Background: This study compares the effects of canola and rice bran oil consumption on serum malondialdehyde and blood pressure in postmenopausal type 2 diabetic women.

Method: 75 participants were allocated to 3 groups including a control group (taking 30g/day sunflower oil), canola oil (CO) group (taking 30g/day) and rice bran oil (RBO) group (taking 30g/day). Measurements were performed at baseline and after 8 weeks.

Results: Results showed that reduction of MDA level were significantly higher in RBO (p<0.001) and CO (p<0.05) groups compared to the controls. Also, reduction in MDA level were more for RBO group than CO group (p=0.012). Levels of blood pressure remained unchanged in all groups.

Conclusion: Consuming either CO or RBO could decrease the levels of MDA and oxidative stress in diabetic patients, however RBO is more effective than CO. Neither of the oils has any significant impact on blood pressure of diabetic women.
