Omega-3 fatty acids have various benefits for your body and brain.
Many mainstream health organizations recommend a minimum of 250–500 mg of omega-3s per day for healthy adults.
You can get high amounts of omega-3 fats from fatty fish, algae and several high-fat plant foods.
Here is a list of 12 foods that are very high in omega-3.

1. Mackerel
In Western countries, they are commonly smoked and eaten as whole fillets.
Mackerel are incredibly rich in nutrients — a 3.5-ounce (100-gram) serving packs 200% of the Reference Daily Intake (RDI) for vitamin B12 and 100% for selenium (4).
On top of that, these fish are delicious and require little preparation.
2. Salmon
Salmon is one of the most nutrient-dense foods on the planet.
It contains high-quality protein and a variety of nutrients, including large amounts of magnesium, potassium, selenium and B vitamins.
Studies show that people who regularly eat fatty fish, such as salmon, have a lower risk of diseases like heart disease, dementia and depression
3. Cod Liver Oil
Cod liver oil is more of a supplement than a food.
As the name implies, it is oil extracted from the livers of cod fish.
Not only is this oil high in omega-3 fatty acids, but a single tablespoon is loaded with vitamins D and A — 338% and 270% of the RDIs, respectively.
Therefore, taking just one tablespoon of cod liver oil more than satisfies your need for three incredibly important nutrients.
However, don't take more than one tablespoon at a time, because too much vitamin A can be harmful.
4. Herring
Herring is a medium-sized, oily fish. It is often cold-smoked, pickled or precooked, then sold as a canned snack.
Smoked herring is a popular breakfast food in countries like England, where it’s served with eggs and called kippers.
A standard smoked fillet contains almost 100% of the RDI for vitamin D and selenium and 50% of the RDI for vitamin B12
5. Oysters
Shellfish are among the most nutritious foods you can eat.
In fact, oysters contain more zinc than any other food on the planet. Just 6–7 raw oysters (3.5 ounces or 100 grams) pack 600% of the RDI for zinc, 200% for copper and 300% for vitamin B12. Oysters are usually eaten as an appetizer, snack or whole meal. Raw oysters are a delicacy in many countries
6. Sardines
Sardines are very small, oily fish that are commonly eaten as a starter, snack or delicacy.
They’re highly nutritious, especially when eaten whole. They contain almost every nutrient your body needs.
One cup (149 grams) of drained sardines provides over 200% of the RDI for vitamin B12 and over 100% for vitamin D and selenium
7. Anchovies
Anchovies are tiny, oily fish often bought dried or canned.
Usually eaten in very small portions, anchovies can be rolled around capers, stuffed in olives or used as pizza and salad toppings.
Because of their strong taste, they are also used to flavor many dishes and sauces, including Worcestershire sauce, remoulade and Caesar dressing.
Anchovies are a great source of niacin and selenium, and boned anchovies are also rich in calcium
8. Caviar
Caviar consists of fish eggs, also called roe.
Widely regarded as a luxurious food item, caviar is most often used in small quantities as a starter, taster or garnish.
Caviar is high in choline and exceptionally low in omega-6 fatty acids
9. Flaxseeds
Flaxseeds are small brown or yellow seeds. They are often ground, milled or used to make oil.
These seeds are by far the richest whole-food source of the omega-3 fat alpha-linolenic acid (ALA). Therefore, flaxseed oil is often used as an omega-3 supplement.
Flaxseeds are also very high in fiber, vitamin E, magnesium and other nutrients. They have a great omega-6 to omega-3 ratio compared to most oily plant seeds
10. Chia Seeds
Chia seeds are incredibly nutritious — they’re rich in manganese, calcium, phosphorus and various other nutrients.
A standard 1-ounce (28-gram) serving of chia seeds contains 4 grams of protein, including all eight essential amino acids.
11. Walnuts
Walnuts are very nutritious and loaded with fiber. They also contain high amounts of copper, manganese, vitamin E and important plant compounds.
Make sure not to remove the skin, as it packs most of walnuts’ phenol antioxidants — which offer important health benefits.
12. Soybeans
Soybeans are a good source of fiber and vegetable protein.
They also contain high amounts of other nutrients, including riboflavin, folate, vitamin K, magnesium and potassium.
However, soybeans are also very high in omega-6 fatty acids, so they should not be relied on as a sole omega-3 source. Studies suggest that eating too much omega-6 may cause inflammation
13. Any Other Foods?
Keep in mind that sections 1–8 discuss foods that contain the omega-3 fats EPA and DHA, which are found in some animal foods, seafood and algae.
Conversely, sections 9–12 handle foods that provide the omega-3 fat ALA, which is inferior to the other two.
Although not as high in omega-3 as the foods above, many other foods have decent amounts.
These include pastured eggs, omega-3-enriched eggs, meats and dairy products from grass-fed animals, hemp seeds and vegetables like spinach, Brussels sprouts and purslane.



The Bottom Line
As you can see, it’s relatively easy to obtain plenty of omega-3s from whole foods.
Omega-3s provide numerous benefits to your body, such as fighting inflammation, Alzheimer's disease and cancer.
However, if you don't eat many of these foods and think you may be lacking in omega-3s, consider taking omega-3 supplements.

It was well informing to read an article like this. Caviar is for picky people. You either love or hate it. I personally happen to love it. This stuff is expensive so learn everything you can about the various types of caviar before you even think about buying it. Because caviar is extremely perishable, once it is imported and repackaged, the shelf life is only about 3 to 4 weeks unopened. Once opened, it’s good for about three days and that’s if refrigerated at an ideal temperature of 30 degrees F. So ask about dates. I never had this problem when ordering from https://osetrus.com/ Then know how to take good and proper care for Caviar. My orders would come relatively fast too. One more thing though, from my personal experience. There is basically no shelf life on expensive caviar, two or three days so plan to plan accordingly. Or you would have wasted a lot of money and a lot of good Caviar. Other than that, I'm always glad to see someone who is just like me so well informed on fish products, keep it up.

I also know that caviar is having a lot of vitamins and minerals. Different omega 3 fat, vitamins that are good for health as well.
I like to order it at https://globalseafoods.com/products/ossetra-sturgeon-caviar-royal-crown where are a lot of options. Black caviar is a little bit expensive but my favorite is red.

I also know that fish fat contains omega 3.

As caviar continues to captivate the hearts and palates of food enthusiasts, the future of this luxurious delicacy remains bright. Sustainable practices, innovation in aquaculture, and conservation efforts are paving the way for a more responsible and inclusive caviar industry. The appreciation for caviar is expanding, reaching new markets and diverse culinary landscapes.


Caviar, with its exquisite taste and luxurious appeal, has established itself as a symbol of sophistication and indulgence. From the traditional methods of harvesting to sustainable practices, caviar has evolved over time, yet it retains its allure and charm. Whether enjoyed in fine dining restaurants or savored at home, caviar provides a sensory experience like no other, offering a glimpse into the opulent world of gastronomy.
