A diet rich in monounsaturated rapeseed oil reduces the lipoprotein cholesterol concentration and increases the relative content of n-3 fatty acids in serum in hyperlipidemic subjects.
The effects of 3 wk on a diet rich in monounsaturated rapeseed oil were compared with those of a diet containing sunflower oil within a lipid-lowering diet. Ninety-five subjects with moderate hyperlipoproteinemia were randomly assigned to one of the two well-controlled diets prepared at the hospital kitchen. Total serum, low-density- and high-density-lipoprotein cholesterol concentrations decreased by 15%, 16%, and 11% (P < 0.001), respectively, on the rapeseed oil diet and by 16%, 14%, and 13% (P < 0.001) on the sunflower oil diet. Serum triglycerides decreased more markedly (by 29%, P < 0.001) on the sunflower oil than on the rapeseed oil diet (14%, P < 0.01). The n-3 fatty acids (20:5 and 22:5) in the serum phospholipids increased significantly on the rapeseed oil diet but decreased on the sunflower oil diet. There was an increase in the alpha-tocopherol concentrations after both diets. The findings indicate that low erucic acid rapeseed oil can replace oils and fats rich in polyunsaturated fatty acids in a lipid-lowering diet.
