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 .
High-monounsaturated fatty acid diets lower both plasma cholesterol and triacylglycerol concentrations.
BACKGROUND Low-fat diets increase plasma triacylglycerol and decrease HDL-cholesterol concentrations , thereby potentially adversely affecting cardiovascular disease ( CVD ) risk . High-monounsaturated fatty acid ( MUFA ) , cholesterol-lowering diets do not raise triacylglycerol or lower HDL cholesterol , but little is known about how peanut products , a rich source of MUFAs , affect CVD risk . OBJECTIVE The present study compared the CVD risk profile of an Average American diet ( AAD ) with those of 4 cholesterol-lowering diets : an American Heart Association/National Cholesterol Education Program Step II diet and 3 high-MUFA diets [ olive oil ( OO ) , peanut oil ( PO ) , and peanuts and peanut butter ( PPB ) ] . DESIGN A r and omized , double-blind , 5-period crossover study design ( n = 22 ) was used to examine the effects of the diets on serum lipids and lipoproteins  : AAD [ 34 % fat ; 16 % saturated fatty acids ( SFAs ) , 11 % MUFAs ] , Step II ( 25 % fat ; 7 % SFAs , 12 % MUFAs ) , OO ( 34 % fat ; 7 % SFAs , 21 % MUFAs ) , PO ( 34 % fat ; 7 % SFAs , 17 % MUFAs ) , and PPB ( 36 % fat ; 8 % SFAs , 18 % MUFAs ) . RESULTS The high-MUFA diets lowered total cholesterol by 10 % and LDL cholesterol by 14 % . This response was comparable with that observed for the Step II diet . Triacylglycerol concentrations were 13 % lower in subjects consuming the high-MUFA diets and were 11 % higher with the Step II diet than with the AAD . The high-MUFA diets did not lower HDL cholesterol whereas the Step II diet lowered it by 4 % compared with the AAD . The OO , PO , and PPB diets decreased CVD risk by an estimated 25 % , 16 % , and 21 % , respectively , whereas the Step II diet lowered CVD risk by 12 % . CONCLUSION A high-MUFA , cholesterol-lowering diet may be preferable to a low-fat diet because of more favorable effects on the CVD risk profile
