Importance of Omega-3

Omega 3 is an essential fatty acid that has been linked to lower rates of heart disease and possibly cancer at low levels. However, the standard American diet includes less than 1% of Omega 3 intake – most Americans can benefit from a dietary increase!

The “omega symbol” is the last letter of the Greek alphabet. It has been used to represent the beginning and end of a scale or cycle, such as in the phrase “the alpha and omega.”


Omega-3 fatty acids are considered “essential” since the body cannot produce them independently. As a result, we must depend on omega-3 meals to deliver these crucial components in our diets.

Alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA) are the three forms of “omega-3s” (EPA). DHA and EPA, which may be found in seafood like salmon and sardines, are the best sources. On the other hand, ALA may be found in a variety of plant foods, such as nuts and seeds, as well as high-quality animal cuts such as grass-fed beef.

When it comes to getting enough omega-3s in your diet, I recommend eating a variety of omega-3 foods and, in most cases, supplementing. My recommendation is to receive at least 1,000 milligrams of EPA/DHA per day and roughly 4,000 mg of total omega-3s (ALA/EPA/DHA combined) via a mix of both.

What distinguishes some Omega-3 foods from others?

To some extent, the human body can convert ALA into useable DHA and EPA, although this isn’t as efficient as receiving DHA and EPA straight from dietary sources. It’s one of the reasons why, since many types of seafood are naturally rich in DHA and EPA, nutritionists advocate eating wild-caught fish several times each week.

While EPA and DHA are the best omega-3 sources, all forms are suitable and recommended, so start your day with nuts and seeds or have fish for supper. Even though it’s still unclear how effectively ALA converts to EPA and DHA or whether it has any advantages on its own, health experts like those at Harvard Medical School believe that all kinds of omega-3s are essential in the diet.

People who consume the highest omega-3 foods, for example, those in Okinawa, Japan, have lived longer and healthier lives than those who follow a normal diet low in omega-3s. The traditional Okinawa diet, which includes lots of fish, sea veggies, and other fresh food, is said to have eight times the amount of omega-3s found in the average American diet, which is likely one of the reasons why this community is regarded as one of the healthiest in human history.

Other groups who eat many omega-3 foods include those in the Mediterranean area, such as the Spanish, Italians, Greeks, Turks, and French. Researchers discovered that, despite the typical Mediterranean diet being high in overall fat and certain cardiovascular risks, people in these areas have significantly lower rates of heart disease than Americans, possibly due to the heart-healthy omega-3 foods that are regularly included in their meals.

Best vs. Worst Foods

If you walk around any big supermarket, you’ll find that product labels now boast about their omega-3 content more than ever before. However, while omega-3s are now artificially added to various processed foods, including peanut butter, infant formula, cereal, and certain protein powders, it’s still better to acquire your omega-3s from full, natural foods particularly wild-caught seafood.

While not always optimal, these are some of the numerous foods that have been fortified with omega-3 fatty acids and hence contain omega-3s to some degree: pasteurized dairy products, fruit juices, non-organic or cage-free eggs, margarine, soy milk, yogurt, bread, flours, weight-loss beverages, and a variety of baby foods (because research indicates Omega-3s aid proper brain development in newborns).

Microalgae is a common source of EPA and DHA in fortified meals. However, because they naturally provide a fishy odor to meals, these processed goods must be subjected to rigorous chemical purification procedures to hide the taste and odor. As a result, the foods’ fatty acid and antioxidant content are likely to be reduced or changed, rendering them inferior to undamaged, whole food sources.

Omega-3s are also being added to animal feed to increase the amount of omega-3s in consumer dairy, meat, and poultry products. Because food makers are aware that public awareness of the advantages of omega-3s is growing, we should expect to see more and more processed omega-3 meals in the coming years.

Health Advantages

Omega-3 fatty acids have been shown in several studies to aid in the maintenance of the following:

  • Heart and circulatory health (by lowering blood pressure, cholesterol, plaque buildup in the arteries, and the chance of having a heart attack or stroke)
  • Keeping blood sugar levels in check (preventing diabetes)
  • By decreasing inflammation, muscle, bone, and joint pain may be reduced.
  • Assisting in cholesterol balance
  • Mood enhancement and depression prevention
  • Helps with attention and learning by sharpening the intellect.
  • Immunity boosting
  • Irritable bowel syndrome and ulcerative colitis are among the digestive ailments that may be treated.
  • Reducing cancer risk and aiding in the prevention of cancer recurrence
  • Improving one’s appearance, particularly the health of one’s skin

Because there isn’t a universally accepted standard for how much omega-3 we need each day, recommendations vary from 500 to 1,000 milligrams per day, depending on who you ask. Is it simple to get the appropriate amounts? To give you an idea, one can of tuna fish and one modest dish of wild-caught salmon both contain more than 500 mg of total omega-3s.

Most Beneficial Omega-3 Foods

The top 15 omega-3 meals are shown below (percentages based on 4,000 mg of total omega-3s per day):

  1. 1 cup cooked Mackerel from the Atlantic has 6,982 milligrams (174 percent DV)
  2. 1 tablespoon of salmon fish oil has 4,767 milligrams (119 percent DV)
  3. 1 tablespoon of cod liver oil has 2.664 milligrams (66 percent DV)
  4. In 1/4 cup of walnuts, there are 2,664 milligrams (66 percent DV)
  5. Chia Seeds are a kind of chia seed that is: 1 tablespoon contains 2,457 mg of chia seeds (61 percent DV)
  6. In 3 ounces of herring, there are 1,885 milligrams (47 percent DV)
  7. In 3 ounces of Salmon from Alaska (wild-caught), there are 1,716 milligrams (42 percent DV)
  8. 1,597 milligrams flaxseeds (ground) per tablespoon (39 percent DV)
  9. In 3 ounces of Tuna Albacore, there are 1,414 milligrams (35 percent DV)
  10. Whitefish has 1,363 milligrams (34 percent of the daily value) in 3 ounces.
  11. 1 can (3.75 ounces) of sardines has 1,363 milligrams (34 percent DV)
  12. Seeds of hemp: 1 tablespoon contains 1,000 mg of hemp seeds (25 percent DV)
  13. Anchovies: 951 milligrams (23 percent DV) per can/2 ounces
  14. In 1/4 cup of natto, there are 428 milligrams (10 percent DV)
  15. 240 milligrams per 1/2 cup of egg yolks (6 percent DV)

What foods should you avoid, even though they are promoted as rich in omega-3s? Farm-produced fish (particularly salmon), conventional and pasteurized dairy products and krill oil supplements are all examples of conventionally grown meat (non-organic or not grass-fed) (which are made from krill, bottom-feeding shellfish that are usually contaminated).

Always remember that farm-raised fish is inferior to wild-caught fish in terms of contamination and nutritional and omega-3 levels. Antibiotics and pesticides are often found in farm fish, as are low amounts of beneficial minerals like vitamin D. There is additional evidence that farmed fish have higher levels of omega-6 fatty acids and lower levels of omega-3 fatty acids.

Other Natural Omega-3 Sources

  • Butternuts, Brazil nuts, cashews, hemp seeds, and hazelnuts all offer omega-3s in the form of ALA, in addition to walnuts, chia, and flaxseeds (although walnuts, flaxseeds, and chia are definitely the better sources).
  • ALAs may be found in various vegetables, particularly green leafy ones. While ALA omega-3 meals aren’t as excellent as those containing DHA and EPA, you should still include them in your diet because of the fiber and other nutrients they offer. Brussels sprouts, kale, spinach, and watercress are among the vegetables rich in omega-3s.
  • Oils — Omega-3s are found in various oils, mainly in the form of ALAs. Mustard oil, walnut oil, and hemp oil are a few examples. Compared to existing vegetarian omega-3 meals, a novel vegetarian oil called algal oil is gaining appeal since early research suggests it is readily converted to DHA in the body.

Side Effects and Risks

Even when taking up to 20 grams at a time, omega-3s are regarded as quite safe and effective; however, some individuals have slight side effects while taking omega-3 fish oil supplements. The following are some of the possible negative effects of omega-3 fish oil:

  • “Fish burps” or a fishy aftertaste (this is by far the most common complaint, although it should not occur if you take a high-quality supplement)
  • Nausea or stomach discomfort
  • Having trouble going to the restroom regularly (diarrhea)
  • If you consume more than three grams per day, you may get excessive bleeding.
  • Reactions due to allergies
  • Blood sugar levels fluctuate (or complications with diabetes medications)

While most individuals will have no negative effects from eating lots of omega-3 meals and taking supplements regularly, speak to your doctor about any side effects you may be experiencing if you take larger dosages than suggested. Keep in mind that if you have an allergy to most fish, you should avoid using omega-3 supplements made from fish oil since you might have a significant response.

Furthermore, some fish species should never be eaten due to sourcing concerns that result in hazardous contamination, or you risk the extinction of particular seafood populations. When it comes to mackerel (stick to Atlantic mackerel and avoid King and Spanish variants), farmed salmon (choose wild-caught Alaskan salmon), and tuna, be cautious about the type you consume (avoid Atlantic bluefin).


Omega-3 fatty acids are considered “essential” since the body cannot produce them independently. As a result, we must depend on omega-3 meals to deliver these essential components in our diets.

I advocate consuming enough omega-3 meals and supplementing with omega-3 supplements in most circumstances. My recommendation is to receive at least 1,000 milligrams of EPA/DHA per day and roughly 4,000 mg of total omega-3s (ALA/EPA/DHA combined) via a mix of both.

The following are the top 15 omega-3 foods:

  1. Atlantic Mackerel
  2. Fish Oil from Salmon
  3. Cod Liver Oil
  4. Walnuts
  5. Chia Seeds
  6. Herring
  7. Alaskan Salmon
  8. Flaxseeds
  9. Albacore Tuna
  10. Fish that is white in color
  11. Sardines
  12. Hemp Seeds
  13. Anchovies
  14. Natto
  15. Egg Yolks
