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 .
Effect of alpha-linolenic acid-rich Camelina sativa oil on serum fatty acid composition and serum lipids in hypercholesterolemic subjects.
Camelina sativa-derived oil ( camelina oil ) is a good source of alpha-linolenic acid . The proportion of alpha-linolenic acid in serum fatty acids is associated with the risk of cardiovascular diseases . We studied the effects of camelina oil on serum lipids and on the fatty acid composition of total lipids in comparison to rapeseed and olive oils in a parallel , double-blind setting . Sixty-eight hypercholesterolemic subjects aged 28 to 65 years were r and omly assigned after a 2-week pretrial period to 1 of 3 oil groups : camelina oil , olive oil , and rapeseed oil . Subjects consumed daily 30 g ( actual intake , approximately 33 mL ) of test oils for 6 weeks . In the camelina group , the proportion of alpha-linolenic acid in fatty acids of serum lipids was significantly higher ( P < .001 ) compared to the 2 other oil groups at the end of the study : 2.5 times higher compared to the rapeseed oil group and 4 times higher compared to the olive oil group . Respectively the proportions of 2 metabolites of alpha-linolenic acid ( eicosapentaenoic and docosapentaenoic acids ) increased and differed significantly in the camelina group from those in other groups . During the intervention , the serum low-density lipoprotein ( LDL ) cholesterol concentration decreased significantly by 12.2 % in the camelina oil group , 5.4 % in the rapeseed oil group , and 7.7 % in the olive oil group . In conclusion , camelina oil significantly elevated the proportions of alpha-linolenic acid and its metabolites in serum of mildly or moderately hypercholesterolemic subjects .  Camelina oil 's  serum cholesterol-lowering effect was comparable to that of rapeseed and olive oils
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
