Omega-3 mastné kyseliny a kardiovaskulární onemocnění

MUDr. Michal Vrablík Ph.D
III. interní klinika VFN a 1. LF UK, Praha

Omega-3 polynenasycené mastné kyseliny a jejich účinky nejen na kardiovaskulární systém přitahují pozornost odborné i laické veřejnosti již řadu let. Výsledkem jsou tisíce článků a řada monografií, které se zabývají především vlivem konzumace omega-3 mastných kyselin rybího (v menší míře i rostlinného) původu na kardiovaskulární systém. Zvýšení konzumace rybích olejů či doplňků s obsahem eikosapentaenové (EPA) a dokosahexaenové (DHA) kyseliny jsou součástí většiny odborných doporučení pro prevenci kardiovaskulárních příhod. Přes množství dat z laboratorních, experimentálních i klinických studií přetrvává řada otázek. Jaký typ a forma omega-3 mastných kyselin je z hlediska kardiovaskulárního systému nejvhodnější? Jaká je vhodná denní dávka? Který z mnoha mechanizmů účinku rybích olejů je nejdůležitější při snižování rizika cévních příhod? Jaká je tolerance potravinových doplňků s obsahem rybích olejů? Na některé z mnoha otázek se pokusíme najít odpovědi v následujícím textu.

Keywords: omega-3 mastné kyseliny, rybí olej, kardiovaskulární onemocnění, eikosapentaenová kyselina, dokosahexaenová kyselina
