Olive Oil Diet Reduces Risk of Type 2 Diabetes

Traditionally a low fat diet has been prescribed to prevent various diseases such as heart disease and diabetes. While studies have shown that high fat diets may increase the risk of certain diseases such as cancer and diabetes, it appears that it is the type of fat that counts rather than the amount of fat. We now know that a diet rich in monounsaturated fats such as the ones found in olive oil, nuts and seeds actually protects from many of these chronic diseases.

A recent Spanish study published in the scientific journal Diabetes Care showed that a Mediterranean style diet rich in olive oil reduces the risk of type II diabetes by almost 50 percent compared to a low fat diet. Type II diabetes is the most common and preventable form of diabetes.

The use of Mediterranean diet in the primary prevention of cardiovascular diseases.

The study included 418 participants who did not have diabetes. Each participant was randomly assigned to either a low fat diet, a Mediterranean diet with olive oil (up to 1 liter a week) or a Mediterranean diet with nuts (30 grams a day). After 4 years 17.9 percent of the individuals following the low fat diet developed diabetes, while only 10 percent of the participants following the Mediterranean with olive oil diet developed the disease.

When the two MedDiet groups (olive oil and nut groups) were pooled and compared with the low fat group, diabetes incidence was reduced by 52 percent. It is important to note that the reduction of diabetes risk was independent of changes in body weight or physical activity and that the Mediterranean diets that were followed were not calorie restricted.

Previous studies have shown that a Mediterranean style diet rich in olive oil may prevent the appearance of type II diabetes by improving blood sugar levels, insulin resistance and blood lipid levels.
