Effects of monounsaturated oils on serum lipid profile which one is better?

ABSTRACT

To compare the effects of two dietary monounsaturated oils on plasma lipid profile in Albino rats, thirty-six Albino rats were divided into three groups. Each group was fed a diet containing a different dietary oil for 12 weeks Lipid profiles of control, rapeseed oil group and olive oil group at 0-week and 12 weeks were estimated. Results showed that in olive oil group, there was a non-significant [P>0.05] decrease of 3.8% in TC, significant [P<0.005] decrease of 12% in LDL-c, 18% in VLDL-c 17% in TAG, 8.5% decrease in it levels. There was a significant increase of 21% in HDL-c levels. In Rapeseed oil group, there was a non-significant decrease of 26% in VLDL-c, 3.6%, in TAG, 1.8% in TL levels; there was a significant increase of 11.6% in TC, 20.8% in LDL-c 14.3% in HDL-c levels. We conclude that not all monounsaturated oils have the same effects on serum lipid profile. In this study, olive oil diet corrected the lipid profile mere beneficially as compared with the rapeseed oil
