Top 10 Foods Highest in Omega 3 Fatty Acids

Omega-3 fatty acids are a type of polyunsaturated fat associated with various health benefits including reducing the risk of heart disease (1,2), reducing the risk and severity of dementia (3), alleviating inflammation in arthritis (4), and reduction of triglyceride levels. (5) Omega 3s are 'essential fats' as they cannot be made in the body, and must be obtained via diet.

The 3 principal omega-3 fatty acids are:

Note: Most health benefits of omega 3s are attributed to DHA and EPA forms of omega 3s. This is partly due to the high concentration of DHA in the brain, and also because ALAs have not been extensively studied. (6) The body can convert ALA fats from plant foods, however, the efficiency of conversion varies from person to person, with average estimates suggesting that 6% of ALAs get converted to EPA, while 3.8% get converted to DHA. (7) ALAs are not totally without benefits, and more studies need to be conducted to fully understand the role of ALAs. (8,9)

High omega-3 foods include flaxseeds, chia seeds, fish, walnuts, tofu, shellfish, canola oil, navy beans, brussels sprouts, and avocados. The adequate intake (AI) for ALA omega 3 fats is 1.6g per day (10). No adequate intake target for EPA and DHAs exists, so 1.6g is presented in this article to make it easier to compare sources of omega 3s.

Below are the top 10 foods high in omega 3 fatty acids. For more, see the list of foods with a high omega 3 to omega 6 ratio, and the complete list of over 200 foods high in omega 3s.

Below are the daily adequate intakes (%AI) established for omega 3 foods. Adequate intakes are used when there is not enough data to formulate a recommended dietary allowance (RDA). The adequate intake of omega 3 fats ranges between 0.5g - 1.6g per day for most people. (10)

Health Benefits of Omega 3s

  • Reduced risk of cardiovascular disease - Studies suggest that consumption of 1 gram of omega 3s per day helps reduce the risk of all-cause mortality in patients with known coronary heart disease. (1) This is especially true of the EPA (eicosapentaenoic fatty acid) and DHA (docosahexaenoic acid) forms of omega 3s.(1,2)
  • Reduced severity of dementia and mental decline - Omega 3 fatty acids may reduce the risk of cognitive decline, but not Alzheimer's. (3) The association is stronger for people over 55 years old. Linking diet to health is difficult, however, and studies do not always show benefits for mental health. (12) With that being said, there is very little harm in consuming a 1g supplement of omega 3 or eating more omega 3 foods.
  • Alleviation of arthritis and inflammation - Several studies associate omega 3 consumption with alleviation and modulation of pain from swollen arthritic joints. (4) One double-blind randomized trial gave participants 2 doses (1.8g and 2.1g) of omega 3 in the form of EPA and DHA. Patients who consumed the omega3s vs placebo showed improvement in arthritis based on a physician's evaluation and were also able to reduce the amount of pain medication they consume. (12)
  • Reduced triglyceride levels - As little as 1 gram per day of fish oil ( 0.21 g EPA and 0.12 g DHA) reduce triglyceride levels in people with high blood cholesterol and triglycerides. (5) Higher doses of omega 3s (EPA and DHA) also help reduce triglyceride levels with little ill effect on total blood cholesterol. For people with blood triglycerides over 500mg/dl a prescription of omega 3 supplements is approved by the US Food and Drug Administration as an effective treatment. (13)
  • Improvement of ADHD in children - At least one double-blind dose-response study found that omega 3 supplements in addition to a drug of choice (methylphenidate) showed significant clinical improvement over those who did not take omega 3 supplements. Children were given 100mg - 400mg of omega 3 depending on weight. More studies need to be done to confirm this finding. (14)
  • Enhanced Sleep - Omega 3 consumption is associated with better sleep. In one study participants were either given salmon 3 times a week or a similar serving of a food low in omega 3s like pork, chicken, or beef. The people who consumed salmon experienced lower sleep latency (fell asleep faster), maintained better heart rate variability, and self-reported better sleep quality and daily functioning. (15)
  • Association with reduced anxiety and depression - Initial studies show a positive association between consuming fish and omega-3 fats reducing anxiety and depression. (16,17) Studies are still preliminary and more studies need to be conducted to provide a stronger link between omega-3s, mental health, and stress relief.

Omega 3 for Vegans and Vegetarians

Vegans and vegetarians tend to have lower levels of DHA and EPA Omega 3 fats. Both these forms of omega 3s are found mainly in fish products (18).

Vegans and vegetarians can convert ALA omega 3 fats from plants into DHA and EPA, however, the process is slow, and is aided by a good omega 3 to 6 ratio. (19)

Consumption of both ALA and EPA appear to have little effect on the DHA levels of breast milk. (19) DHA is important for brain development, (20) so consumption of DHA or DHA supplements is advised for lactating vegans. (19)

Vegans and vegetarians should consider an omega-3 supplement, such as those from algal oil. (18) Interestingly, quinoa also contains some DHA and can be a good food for vegetarians. One cup of cooked quinoa provides 0.028g (28mg) of DHA.

Is Algae and Algal Oil a Good Source of Omega 3s?

Certain types of algae and agal supplements can be a good source of omega3s, particularly for people on a plant-based (vegetarian) diet who don't eat fish and are ok with eating algae.

This study found that algal supplements are an effective way to increase levels of healthy DHAs in vegetarians. (21)

This study found that consumption of the microalgae Phaeodactylum tricornutum (PT) created a similar increase in omega 3 blood levels as those taking fish oil supplements. (22)

Does Olive Oil Provide Omega 3 Fats?

While olive oil is a heart-healthy fat it only provides 0.1g (6% AI) of omega 3s per tablespoon. This is considerably lower than the 1.28g (80% AI) of omega 3s in a tablespoon of canola oil.

Are Eggs High in Omega 3s?

Eggs that advertise high omega 3 content are typically from hens given foods high in omega 3s. These foods can include flax seeds, chia seeds, or even fish oil. In order to get DHA, and EPA from eggs, the chickens should be fed a food that also has those fats. (23)

About Nutrient Targets

Setting targets can provide a guide to healthy eating.

Some of the most popular targets include:
  • Daily Value (%DV) - The daily value (%DV) is a general guideline for consumption that will prevent deficiency of a particular nutrient in most people. The %DV refers to the percentage of an amount that's found in a single serving of a food. It also accounts for absorption factors. It is set by the U.S. FDA.
  • Recommended Dietary Allowance (%RDA) - The RDA sets an average daily dietary intake level that is sufficient to meet the nutrient requirements of nearly all (97.5%) healthy individuals. It's more specific than the daily value, and varies by age and gender. The RDA is set by the US National Institutes of Health.
  • Reference Dietary Intake (%RDI) -The reference dietary intake is similar to the recommended daily allowance, but is specific to age and gender. The RDI for amino acids is set by the U.N. World Health Organization.
  • Adequate Intake (%AI) - This value is primarily used in reference to omega-3 and omega-6 fats. The Adequate Intake is set by the U.S. Institute of Medicine. Because there is less evidence to determine the ideal targets for consumption of these nutrients, the specific amount is considered to be less reliable. Using the term Adequate Intake, rather than one of the other terms, helps to emphasize that the ideal intake of that particular nutrient has not yet been scientifically determined.
