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 .
Balance of unsaturated fatty acids is important to a cholesterol-lowering diet: comparison of mid-oleic sunflower oil and olive oil on cardiovascular disease risk factors.
OBJECTIVE To evaluate the effects of a trans fat-free monounsaturated fatty acid-rich vegetable oil ( NuSun sunflower oil , National Sunflower Association , Bismark , ND ) that is a good source of polyunsaturated fatty acids ( PUFA ) and low in saturated fatty acids on lipid and lipoprotein levels and oxidative stress . DESIGN A double-blinded , r and omized , three period crossover , controlled feeding study . SUBJECTS/ SETTING Thirty-one men ( n=12 ) and women ( n=19 ) with moderate hypercholesterolemia who were 25 to 64 years of age . INTERVENTION Experimental diets provided 30 % fat ( olive oil or NuSun sunflower oil contributed one half of the total fat ) , 8.3 % vs 7.9 % saturated fatty acid , 17.2 % vs 14.2 % monounsaturated fatty acid , and 4.3 % vs. 7.7 % PUFA ( olive oil and NuSun sunflower oil , respectively ) , and 294 mg cholesterol . The control diet was an average American diet ( 34 % fat , 11.2 % saturated fatty acid , 14.9 % monounsaturated fatty acid , 7.8 % PUFA ) . Subjects consumed each diet for 4 weeks with a 2-week compliance break before crossing over to another diet . MAIN OUTCOME MEASURES Lipid and lipoprotein levels were measured , and measures of oxidative stress , including lag time , rate of oxidation , total dienes , and lipid hydroperoxides , were assessed . STATISTICAL ANALYSIS The mixed model procedure was used to test for main effects of diet , feeding period , and order of diets . Tukey-Kramer adjusted P values were used to determine diet effects . RESULTS The NuSun sunflower oil diet decreased both total and low-density lipoprotein cholesterol levels compared with the average American diet and the olive oil diet . There was no effect of the olive oil diet compared with the average American diet . Total cholesterol decreased 4.7 % and low-density lipoprotein cholesterol decreased 5.8 % on the NuSun sunflower oil diet vs the average American diet . There was no effect of the experimental diets on triglyceride levels , rate of oxidation , total dienes , lipid hydroperoxides , or alpha-tocopherol . Lag time was the longest following the olive oil diet and shortest following the NuSun sunflower oil diet . CONCLUSIONS The higher PUFA content appeared to account for the greater total and low-density lipoprotein cholesterol lowering and reduction in lag time of the NuSun sunflower oil diet . However , the fact that there were no differences in the result ing oxidation products suggests there were no adverse effects on low-density lipoprotein oxidation . Since PUFAs are important for cholesterol lowering , foods that replace saturated fatty acids should include a balance of unsaturated fatty acids
