Anyone NOT taking fish oil supplements in nuts!* Eating fish is GREAT, and should be the foundation of a healthy diet, but ALL fish contains some level of mercury (and other bad stuff.) Fish oil supplements are purified. I have NEVER seen any study even hinting at any downside of fish oil supplements.
I've never had any squeaky fish, therefore I've never felt obligated to oil them. However, I do love the occasional can of sardines.

What about the fishy tasting burps after you take the supplements?
I believe that some fish oils are not very pure at all. Look for "molecularly distilled" on the label. Barry Sears discusses qualities of fish oils in his book "The Omega 3 Zone," a follow up to his other Zone Diet books.
I take Carlson's lemon flavored cod liver oil, very pure and rich in omega 3's plus, of course, Vitamin D, not available in "fish oil." I need Vitamin D year round because I live so far north, sunshine rarely touches my skin. Some experts believe that SAD (seasonal affective disorder AKA feeling gloomy and depressed all winter) can be alleviated by Vitamin D, and in fact, lack thereof may well cause or at least contribute to SAD.
Small fish, like salmon and sardines, have very little mercury, I have read.
