Timely findings’: Canola oil offers blood sugar management potential for diabetics

Posted:  Thursday, June 19, 2014

Blood sugar levels and heart health can be improved and maintained if canola oil rich in Alpha-Linoleic acid, in accordance with a low glycaemic diet is consumed a new study from Canada has suggested.

A report published finding by Diabetes Care which has stated that individuals who consumed a low glycaemic load diet combined with canola oil enriched bread supplement as opposed to individuals who consumed whole grain diet with whole wheat bread supplement had shown significantly lower blood sugar levels; the study was conducted through a parallel design, randomized trial that studied haemoglobin A1c (HbA1c), a marker of long-term presence of excess glucose in the blood

“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 glycaemic load (GI multiplied by the amount of carbohydrate in the diet), especially in those at highest risk of diabetes complications,” said lead researcher Professor David Jenkins from the University of Toronto.

He added, “These findings are timely since diabetes is expected to double in the next 20 years and means of preventing it and its complications are major concerns of governments and the general public.”

Canola Council of Canada were satisfied with the results of the study, which was sponsored by them along with the Government of Canada. Canolainfo manager Shaunda Durance –Tod, MSc, and R.D Canola Council of Canada said, “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 CVD risk reduction.” She added, “Further studies are now warranted on the effect of canola oil in a Mediterranean-type diet on glycaemic control, blood fats and weight loss in type-2 diabetes.”

Hence, determining that a low glycaemic diet along with a canola oil supplement is helpful to maintain and manage blood sugar levels.

Study details

Canadian scientist prepared a blood sugar chart by recruiting and studying 141 type-2 diabetes patients who were administered oral anti hyperglycaemic agents. One group was given a low glycaemic diet and the others were given a whole grain diet or supplement.

The normal range of blood sugar levels in type 2 diabetes is between 4 to 7 mmol/L before the consumption of sugar and post prandial i.e. after consuming sugar needs to be under 8.5 mmol/L; whereas the for a non-diabetic individual is under 4 mmol/L. A diabetic individual has to try and maintain a normal level as to maintain normal function of the body. The research showed a significant difference in the levels of the individuals that consumed a low glycaemic diet.

Participants who had a combination diet were the one who benefitted with the most to control blood sugar levels and well reduce the risk of cardiovascular diseases. The research concluded, “By contrast, whole-grain cereals appear to improve vascular reactivity, possibly helping to explain their benefit in CVD risk reduction.”
