Foods High in Docosahexaenoic Acid (DHA)

Docosahexaenoic acid (DHA) is a type of long-chain omega-3 fatty acid required for the healthy development of the brain and retina (eyesight). (1,2) Further, some studies show cognitive benefits from DHA in older adults, improving memory and learning. (3)

DHA is found primarily in fish and seafood. It can also be created by the body using alpha-linolenic acid (ALA) (4), however, only 3% - 6% of ALAs get converted into DHAs. (5) Since DHA is important for brain development, it is present in breast milk. (6) Pregnant and lactating women should aim to consume 0.2 - 0.3g of DHA per day. (7)

Foods high in DHA include salmon, tuna, canned tuna, mackerel, white fish, canned sardines, squid (calamari), mussels, oysters, cod, fish eggs (roe), pickled herring, and snow crab. Pregnant women should avoid mackerel, swordfish, and tilefish due to their potential mercury content. All other sources should be considered safe and healthy as long as they are fresh and well-prepared.

Below is a list of foods high in DHA ranked by a common serving size. For more, see the extended list of foods rich in DHA, and the nutrient ranking of 200 foods high in DHA fats. For omega 3 fats see the list of foods high in omega 3 fats and foods with a high omega 3 to 6 ratio.

Health Benefits of Docosahexaenoic Acid (DHA)

  • 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. (8) This is especially true of the EPA (eicosapentaenoic fatty acid) and DHA (docosahexaenoic acid) forms of omega 3s.(8,9)
  • Reduced severity of dementia and mental decline - Omega 3 fatty acids may reduce the risk of cognitive decline, but not Alzheimer's. (10) 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. (11) 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. (12) 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. (13)
  • 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. (14) 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. (15)
  • 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 promising results 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. (16)
  • 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. (17)
  • Association with reduced anxiety and depression - Initial studies show a positive association between consuming fish and omega-3 fats reducing anxiety and depression. (18,19) Studies are still preliminary and more studies need to be conducted to provide a stronger link between omega-3s, mental health, and stress relief.
