More and more people are trying to increase their consumption of omega 3s. The obvious way to do this is by eating fish more often. However, they really want more omega 3s while eating less seafood. Put another way, they are trying to increase their nutrition intake and decrease the risk of toxicity.
Some people just love eating fish, even as frequently as five-to-six servings per week. They are prepared for the possibility of having ocean contaminants along with their dinner. In their mind, there is no discussion. Nevertheless, if your main goal is getting omega 3 benefits, then a better choice is not eating so much fish but using a supplement instead - assuming it is a good one.
Most consumers that are seafood lovers already know about the different natural and industrial toxins they get as part of the food chain - heavy metals, PCBs etc. Farmed fish are not an upgrade They will not contain the omega 3s which their wild cousins posses. Plus, the tight swimming environment is a fine habitat for viruses or parasites. The local directors struggle with these and similar problems. Their main weapons are anti-bodies or pesticides.
The FDA is aware of these issues and believes that two servings of seafood weekly should be the maximum. Other experts think that is still too much. There are many differences that makes this problem tough to pin down.
As an example, Alaskan salmon is frequently described as clean and possibly off the shoreline of Alaska it is. Nevertheless, salmon are serious travelers. They are born in fresh water, swim all over the Pacific ocean and return home to spawn in fresh water. They can acquire as many pollutants as any that originated off the Southern California coast.
Superior fish oil companies have two methods to solve the problem. The most obvious one is this. Simply get the oil from fish that live in a clean habitat their whole lifespan. On a personal note, I also prefer to use an omega 3 rich species that is not in danger. For these reasons, my choice is hoki. It is a very plentiful fish that is native to the Southern ocean southwest of New Zealand. Look at the map. The whole area is one of the less travelled and least industrialized places on earth.
Next, ensure that the supplement is molecularly distilled. This process is very effective it they know what they are doing. However, it may not remove everything - especially chemicals that are added after the catch. A good company solves this problem by not using any chemicals to begin with.
In conclusion, for those of you who wish to keep eating fish, remember that it is cold water fatty fish that give you the most benefits. It is still a good idea to have an omega 3 supplement to fill in the gaps. Omega 3s only stay in the blood for 2-3 days. Consistent doses will allow the body to use them efficiently.
