There were no significant effects on Apo lipoprotein A1 and Apo lipoprotein B. Conclusion : This meta- analysis suggested that OO consumption decreased serum TC , LDL-c , and TG less but increased HDL-c more than other plant oils
ABSTRACT Objective : We aim to report a systematic review and meta- analysis of r and omized controlled trials ( RCTs ) on effects of olive oil consumption compared with other plant oils on blood lipids .
Comparison of an oleic acid enriched-diet vs NCEP-I diet on LDL susceptibility to oxidative modifications
Objective : The objective of this trial was to compare the effect on the susceptibility of plasma Low Density Lipoprotein ( LDL ) to oxidative modifications of consumption of two oleic rich diets , prepared with two different plant oils , virgin olive oil (OL)1 and refined high monounsaturated fatty acids ( MUFA sunflower oil ( SU ) ) , with the susceptibility of plasma LDL to oxidation after an National Cholesterol Education Program step 1 ( NCEP-I ) phase diet . Design : A r and omized crossover design .Subjects and interventions : Twenty-two healthy normolipidemic young males consumed an NCEP-I diet for a 4-week period . Subjects were then assigned to two diets each of 4-weeks duration . Group one was placed on an olive oil enriched diet ( 40 % fat , 22 % MUFA ) followed by a 4-week period of a MUFA diet enriched in sunflower oil ( 40 % fat , 22 % MUFA ) . In group two , the order of the diets was reversed . Results : Both MUFA diets induced a decrease in saturated ( 14:0 , 16:0 , and 18:0 ) and an increase in monounsaturated and polyunsaturated n-6 ( 18:2 , 20:3 , and 20:5 ) plasma LDL-phospholipid fatty acids , compared to the NCEP-I diet ( P<0.01 ) . No significant differences in lag times were observed between the olive oil and the NCEP-I diet periods . However there was a greater inhibition time ( P<0.001 ) when subjects consumed the MUFA rich sunflower oil diet compared to the NCEP-I diet . These differences were probably related to the relative enrichment of plasma LDL particles in α-tocopherol due to the high vitamin E content of the MUFA-rich sunflower oil . Indeed , the α-tocopherol content was positively correlated with lag time ( r=0.338 ; P<0.008 ) . Conclusion : Our findings suggest that changes in plasma LDL α-tocopherol content with practical solid-food diets can decrease its susceptibility to oxidation .
