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 .
In vivo nutrigenomic effects of virgin olive oil polyphenols within the frame of the Mediterranean diet: a randomized controlled trial.
The aim of the study was to assess whether benefits associated with the traditional Mediterranean diet ( TMD ) and virgin olive oil ( VOO ) consumption could be mediated through changes in the expression of atherosclerosis-related genes . A r and omized , parallel , controlled clinical trial in healthy volunteers ( n=90 ) aged 20 to 50 yr was performed . Three-month intervention groups were as follows : 1 ) TMD with VOO ( TMD+VOO ) , 2 ) TMD with washed virgin olive oil ( TMD+WOO ) , and 3 ) control with participants ' habitual diet . WOO was similar to VOO , but with a lower polyphenol content ( 55 vs. 328 mg/kg , respectively ) . TMD consumption decreased plasma oxidative and inflammatory status and the gene expression related with both inflammation [ INF-gamma ( INFgamma ) , Rho GTPase-activating protein15 ( ARHGAP15 ) , and interleukin-7 receptor ( IL7R ) ] and oxidative stress [ adrenergic beta(2)-receptor ( ADRB2 ) and polymerase ( DNA-directed ) kappa ( POLK ) ] in peripheral blood mononuclear cells . All effects , with the exception of the decrease in POLK expression , were particularly observed when VOO , rich in polyphenols , was present in the TMD dietary pattern . Our results indicate a significant role of olive oil polyphenols in the down-regulation of proatherogenic genes in the context of a TMD . In addition , the benefits associated with a TMD and olive oil polyphenol consumption on cardiovascular risk can be mediated through nutrigenomic effects
