Canola oil may be best for type 2 diabetics

There has been a surge in cases of type 2 diabetes linked to the obesity epidemic. Lifestyle considerations dealing with good nutrition, exercise, and adequate rest are essential in dealing properly with this condition. Recent research shows that canola oil may be particularly helpful for people suffering from type 2 diabetes.

Researchers have found that a canola oil enriched low-glycemic-load diet improved glycemic control in type 2 diabetes reported Diabetes Care. This finding proved to be particularly true in participants with raised systolic blood pressure. In this study whole grains were observed to improve vascular reactivity.

Canola oil should be a top choice for people with type 2 diabetes

Research has suggested there are benefits from canola oil for people with type 2 diabetes reports St. Michael's Hospital in a review of this study. These researchers are taking the position that canola oil should be one of the oils of top choice for people suffering from type 2 diabetes.

Dr. David Jenkins, head of the hospital’s Clinical Nutrition and Risk Factor Modification Centre, did a comparison of people suffering from type 2 diabetes who ate either a low glycemic index diet which included bread made with canola oil, or a whole wheat diet which is known to reduce the risk of cardiovascular disease. In this study it was observed that people on the canola bread diet experienced both a decrease in blood glucose levels and a significant decrease in LDL, or bad, cholesterol.

Canola helps the people who need the most help

It was particularly exciting for the researchers to find that the canola bread diet appeared to have the most significant impact on people who were most in need of help. These people had the highest HbA1c tests measuring blood glucose over the previous two or three months. Dr. Jenkins is a professor of both nutritional sciences and medicine at the University of Toronto. He said the decrease in LDL cholesterol which was observed in his study of 141 people could translate into a 7 per cent decrease in cardiovascular events.

Canola comes from a contraction of the words Canada and ola


Canola comes from a contraction of the words Canada and ola, meaning oil. Canola was first developed from rapeseed at the University of Manitoba in the 1970s. There is only 7 percent saturated fat in canola, which is less than half that of olive oil. Olive oil has long been recognized for its health benefits.

Another interesting finding was that patients on the whole wheat diet appeared to have better blood flow after 12 weeks than those on the canola bread diet. This was measured by the EndoPat test which uses a cuff on the arm which is similar to a blood pressure test. This positive result appears to be an indication of why whole wheat foods have consistently been shown to lower the risk of cardiovascular disease.

The concept of the glycemic index was developed by Dr. Jenkins and his colleagues in the early 1980s. The glycemic index is a way of explaining how different carbohydrates affect blood glucose. This helps with determining which foods are best for people with diabetes. High glycemic index
produces a large increase in blood glucose and insulin, which often damages eyes, kidneys and
heart. High glycemic foods include:

1: White bread

2: Most breakfast cereals

3: Potatoes

4: Rice

The carbohydrates in low glycemic index foods are broken down more slowly so that people get more gentle increases in blood glucose and insulin and so they get less tissue damage to eyes and kidneys, and other organs.

This study offers new hope for people suffering from type 2 diabetes. The findings of the dramatic benefits of canola oil for this condition should be taken seriously. Other studies have also shown that low glycemic index diets are associated with a decrease in both diabetes and cardiovascular events.

It is advisable to take good nutritional advice for both prevention and treatment of these conditions. It can always help to discuss your nutritional needs with your Family doctor. Family doctors are well
trained to understand these essential points about the association of nutrition and good health.



Note that there is no mention of any tests to determine whether the canola oil or the low-GI diet is responsible for the improvement.
Iam dietetic i use olive oil is canalo oil better ?
