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 .
Plasma lipid effects of three common vegetable oils in reduced-fat diets of free-living adults.
We compared plasma lipid changes due to the polyunsaturated fatty acids ( PUFAs ) in partially hydrogenated soybean oil , corn oil , and sunflower oil fed in reduced-fat diets ( 22 - 26 % of total energy ) . Each oil was the dominant fat in isoenergetic diets of central ly prepared foods consumed by 26 male and 35 female normolipidemic , free-living individuals . Test diets were consumed double-blind , alternating with self-selected diets for 5 wk each . The ranges of proportions of total fat were : 4.7 - 9.7 % polyunsaturated fat , 8.9 - 14.2 % monounsaturated fat and 5.4 - 7.4 % saturated fat . All three diets lowered ( P < 0.0001 ) total cholesterol ( 11 % ) , LDL cholesterol ( 13 % ) , and HDL cholesterol ( 10 % ) , without triglyceride changes . We conclude that PUFAs at approximately 6 % of total energy result in clinical ly relevant plasma cholesterol-lowering and that the proportion of polyunsaturated fat must be an important consideration when planning reduced-fat , reduced-saturated-fat diets
