Canola oil may help manage type 2 diabetes, says a new study from Canada.

Canola, that is a combination of two words Canada and “ola” that means oil, is derived from rapeseeds. The oil that was first developed in the 1970s by the University of Manitoba in Canada soon caught the public attention for its health properties.  According to the researchers, canola oil is very low in saturated fat (seven percent) and does not contain even half levels of saturated fats found in olive oil.

During the study, 141 type 2 diabetic patients received either a low glycemic (GI) index diet based mainly on bread made with canola oil or a whole wheat diet.

Results showed that the diet based on canola oil helped bring down blood glucose levels and bad cholesterol.  Interestingly, people with higher blood glucose levels benefitted the most, according to Dr. David Jenkins from St. Michael’s Hospital in Toronto and colleagues.

Dr. Jenkins said that the reduction in bad cholesterol was equal to achieving a seven percent decrease in cardiovascular events or gave the effect of taking a double dose of cholesterol lowering drugs statins.  On the other hand, taking the whole wheat diet improved blood flow in patients.

“A canola oil–enriched low-GL diet improved glycemic control in type 2 diabetes, particularly in participants with raised SBP, whereas whole grains improved vascular reactivity,” the authors, while concluding their study wrote.

The study has been published in the journal Diabetes Care, Saturday, 14 June.
