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 .
Rice bran oil and canola oil improve blood lipids compared to sunflower oil in women with type 2 diabetes: A randomized, single-blind, controlled trial.
BACKGROUND Hypolipidemic effects of vegetable oils have been demonstrated in a number of studies , but there is no study , which compares the effects of canola oil ( CO ) and rice bran oil ( RBO ) on diabetic patient . We aim ed to compare the effects of CO and RBO consumption on blood lipids in women with type 2 diabetes . METHODS Seventy-five postmenopausal women with type 2 diabetes participated in this single-center , r and omized , controlled , parallel-group trial in Shiraz , Iran . Participants were r and omly allocated to three groups including a control group ( balance diet + 30 g/d sunflower oil ) and two intervention groups ( balance diet + 30 g/day CO or RBO ) . At baseline and after 8 weeks , serum total cholesterol ( TC ) , triglyceride ( TG ) , low-density lipoprotein cholesterol ( LDL-C ) , and high-density lipoprotein cholesterol ( HDL-C ) were measured . RESULTS At 8 weeks , mean of serum levels of TG ( mg/dL ) , TC ( mg/dL ) , and LDL-C ( mg/dL ) significantly decreased in the CO group ( -23.66 , P < .001 ; -11.92 , P < .001 ; and -6.33 , P = .013 , respectively ) and RBO group ( -38.62 , P < .001 ; -17.25 , P < .001 ; and -8.90 , P = .002 , respectively ) compared with the controls ( 7.01 , 4.06 , and 2.90 , respectively ) . Also , in comparison with CO group , the changes of TG , LDL-C , and non-HDL-C levels were significantly more in the RBO group ( P = .007 , P = .012 , and P = .011 , respectively ) . Levels of serum HDL-C remained unchanged in all groups at the end of study . CONCLUSIONS Substitution of RBO or CO for sunflower oil could attenuate lipid disorders in type 2 diabetes women . Moreover , RBO could improve lipid profile more efficiently than CO
