Omega-3 fatty acids are crucial for maintaining good health and are known for their benefits to the heart and reduced inflammation. While salmon is widely recognized for its omega-3 content, there are several other food sources that also provide this essential nutrient. Exploring these alternatives can help you diversify your diet while ensuring you receive adequate omega-3s.
-
Omega-3 fatty acids are essential fats that play important roles in your health, such as supporting your heart and reducing inflammation.
-
Apart from salmon, other foods high in omega-3s include sardines, anchovies, caviar, and chia seeds.
-
You can also take omega-3 supplements or cod liver oil supplements.
While salmon is an outstanding source of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA)—offering 1.24 grams of DHA and 0.59 grams of EPA per 3-ounce serving—numerous other shelf-stable options can help you meet your daily omega-3 needs.
1. Cod Liver Oil

Omega-3 content per serving: Cod liver oil features higher concentrations of DHA and EPA than salmon, supplying 1.5 grams of DHA and 0.938 grams of EPA per tablespoon.
Regular use of cod liver oil can lower markers of inflammation and improve cholesterol levels.
Furthermore, cod liver oil is rich in vitamin A for immune function, cognitive health, and reproductive abilities, as well as vitamin D for immune and bone health.
How to use it: Cod liver oil is sold as both a liquid and in capsules. Consulting your healthcare provider on appropriate dosages is advisable.
2. Sardines

Omega-3 content per serving: Sardines offer a similar omega-3 content as salmon, delivering 0.74 grams of DHA and 0.45 grams of EPA per 3-ounce serving.
Including sardines regularly in your diet can limit the need for separate omega-3 supplements. They also provide protein, calcium, potassium, magnesium, iron, and zinc.
Moreover, sardines have a lower mercury content compared to salmon, as their smaller size and short lifespan help them accumulate less of this heavy metal. “Because sardines are relatively small, short-lived, and low on the food chain, they accumulate significantly less mercury than larger fish,” explains Steph Greunke.
How to use it: Canned sardines offer a convenient alternative to cooking raw or frozen fish. “Simply add them to a salad, combine with mayo for a sandwich, or enjoy with crackers,” suggests Greunke.
3. Anchovies

Omega-3 content per serving: Anchovies are tiny fish that boast a remarkable omega-3 content, providing 1.09 grams of DHA and 0.648 grams of EPA per 3-ounce serving.
Additionally, anchovies are rich in vitamins and minerals such as calcium, iron, and selenium.
“Anchovies also provide iodine, which is essential for proper thyroid function,” Greunke adds. Iodine is crucial for producing thyroid hormones that help regulate metabolism, energy levels, body temperature, and growth.
How to use it: Anchovies serve well in pastas and salads or can be enjoyed straight from the can or on toast. “Choose varieties that are wild or sustainably sourced and packed in natural oil or water,” recommends Greunke.
4. Omega-3 Supplements

Omega-3 content per serving: Omega-3 supplements are long-lasting and provide an appealing alternative to salmon. They typically contain between 500–2,000 milligrams of combined EPA and DHA per serving.
Health experts generally recommend a daily intake of 250–500 mg of EPA and DHA for adults.
How to use it: Omega-3 supplements can be taken anytime and are suitable for individuals who dislike seafood, which is often the main omega-3 source.
5. Caviar

Omega-3 content per serving: Though caviar is often considered an indulgence, it is also a rich and stable source of omega-3s, with two tablespoons yielding 1.2 grams of DHA and 0.88 grams of EPA—much more concentrated than salmon.
Caviar is also abundant in vitamins and minerals, particularly B12, which supports neurological functions, metabolism, red blood cell production, and DNA synthesis. It also contains choline, vital for neurotransmitter production and fetal brain development.
How to use it: Caviar pairs delightfully with crackers or blinis and enhances cheese platters and snack spreads.
6. Flax Oil

Omega-3 content per serving: Flaxseed oil is the richest plant-based source of alpha-linolenic acid (ALA), offering 7.26 grams of ALA per tablespoon.
ALA is known for its anti-inflammatory properties, and studies indicate that increasing ALA intake may reduce the risk of heart disease.
How to use it: Flaxseed oil should not be used for cooking. Instead, consider it as a supplement or a dressing for salads and grain dishes.
7. Chia Seeds

Omega-3 content per serving: Chia seeds are nutrient-dense, providing a stable source of ALA, alongside fiber, magnesium, selenium, and zinc. They offer 5.06 grams of ALA per ounce.
In contrast to animal sources of omega-3s such as salmon, chia seeds are loaded with fiber, which supports gut health by fostering beneficial bacteria in the intestines and promoting regularity.
Moreover, chia seeds are high in magnesium, a crucial mineral for maintaining balanced blood sugar and blood pressure levels.
How to use it: Incorporate chia seeds into oatmeal, baked goods, or create a chia pudding for a quick and healthy breakfast.
Exploring these various sources of omega-3 fatty acids not only can enhance your diet but also ensure you reap the diverse health benefits these essential fats offer. Incorporating a range of these foods into your meals can lead to improved overall health and well-being.
