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 .
Lipoprotein concentrations in normolipidemic males consuming oleic acid-rich diets from two different sources: olive oil and oleic acid-rich sunflower oil.
The effects on plasma lipid concentrations of two oleic acid-rich diets , prepared with two different plant oils -- olive oil and sunflower oil high in monounsaturated fatty acids (MUFAs)-- were compared with a National Cholesterol Education Program ( NCEP ) I diet . Twenty-one healthy , normolipidemic , young males consumed an NCEP-I diet ( 30 % of energy as fat ) during a 25-d period . Subjects were then assigned to two 4-wk study periods , according to a r and omized , crossover design . Group one was placed on an olive oil-enriched diet ( 40 % fat , 22 % MUFAs ) , followed by a 4-wk period of a sunflower oil-enriched diet ( 40 % fat , 22 % MUFAs ) . In group two , the order of the diets was reversed . Both MUFA dietary periods result ed in an increase in high-density-lipoprotein ( HDL ) cholesterol ( 7 % for the olive oil diet and 4 % for the sunflower oil diet ) and in apolipoprotein ( apo ) A-I ( 9 % for both ) compared with the NCEP-I diet . Low-density-lipoprotein ( LDL ) cholesterol and apo B concentrations ( x + /- SEM ) were lower ( P < 0.05 ) during the sunflower oil diet ( 2.40 + /- 0.11 mmol/L , 0.85 + /- 0.04 mg/L ) than during the olive oil diet ( 2.64 + /- 0.15 mmol/L , 0.93 + /- 0.05 mg/L ) . No significant differences were observed in these variables between the sunflower oil and NCEP-I ( 2.48 + /- 0.13 mmol/L , 0.89 + /- 0.04 mg/L ) diets . ( ABSTRACT TRUNCATED AT 250 WORDS
