The Scientific literature does not show a clear effect of a diet rich in palm oil on the plasma content of lipoproteins, triglycerides and cholesterol, some of the reports are in disagreement. The aim of this work was to study the effect of palm oil on triglycerides and cholesterol content on plasma in lipoproteins and fatty acid composition in plasma lipids. The experiment was carreid out in New Zealand male rabbits, fed with a diet 10% (wt/wt) fat content during 9 weeks. The fats used were corn oil (control group) or palm iol (experimental group). The animals were anaesthetized after 12 hour of starvation, fatty acid composition on triglycerides, cholesterol plasmatic and lipoproteins levels were determined. The animals fed with palm oil showed a not significant increase in very low density lipoprotein (VLDL) and plasma triglycerides and cholesterol. Palm oil diet showed high relation of satured/poliinsatured fatty acids and increased the contend of palmitic acid in plasma triglycerides with reduction of linoleic acids in this lipids fraction; However, the cholesteryl ester fatty acids did not change between corn oil and palm oil diet. The non significant increase in plasma triglycerides and VLDL content of the palm oil group must be taken into account in the dietetic control of type IV hiperlipidemic patient.
