Effects Of Dietary Saturated, Mono Unsaturated And PolyUnsaturated Fatty acids On Serum Lipids And Lipoproteins In Human Volunteers

The current study deals with effect of different dietary oils on serum lipid profile in human volunteers. The volunteers selected in the study used to consume only one type of oil i.e., sunflower oil, ground nut oil and palm oil as their major source of dietary oil in their food preparations. Palm oil was chosen as an example of saturated fat (SFA), Ground nut oil as monounsaturated fat (MUFA) and Sunflower oil as polyunsaturated fat (PUFA). Hence the study carried out in the volunteers consuming these oils to know their effect on serum lipid profile i.e., changes in total cholesterol (TC), High density lipoprotein (HDL)-cholesterol, Low density lipoprotein (LDL)-cholesterol, Very low density lipoprotein (VLDL)-cholesterol and Triglycerides (TRI) along with changes in the atherogenic index (TC/HDL-cholesterol). The current study shows significant increase in serum TRI levels of Sunflower oil and Ground nut oil consumers. Effect of palm oil on serum cholesterol was more pronounced and the levels of HDL and LDL cholesterol are inversely proportional to one another. VLDLcholesterol level is significantly decreased by palm oil compared to other oils used in the study. The consumption of sunflower oil and palm oil shows significant increase in TC/HDLcholesterol levels.
