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 .
Controlled evaluation of fat intake in the Mediterranean diet: comparative activities of olive oil and corn oil on plasma lipids and platelets in high-risk patients.
Activities of low-fat diets with olive oil or corn oil on lipids and platelets were studied in 23 middle-aged patients with high atherosclerosis risk for 8 wk . The olive oil diet had a polyunsaturated-saturated ratio of 0.33 vs 1.28 for the corn oil diet .  Plasma total cholesterol was reduced with corn oil , but high-density lipoprotein cholesterol levels were lower with corn oil and unchanged or raised by olive .  Plasma apolipoprotein B levels were equally reduced by both diets ; apolipoprotein AI and the apo AI : B ratio rose only with olive oil .  Plasma-glucose levels were lowered significantly with olive oil . Changes in platelet function were characterized by a reduced sensitivity to arachidonic acid ( particularly with corn oil ) and to collagen ( particularly with olive ) . An olive oil diet with a moderate fat intake ( about 30 % of total calories ) leads to favorable plasma lipoprotein and platelet changes
