Foods High in Alpha Linolenic Acid (ALA)
Alpha-Linolenic Acid (ALA) is an essential omega-3 fatty acid that must be obtained via foods. Alpha-linolenic acid is associated with a reduced risk of heart disease (1,2). ALAs can also help relieve inflammation associated with inflammatory bowel disease. (3)
ALA may also provide a wide range of health benefits including reduced cancer risk and regulation of the intestinal flora. (4)
ALA is also important for vegetarians, vegans, or people who do not eat fish or seafood. This is because the body can convert ALAs into the essential long-chain omega-3 fatty acids Docosahexaenoic acid (DHA) and Eicosapentaenoic Acid (EPA). (1) Both DHA and EPA are primarily found in fish and seafood and play a vital role in the brain and eyes. (5) For people who do not consume fish, ALAs are essential to increase levels of DHA and EPA.
The current daily target for ALAs is set at 1.6g per day. (6) This is set as an adequate intake (AI) since there is not enough evidence to establish a recommended dietary allowance (RDA).
How well ALA converts into EPA and DHA is a matter of debate, with some estimating a conversation rate of 3-6%. (7) Pregnant women should consume 0.2-0.3g of DHA a day (8), so you can impute an intake of 5 - 10g of ALAs to meet the daily requirement for DHAs during pregnancy and lactation.
Foods high in ALAs include flaxseeds, chia seeds, walnuts, canola oil, edamame, navy beans, cherimoya, avocados, roasted chicken, and zucchini.
In today's modern diet, most people eat a much higher proportion of Omega 6s than Omega 3s, leading some to look for foods with a good Omega 3 to Omega 6 ratio. For this reason, the amount of omega 3s per omega 6 fat is listed for each food.
Below is a list of top 10 foods highest in ALAs. For more foods high in ALAs see the complete ranking of over 200 foods high in ALA fats. Note: The list of 200+ foods contains many fried foods which are likely fried using soybean or canola oil, and this is why they have a high quantity of ALAs. That said, deep-fried foods are high in saturated-fats, calories, and not part of a healthy diet. For this reason, the top 10 list below excludes these foods.

How much Alpha-Linolenic Acid (ALA) do you need everyday?
Below are the daily adequate intakes (%AI) established for alpha-linolenic acids (ALA). Adequate intakes are used when there is not enough data to formulate a recommended dietary allowance (RDA). The adequate intake of ALAs ranges between 0.5g - 1.6g per day for most people. (11)

Health Benefits of Alpha-Linolenic Acids
- Reduced risk of cardiovascular disease - Studies suggest that patients who consume more ALAs may reduce the incidence of coronary disease and lower mortality in those with coronary disease. (1,2,9,10)
- Alleviation of Inflammation - A diet where 6% of energy intake comes from ALAs reduces markers of inflammation. (11)
- Reduced risk of dementia - In a study involving 7,500 people in Japan, blood levels of ALAs were found to be inversely proportional to risk of dementia. (12) A similar result was also found in the Korean population. (13)
- Possible Protection Against Alzheimer's Disease - ALAs are associated with improvements in the blood brain barrier. (14) In addition to this ALAs help to manufacture DHAs which are concentrated in the brain. The effect of the blood brain barrier is a new theory in Alzheimer's disease currently under study. (14)
- Reduction of triglycerides and blood pressure - While associated primarily with all omega 3 fats (DHA and EPA), ALAs are also associated with a reduction of blood cholesterol (triglycerides). (15,16,17)
