Omega-3 fatty acids are essential for maintaining a healthy body and brain. They are considered good fats that support heart health and may reduce the risk of chronic diseases. While supplements are available, it is recommended to get omega-3s from whole foods, such as fatty fish like salmon and mackerel, flaxseed, chia seeds, and walnuts. Plant oils like canola oil and flaxseed oil are also good sources of ALA, a type of omega-3. Adding a mix of these omega-3-rich foods to your diet can help ensure a healthy balance of essential fats and promote overall health.

Eat more fatty fish, like salmon, mackerel, sardines, and trout
Eating fatty fish is one of the best ways to add more omega-3 to your diet. Salmon, mackerel, sardines, and trout are all fatty fish that are rich in omega-3 fatty acids. Aim for two servings of fatty fish per week to meet the recommended intake of omega-3 fatty acids.
Salmon is one of the most nutrient-dense foods on the planet. It is a great source of high-quality protein and various nutrients, including large amounts of vitamin D, selenium, and B vitamins. Studies have shown that regularly eating fatty fish like salmon can lower your risk of heart disease, dementia, and depression. When choosing salmon, consider the source. There are some differences between wild and farmed salmon in terms of nutrient composition, fatty acid content, and organic contaminants.
Mackerel are small, fatty fish that are commonly smoked and eaten as whole fillets in many countries. They are a good source of omega-3 fatty acids and provide a range of health benefits.
Sardines are an inexpensive type of fish with a high content of omega-3 polyunsaturated fatty acids (n-3 PUFA). They are also a source of many other essential nutrients, including minerals, vitamins, and amino acids. Regular consumption of sardines can help reduce the risk of mortality associated with coronary heart disease.
Trout is another fatty fish that is a good source of omega-3 fatty acids. It provides similar health benefits to the other fatty fish mentioned.
By including a variety of fatty fish in your diet, you can increase your intake of omega-3 fatty acids and reap the associated health benefits.

Consume plant-based sources of ALA, such as flaxseed, chia seeds, and walnuts
Omega-3 fatty acids are incredibly important for health and can be obtained from whole foods. One way to add more omega-3s to your diet is by consuming plant-based sources of alpha-linolenic acid (ALA), such as flaxseed, chia seeds, and walnuts.
Flaxseed, also known as linseed, is a rich source of plant-based omega-3s. While flaxseed oil provides about 7 grams of ALA per tablespoon, it is not as effective as fish oil because ALA needs to be converted into eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) to have the beneficial effects attributed to omega-3s. However, only a small fraction of ALA is converted into EPA and DHA due to a limited supply of enzymes. Nonetheless, flaxseed oil can still provide a significant amount of omega-3s and is a good option for those concerned about mercury in fish.
Chia seeds are another excellent source of plant-based omega-3s. About 60% of the fats in chia seeds are ALA, making them an even better source of ALA than flaxseed. Chia seeds are also rich in fibre, antioxidants, minerals, and protein. They have been linked to improved risk factors for heart disease and diabetes, as well as benefits for digestion and gut health. A standard 1-ounce (28-gram) serving of chia seeds provides 5 grams of protein and eight essential amino acids.
Walnuts are a third plant-based source of ALA omega-3s. They are also very nutritious and loaded with fibre, copper, manganese, vitamin E, and plant compounds. It is important to consume the walnut skin, as it contains most of the walnut's phenol antioxidants, which offer additional health benefits.
While these plant-based sources of ALA are a good way to boost your omega-3 intake, it is important to note that ALA is not as efficiently utilised by the body as EPA and DHA, which are predominantly found in animal-based sources such as fatty fish. Nonetheless, including a variety of plant-based ALA sources in your diet can help ensure adequate omega-3 intake and provide additional nutritional benefits.

Try omega-3 supplements like fish oil, cod liver oil, or algal oil
Omega-3 supplements are a great way to increase your omega-3 intake, especially if you don't eat fish or follow a vegetarian or vegan diet. Fish oil, cod liver oil, and algal oil are popular omega-3 supplements.
Fish oil is derived from the flesh of fatty fish, such as tuna, mackerel, and salmon. It contains omega-3 fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These omega-3 fatty acids are considered \"good oils\" that offer various health benefits. Fish oil supplements usually contain higher concentrations of fish oil and may be available in capsules for those who prefer not to use oily supplements. However, it's important to note that fish oil supplements may have a strong taste that some may find unpleasant.
Cod liver oil is a specific type of fish oil derived from the livers of codfish, typically Atlantic cod or Pacific cod. In addition to omega-3 fatty acids, cod liver oil contains vitamins A and D due to the cod's diet of phytoplankton and microalgae. These vitamins provide additional health benefits, but excessive amounts can be harmful. Therefore, it's important to consult a doctor before taking cod liver oil supplements to ensure safe and appropriate dosage.
Algal oil is a vegetarian source of omega-3, particularly DHA, and some algal oils also contain EPA. This supplement is a good alternative for those who do not wish to consume fish products.
When considering omega-3 supplements, it's important to note that there is currently no standard recommended dosage for EPA or DHA. The appropriate dosage may vary depending on individual factors, and taking too much can have risky side effects. It is always recommended to consult a healthcare professional before taking any supplements to ensure they are safe for you and to determine the correct dosage.

Include omega-3-fortified foods like eggs, yogurt, and milk in your diet
Omega-3-fortified foods are a great way to increase your omega-3 intake. Here are some tips to include more omega-3-fortified foods, such as eggs, yogurt, and milk, in your diet:
Eggs
When it comes to eggs, there are several options available, including conventional, organic, omega-3-enriched, pastured, free-range, and cage-free. If you want to focus on omega-3s, opt for omega-3-enriched eggs. These eggs are laid by hens that are fed an omega-3-supplemented diet, often including flax seeds. Omega-3-enriched eggs have significantly higher omega-3 content than conventional eggs and can be a simple way to boost your omega-3 intake.
Yogurt
Yogurt can be an excellent source of omega-3, especially when fortified. A study found that consuming yogurt fortified with long-chain Omega-3 showed positive associations with increased plasma levels of Omega-3 in the body. This suggests that fortified yogurt can be an effective way to increase your omega-3 intake and potentially improve cardiovascular health.
Milk
Milk is another dairy product that is sometimes fortified with omega-3, specifically DHA Omega-3. DHA is important for brain and eye health. Look for organic milk from pasture-raised cows, which is often marketed as having DHA Omega-3. Including this type of milk in your diet is an easy way to get more omega-3s, especially for children who enjoy drinking milk.
Remember, while omega-3-fortified foods can be beneficial, it's also important to consume a balanced and varied diet that includes other whole-food sources of omega-3s, such as fatty fish, seeds, and nuts.

Eat red meat from grass-fed animals, which has more omega-3 than regular meat
Omega-3 fatty acids are essential nutrients that support heart health and help all the cells in your body function as they should. They are a vital part of your cell membranes, providing structure and supporting interactions between cells. While they are important to all your cells, omega-3s are concentrated in high levels in the cells in your eyes and brain.
One way to add more omega-3s to your diet is to eat red meat from grass-fed animals. Research spanning three decades suggests that grass-based diets can significantly improve the fatty acid composition of beef, albeit with variable impacts on overall palatability. Grass-fed beef has been shown to enhance total conjugated linoleic acid (CLA) (C18:2) isomers, trans vaccenic acid (TVA) (C18:1 t11), a precursor to CLA, and omega-3 (n-3) FAs on a g/g fat basis.
A standard serving of grass-fed top sirloin beef has about 65 mg of omega-3 fats, about 50% more than grain-fed beef. While grass-fed beef has more omega-3 oils than grain-fed beef, the amount is still fairly small compared to other sources. It would take 4.5 pounds of grass-fed beef daily for a man to reach the recommended intake level of 1,600 mg of omega-3s per day.
Grass-fed beef also has other nutritional advantages. Grass-fed beef has higher levels of natural α-tocopherol (vitamin E), which acts post-mortem to delay oxidative deterioration of the meat. It also has higher levels of GT, a tripeptide composed of cysteine, glutamic acid, and glycine, which functions as an antioxidant.
In addition to beef, other types of meat from grass-fed animals can also be good sources of omega-3s. For example, pasture-raised chicken and pork have been found to have significantly higher levels of omega-3 fatty acids, including EPA and DHA, the long-chain omega-3s.
