With the entire buzz going around about omega 3 and fish oils, you will surely wonder - which fish contain omega 3? Or better yet, the question would be - which fish contains the most omega 3? Let us answer this important question right now.

You see, fish oil can be found in just about every fish. Makes sense right? But the amount of fish oil you get and the amount of omega 3 fatty acids differ for each fish. Not every fish contain high amounts of omega 3, which is most responsible for the health benefits that the oil provides.

Rich sources of omega 3

To keep things simple, here are some good sources of omega 3 - salmon, mackerel, trout, tuna, sardines, herring and halibut.

It should be noted that the amounts of fish oil in these rich sources also differ depending on the location of the source, the season, whether it was farmed or caught in the wild, as well as the packaging and the method by which it was cooked.

For example, species of salmon sourced in the Atlantic and Coho are more abundant in omega 3 fatty acids. Fresh tuna can give you as much as 1.51 omega 3 content per 100 grams, while canned tuna can only give you as much as 1.18.

What about mercury contamination?

It is unfortunate but these days almost all fish are contaminated with some amounts of mercury. While trace amounts will not be harmful to healthy human beings, it can be dangerous for children, pregnant women and breastfeeding mothers to be exposed to mercury.

Moreover, no matter how healthy you are, if the amount of mercury you take in exceeds the level that your body can eliminate, poisoning is still bound to occur.

If you want to enjoy all the health benefits of omega 3 fatty acids, make sure to eat fish that contains the least amount of mercury and other contaminants. Or else take a pure fish oil capsule and you would not have to worry about it.

According to a report by the FDA, it is king mackerel that contains the highest levels of mercury. Among those with the lowest mercury levels include salmon (fresh, canned or frozen), canned tuna, Atlantic mackerel and herring. Notice too that these fish are also great sources of omega 3 fatty acids. Yet although they are lower in mercury, they still do contain that problem.

A better alternative

You probably know by now what these omega 3 fish oils can do for your cardiovascular health, brain health, joint health, etc. If you want to enjoy all of these potential benefits, ask your doctor and he or she may probably advise you to take in at least one gram of fish oil every day.
