Ahh, fish oils, the never ending debate on how much and how to consume them. Here's the skinny: fish oils come from fatty fish. Yes, specifically the tissue of fatty fish such as trout, mackerel, tuna, herring, sardines and salmons. Nutritionists often favor fish oils because of two main ingredients: DHA and EPA, which are two types of Omeda-3 fatty acids. The fillets alone of oily fish contain 30% oil. White fish only contains high concentrations of oil in the liver and have much less oil. Oily fish are also good sources of vitamins A and D.
