These results provide evidence that olive oil might exert beneficial effects on endothelial function as well as markers of inflammation and endothelial function , thus representing a key ingredient contributing to the cardiovascular-protective effects of a Mediterranean diet .
The aim of the present systematic review was to synthesize data from r and omized controlled trials investigating the effects of olive oil on markers of inflammation or endothelial function .
Krill oil supplementation increases plasma concentrations of eicosapentaenoic and docosahexaenoic acids in overweight and obese men and women.
Anta rct ic krill , also known as Euphausia superba , is a marine crustacean rich in both eicosapentaenoic acid ( EPA ) and docosahexaenoic acid ( DHA ) . We tested the hypothesis that krill oil would increase plasma concentrations of EPA and DHA without adversely affecting indicators of safety , tolerability , or selected metabolic parameters . In this r and omized , double-blind parallel arm trial , overweight and obese men and women ( N = 76 ) were r and omly assigned to receive double-blind capsules containing 2 g/d of krill oil , menhaden oil , or control ( olive ) oil for 4 weeks . Results showed that plasma EPA and DHA concentrations increased significantly more ( P < .001 ) in the krill oil ( 178.4 + /- 38.7 and 90.2 + /- 40.3 micromol/L , respectively ) and menhaden oil ( 131.8 + /- 28.0 and 149.9 + /- 30.4 micromol/L , respectively ) groups than in the control group ( 2.9 + /- 13.8 and -1.1 + /- 32.4 micromol/L , respectively ) . Systolic blood pressure declined significantly more ( P < .05 ) in the menhaden oil ( -2.2 + /- 2.0 mm Hg ) group than in the control group ( 3.3 + /- 1.5 mm Hg ) , and the response in the krill oil group ( -0.8 + /- 1.4 mm Hg ) did not differ from the other 2 treatments . Blood urea nitrogen declined in the krill oil group as compared with the menhaden oil group ( P < .006 ) . No significant differences for other safety variables were noted , including adverse events . In conclusion , 4 weeks of krill oil supplementation increased plasma EPA and DHA and was well tolerated , with no indication of adverse effects on safety parameters
