Despite limitations in these data , our NMA findings are in line with existing evidence on the metabolic effects of fat and support current recommendations to replace high saturated-fat food with unsaturated oils
The aim of this network meta- analysis ( NMA ) is to compare the effects of different oils/solid fats on blood lipids .
Small Dense Low-Density Lipoprotein Concentration and Oxidative Susceptibility Changes after Consumption of Soybean Oil, Rice Bran Oil, Palm Oil and Mixed Rice Bran/Palm Oil in Hypercholesterolaemic Women
The effects of a diet containing soybean oil ( SBO ) , rice bran oil ( RBO ) , palm oil ( PO ) or a RBO/PO ( 3:1 ) mixture on the composition and oxidation of small dense low-density lipoproteins ( sdLDL ) in 16 hypercholesterolaemic women were investigated . During the 8-week control period , participants consumed a free-choice weight-maintaining diet comprising carbohydrate ( 55 % energy ) , protein ( 15 % energy ) and fat ( 30 % energy ) with < 300 mg/day of cholesterol . During each 10-week study period , participants consumed this same diet but with the addition of one of the three test oils or the RBO/PO mixture .  Total cholesterol and low-density lipoprotein (LDL)-cholesterol levels were significantly reduced during SBO , RBO and RBO/PO consumption , while high-density lipoprotein cholesterol was significantly decreased by SBO consumption . There was a significant reduction in sdLDL-cholesterol levels only after using SBO and it tended to be reduced during RBO/PO consumption , whereas it was significantly increased following PO consumption . The sdLDL oxidation lag time was significantly increased during PO , RBO/PO and RBO consumption , but significantly reduced following SBO . The results for the RBO/PO mixture suggest that this oil mixture might further reduce the risk of atherosclerosis
