Fish derived polyunsaturated fatty acids and their health effects: the influence of mercury

Abstracts

EN

Fatty acids derived from fish and fish oils have a strong beneficial effect on cardiovascular health and neurodevelopment. Dietary omega 3 fatty acids prevent cardiovascular disease development by the influence on eicosanoid synthesis, cytokine and growth factors production, lipid and lipoprotein metabolism, endothelial relaxation. They have a strong antiarrhytmic action on the heart. Enhanced consumption of fish derived fatty acids is related to the low incidence of cardiovascular events and sudden cardiac deaths. High content of mercury in some fishes may attenuate the beneficial effects of omega 3 fatty acids on cardiovascular health and also on neurodevelopment of newborns and children

Przeszło 30 lat temu zaobserwowano, iż Eskimosi, których dieta opiera się na tłustych rybach morskich, rzadko chorują na choroby układu krążenia takie jak choroba niedokrwienna serca, zawał mięśnia sercowego. Obserwacje te dały początek licznym badaniom epidemiologicznym, klinicznym i doświadczalnym mającym na celu wyjaśnienie tego zjawiska. Obecnie nie ulega wątpliwości, iż ryby będące źródłem niezbędnych nienasyconych kwasów tłuszczowych z grupy n-3 (n-3 PUFA) są ważnym składnikiem pożywienia, gdyż zawarte w nich kwasy tłuszczowe istotnie wpływają na szereg przemian metabolicznych i tym samym na ryzyko rozwoju różnych chorób.
