Extra Virgin Olive Oil Polyphenols Promote Cholesterol Efflux and Improve HDL Functionality

EVOO-PC enrichment decreases the oxidizability of lipoproteins. Plasma was incubated with EVOO or EVOO-PC prior to isolating HDL and LDL. HDL and LDL pretreated with EVOO or EVOO-PC as well as untreated controls were oxidized by incubation with copper ions for 4 h. The resistance to lipid peroxidation and the oxidizability of HDL and LDL were monitored by determining the lag phase (a, b, d, e) and by measuring conjugated diene formation (), respectively (c, f). Results are expressed as the means ± SEM of three independent experiments. , , and .
