摘要：The effects of dietary palm and corn oil levels on plasma lipoprotein profile were investigated in albino rats Four week-old Wistar rats (n=8 per group) were maintained (for 28 days) on standard rat food supplemented (10, 20 and 30% by weight) with red palm oil (RPO), refined palm olein (REFPO) and corn oil (CO). Rats fed the experimental diets exhibited a direct dose-effect relationship between levels of dietary fat and total cholesterol (TC) concentrations. At each level of dietary intake , the cholesterolemia effects of corn oil-based diets were less than those of palm oil (red or refined), while the cholesterolemia effects of REFPO-based diets were intermediate between those of RPO and CO-based diets. The groups fed 30% oil supplemented diets had significantly lower (P cardiovascular disease by raising plasma non-HDL-C concentrations and lowering plasma HDL-C concentrations.
