Changes in serum lipid profile of albino Rats fed on Canola Oil supplemented with atherogenic elements: 18 weeks study

Abstract

Amongst lipid lowering factors, the dietary intervention for treating hyperlipidaemia and atherosclerosis associated ailments is physiological and gratifying. Canola is rich in monounsaturated fatty acids and is locally cultivated and cost effective. The criterion of the study was to determine the status of serum lipid profile in albino rats fed on canola oil diets for prolonged period of 24-weeks and to compare the same with those fed on canola oil supplemented with atherogenic elements. Results demonstrate that moderate amounts of canola oil (2.9% in diet) has triglyceride and cholesterol lowering effects. Both moderate and high amounts of canola oil (20%) decrease serum LDL-c profiles and resist lowering of HDL-c levels in rats fed with canola oil alongwith atherogenic elements. Conclusions: These findings reveal canola oil amongst the important supplement of monounsaturated fatty acids in animals and these findings may be generalized for humans.
