Fish Oil - Possible Benefits and Possible Consequences
Fish oil seems to be the new cod liver oil (which, incidentally, is type of fish oil) - a relative cure-all. But do you need to take it? Why should you take it? First and foremost, realize that for the most part it is better to get the nutrients that you need by eating a healthy and well-rounded diet. It is better to eat fish than to take a fish oil supplement.
Of course, this is not always completely reasonable - you may not want to eat fish every single day. Another thing to consider is the fact that some fish may contain mercury, and this is not good for humans, especially pregnant women. Also, realize that fattier fishes like salmon have a higher percentage of omega-3 fatty acids than other fish, like canned tuna.
That being said, let’s find out why other people take fish oil:
Fish oil is full of omega-3 fatty acids. Yes, the word “fatty” may throw you off, but omega-3 fatty acids are actually very good for your heart. That is why many people take fish oil as a preventative measure against heart disease. People who have a history of heart attacks in their family are likely to want to take fish oil as a supplement.
In fact, fish oil is a great supplement for anyone who already has coronary artery disease (even those who have not yet had a heart attack).
People who have auto-immune disorders like rheumatoid arthritis and psoriasis should also consider taking a fish oil supplement on days that they do not eat fish. About 3 grams of omega-3s a day are recommended. Clinical studies suggest that fish oil can help with joint pain and swelling of rheumatoid arthritis. Omega-3s can suppress the immune response.
People who have high triglycerides may also benefit from fish oil, as well.
