
      Egg yolk data would be useful – I’ll look into that, egg yolk is appraximately half the egg, so egg yolks only would double the omega 6

    Hi …I am starting to think that we can over-analyse things where we are losing the bigger picture. Nuts and seeds won’t bugger you up, in fact they have a host of nutritional components (not least magnesium) which are shown to reduce inflammation and prevent the onset of disease.
    As long as our carbs are kept low~ish enough that we are chiefly burning fat then I think we can find healthy balance in our bodies.
    Foods are greater than the sum of their parts I think
    Here is a good paper I came across which may help those wondering about can they eat nuts or not :

    Just wondering about almond flour in relation to Omega 6? As its the most common flour to be using on a Paleo diet, can you overdo it?

    March 7, 2013 at 4:35 pm Reply
    • If you use 100 grams of almond flour – that is the same as using 100 grams of almonds. Yes – it is easy to overdo, and get too much omega 6. I don’t recommend using lots of almond flour.

    Hi, I noticed that most of the charts here list omega 3 ALA, not DHA or EPA. Could it likely be a little misleading?Any other credible sources that provide information on DHA or EPA in foods?
    Thanks for the great work!

    • Hi,
      Yes – I focussed on the omega 6 content and how to reduce it.
      I supplied the omega 3 charts of seafood to shwo how to get enough long chain EPA, DHA.
      There is only a little in other animal sources.
