Amazing facts – Fish oils (oily fish) come from fatty fish, specifically the tissue of fatty fish, such as trout, mackerel, tuna, herring, sardines, and salmon. Fish oils are of interest to nutritionists and health care professionals because of two main ingredients: DHA (docosahexaenoic acid), and EPA (eicosapentaenoic acid) – both types of Omega-3 fatty acids.
The fillets of oily fish contain up to 30% oil; this figure may vary. White fish, on the other hand, only contain high concentrations of oil in the liver, and have much less oil. Apart from omega-3 fatty acids, oily fish are also good sources of vitamins A and D. Whitefish also contain these nutrients, but at much lower concentrations.
Some people confuse fish oils and cod liver oil – they are different. Fish oils are extracted from the tissue of deep sea oily fish such as tuna, mackerel, herring and salmon. Cod liver oil, by contrast, is extracted solely from the livers of cod. Fish oil contains higher amounts of omega-3 fatty acids than cod liver oil, but lower amounts of vitamins A and D.
