What specific long-chain polyunsaturated fatty acids are abundant in recognized healthy oily fish like salmon and mackerel?
Answer
Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)
Fish widely recognized for supporting long-term health, such as salmon, mackerel, herring, and sardines, derive their benefits from high concentrations of Omega-3 fatty acids, specifically Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These are essential nutrients that the human body cannot synthesize efficiently on its own. EPA and DHA are strongly correlated with positive outcomes like managing triglycerides, maintaining heart rhythm, and supporting brain structure. This contrasts sharply with oilfish, where the dominant fat—wax esters—offers acute digestive risks rather than these predictable, long-term wellness advantages.
