Canola oil helps control blood sugar in type-2 diabetics

A common kitchen staple, canola oil, could help control blood sugar in people with type 2 diabetes, according to researchers at the University of Toronto.

Results of the study were presented at the American Diabetes Association Scientific Sessions in June, and they suggest that adding canola oil to the diet is an easy way to not only prevent blood sugar spikes, but also cardiovascular disease.

The study

Researchers gave 141 participants with type 2 diabetes either a test or control diet for three months. The test diet was lower in carbohydrates, higher in fat and included bread made with canola oil. On average, the people in the test diet group ate about 31 grams of oil per day. Participants in the control diet ate low-fat and high-fiber foods, with an emphasis on whole wheat.

Results showed that those in the test group had better blood glucose control and, more importantly, those who had the most risk for adverse effects from type 2 diabetes benefited the most from the diet.

"This study shows the advantage of using canola oil in type 2 diabetes to improve both blood cholesterol and blood glucose control by reducing the glycemic load (GI multiplied by the amount of carbohydrate in the diet), especially in those at highest risk of diabetes complications," lead researcher David J.A. Jenkins, M.D., said in a press release.

Cholesterol benefits

While the study participants already had low "bad" LD cholesterol levels, eating canola oil was associated with an even further reduction of this type of cholesterol, the researchers noted.

"The ability of canola oil to help control blood glucose in people with type 2 diabetes adds to existing evidence of several health benefits, including [cardiovascular disease] risk reduction," added Shaunda Durance-Tod, M.Sc., R.D., CanolaInfo manager, Canola Council of Canada. "Further studies are now warranted on the effect of canola oil in a Mediterranean-type diet on glycemic control, blood fats and weight loss in type 2 diabetes."

Results of the study are published in the journal Diabetes Care.
