Omega-3 content in 100g of chicken
The amount of omega-3 fatty acids in chicken meat is relatively low and can vary depending on the cut, cooking method, and crucially, the animal's diet. For a standard 100g serving of cooked, lean chicken breast, the omega-3 content is typically around 48mg, a figure that includes combined EPA, DPA, and DHA. Other sources suggest slightly different figures, with one Australian food database indicating total long-chain omega-3s in baked chicken breast at just over 18mg per 100g.
Chicken thigh meat tends to have a slightly higher fat content and, as a result, a marginally higher concentration of omega-3s. For example, a study from 2010 found that thigh meat from conventionally fed chickens had about 0.06 g (60 mg) of EPA, DPA, and DHA per 100g. It is important to recognize that these amounts are not a significant source of omega-3s for humans when compared to marine sources.
The crucial role of the chicken's diet
The omega-3 content in chicken is not fixed; it is directly influenced by what the birds are fed. Commercial chicken feed is often high in omega-6 fatty acids, leading to a high omega-6 to omega-3 ratio in the final meat product. However, poultry producers can enrich the meat with omega-3s by supplementing the chickens' diet with specific ingredients:
- Flaxseed: Rich in alpha-linolenic acid (ALA), flaxseed can be added to chicken feed to boost ALA levels in the meat and eggs.
- Fish Oil and Fish Meal: These marine-based additives provide a direct source of long-chain EPA and DHA, effectively increasing the omega-3 content in the meat. Some studies show that this method can produce chicken meat that is labeled “high in omega-3 fatty acids”.
- Microalgae: A sustainable, plant-based source of DHA, microalgae can be used to enrich poultry products with omega-3s without imparting a fishy flavor, which can sometimes be a side effect of using fish oil.
Chicken vs. omega-3-rich foods: a comparison
To put the omega-3 content of chicken into perspective, it is useful to compare it with other common dietary sources. Fatty fish and some plant-based foods offer far higher levels of this essential nutrient.
| Food (100g serving) | Approx. Omega-3 (EPA + DHA) | Notes |
|---|---|---|
| Standard Chicken Breast (cooked) | ~48 mg | Levels vary, often minimal. |
| Standard Chicken Thigh (cooked) | ~60 mg | Slightly higher than breast due to higher fat. |
| Atlantic Salmon | ~2,000 - 2,800 mg | One of the richest sources. |
| Cod Fillet | ~260 mg | Leaner fish, still higher than chicken. |
| Sardines | ~1,500 mg | Excellent marine source. |
| Chia Seeds | >17,000 mg (ALA) | Plant-based, requires conversion. |
| Walnuts | >2,500 mg (ALA) | Plant-based, requires conversion. |
This comparison clearly shows that while chicken can contain small amounts of omega-3s, it should not be considered a primary source for meeting daily requirements. Dietary diversity is key, and incorporating fatty fish or plant sources alongside chicken is the best strategy for adequate intake.
Understanding the different types of omega-3
There are three main types of omega-3 fatty acids: Alpha-linolenic acid (ALA), Eicosapentaenoic acid (EPA), and Docosahexaenoic acid (DHA).
- ALA: Found primarily in plant sources like flaxseed and walnuts. The human body must convert ALA into EPA and DHA, but this process is inefficient.
- EPA and DHA: Found mainly in marine sources such as fatty fish and algae. These are the biologically active forms readily used by the body for important functions.
Standard chicken meat primarily contains ALA, unless the chicken's diet has been specifically supplemented with EPA and DHA sources like fish oil or algae. This is an important distinction when considering the nutritional impact.
Health benefits of omega-3 fatty acids
Omega-3 fatty acids are vital for overall health and play numerous roles in the body. The benefits extend beyond heart health and include crucial functions in the brain and eyes.
- Cardiovascular Health: Omega-3s can reduce triglycerides, lower blood pressure, and decrease the risk of irregular heartbeats, helping to prevent heart disease and stroke.
- Brain Function and Mental Health: These fatty acids are essential for building brain cells. Research indicates they may help alleviate symptoms of depression and anxiety.
- Anti-Inflammatory Properties: Omega-3s possess anti-inflammatory effects that can be beneficial for conditions like rheumatoid arthritis and potentially reduce symptoms of asthma.
- Eye Health: DHA is a key structural component of the retina. Adequate omega-3 intake is linked to a reduced risk of macular degeneration and can help with dry eye disease.
- General Well-being: A deficiency can lead to dry skin, hair changes, fatigue, and poor concentration, highlighting their importance in cellular function.

Conclusion
In conclusion, a 100g portion of standard chicken meat is not a significant source of omega-3 fatty acids. The content is notably low compared to fatty fish and marine-based products. While chicken's diet can be modified to increase its omega-3 levels, this is not a feature of most conventionally raised poultry. For those seeking to boost their omega-3 intake, a dietary strategy that includes fatty fish, fortified products, or plant sources like flaxseed and walnuts is far more effective. Chicken remains a valuable source of lean protein and other nutrients, but it is not the food to rely on for your omega-3 needs.
