3 Things You Should Know About Omega 3 Foods
We all know that omega 3 foods are good for you. As an essential fatty acid, omega-3 must be consumed through our food since it cannot be synthesized in the body. Omega-3s are associated with inflammation, since they mediate the release of anti-inflammatory cell messengers called prostaglandins, thromboxanes, and leukotrienes.

But the equation isn’t as simple as omega 3s = anti-inflammation. Here are 3 important caveats to understand when it comes to this star fatty acid.
1. Omega 3 foods are not created equal
You’ve heard the fanfare about walnuts and flaxseeds: “They are excellent omega 3 foods!” The most important fact to know about omega 3 is that the omega 3 found in plant sources not well absorbed. Enjoy some walnuts, but don’t consider this snack a source of omega-3.
There are three types of omega-3: ALA, EPA and DHA. Plant sources, like those walnuts, contain only ALA. In order to reap anti-inflammatory benefits from ALA, the body must convert it into the useable form of EPA and DHA. This conversion, however, creates only a tiny quantity of EPA or DHA (source). As a result, many vegetarians and vegans are deficient in omega-3.
Vegetarian sources of EPA and DHA include pastured eggs and grassfed full-fat dairy products. The one vegan source of DHA is algae, although many experts are waiting for more research to determine if algae DHA is as potent as animal-source DHA.
2. Omega 6 and omega 3 foods are a balancing act
Like omega-3, omega-6 is an essential fatty acid that sends inflammation-mediating messages. Before I discuss the relationship between omega-3 and omega-6, I want to highlight a few similarities and differences between these fatty acids.
Omega 6…

is consumed primarily in the form of linoleic acid
in the body, it converts into gamma linoleic acid (GLA) arachidonic acid (AA)
AA, once incorporated into a cell, signals the release of pro-inflammatory messengers
GLA can be converted into DGLA, which signals the release of anti-inflammatory messengers
Omega 6 is consumed in highly excessive levels in the Standard American Diet, primarily due to the intake of omega-6-heavy vegetable oils (corn/soy/safflower/canola oil)
Omega 3…
is in three forms discussed above: ALA, DHA and EPA
DHA and EPA, once incorporated into a cell, signal the release of anti-inflammatory messengers
Omega 3 foods are highly deficient in the Standard American Diet
The balance of omega 6 and omega 3 comes down to inflammation. While we consider inflammation bad, the body must inflame in order to heal. The problem of chronic inflammation arises when the body lacks the resources required to anti-inflame.
Omega 3 and omega 6 are antagonistic, competing for storage space in cell membranes. Excess omega-6, in the form of AA, promotes inflammation by attaching to cell membranes and signaling the release of pro-inflammatory messengers. Because the cell membranes are filled up with omega-6, there is little room for DHA/EPA to find a spot and tell the cell to produce anti-inflammatory messengers.
You may have read about the omega-3 to omega-6 ratio. While our hunter-gatherer ancestors consumed roughly a 1:1 ratio of omega 6 to omega 3, researchers estimate that today we consume an average ratio of 20:1.
How did this ratio get flipped? The modern diet has replaced omega-3-rich fats (such as butter and egg yolks) with highly-processed vegetable oils. Canola, corn, soybean, safflower and sunflower oil all contain too much omega-6 to be used on a regular basis.
Research suggests that it is not necessarily that specific ratio of omega-3 to omega 6 that creates inflammation, but rather the lack of omega 3.
Mark Sisson at Mark’s Daily Apple summarizes,
It appears as if the problem with low ratios of omega-3 to omega-6 is the lack of omega-3, not so much the omega-6. In studies that replace saturated fats with omega-6 fats, the only ones that show benefit are those that also include omega-3s with the omega-6s, while those that replace SFA with just omega-6 increase the risk of death. As long as you’re eating enough fish and other seafood, pastured animals and their fat (and eggs), and/or high quality fish oil supplements, whole food sources of omega-6 shouldn’t increase inflammation. The ratio is a helpful way to monitor your omega-3 and omega-6 intake, but it’s not a physiological law.
Does that mean you are safe to eat omega-6-rich vegetable oils if you take a spoonful of fish oil? No, for the primary reason that these highly processed non-food oils offer no nutrient value (and no flavor, either). I recommend swapping veggie oils with omega-3-rich ghee instead.
3. Fish consumption may trump fish oil
Experts agree that the best sources of omega-3 (meaning, the absorbable forms EPA and DHA) are wild-caught, cold-water fish, consumed at least three times per week. Pastured eggs and dairy also provide EPA and DHA.
Excellent sources of EPA and DHA include:
- Salmon
- Herring
- Sardines
- Anchovies
- Trout
- Oysters
- Mackerel (not King mackerel, which is high in mercury)
- Pastured eggs
- Grassfed dairy products, particularly grassfed butter and ghee
“Can’t I simply rely on fish oil for my omega-3s?” Surprisingly, research is mixed about the efficacy of fish oil supplementation, as Chris Kresser explores in his article, Should You Really Be Taking Fish Oil?
