Canola oil could ‘benefit type 2 diabetes patients’

16 June 2014

Canola oil - also known as rapeseed oil - can be beneficial to those with type 2 diabetes, as it reduce blood sugar levels and low-density lipoprotein (LDL) cholesterol, according to a new study from St. Michael's Hospital.

The research team compared people with the condition who ate a low glycemic index diet that included bread made with canola oil with those who consumed a whole wheat diet known to reduce the risk of cardiovascular disease.

According to Dr David Jenkins, lead author of the study, the diet that included canola bread has the most impact on people with the highest levels of blood glucose.

He added that the canola bread had caused a reduction of LDL - also known as “bad” cholesterol - in participants, which had subsequently led to a seven per cent decrease in cardiovascular events.

Dr Jenkins said those on the whole wheat diet had better blood flow after 12 weeks compared to those on the canola bread equivalent, but he is unsure what the significance of this finding is. 

He developed the idea of the glycemic index in the early 1980s as a way to explain how different carbohydrates affected blood glucose and to discover which foods are best for people with diabetes.
