Omega-3 Fish Oils: Omega-3 Content of Oily Fish Like Mackerel, Salmon, Sardines, EPA, DHA
Fresh oily fish is one of the best and most convenient sources of omega-3 essential fatty acids. It is the one major exception to the need to restrict dietary fat intake for optimum health and weight loss. Unlike other foods rich in omega-3 essential fatty acids, like flax or linseed oil, fresh fish is freely available. And unlike nuts and seeds – the other main food source of omega-3, oily fish is a much richer source.
The omega-3 essential fatty acids in oily fish are called:
- Eicosapentaenoic acid (EPA) and,
- Docosahexaenoic acid (DHA)
See Fig 1. for the content of omega-3 (EPA and DHA) in fresh fish.
