Are there other nutritional advantages to eating fish rather than taking Omega 3 supplements?

Research has shown that obtaining Omega 3 fatty acids from food sources may be a better choice than using supplements. While concentrated fish oil capsules may be a good way of obtaining isolated Omega 3s, that refining process can eliminate other necessary nutrients that are present in whole fish, such as calcium, Vitamin D, and the antioxidant selenium. Research has also shown that the absorption of Omega 3s, as well as the blood pressure regulating properties of Omega 3s, are much improved when they are consumed in whole fish. This is due to the presence of these additional nutrients, proteins and co-factors. Additionally, studies have linked long term use of fish oil supplements with various fatty liver disease conditions.
