Olive Oil Diet Reduces Risk of Type 2 Diabetes
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.
Individuals who are obese or overweight and have metabolic syndrome are at highest risk for developing this form of diabetes. The study is part of PREDIMED, a long-term nutritional intervention study aimed to assess the efficacy of the Mediterranean diet in the primary prevention of cardiovascular diseases, and is composed of a multidisciplinary team of 16 groups distributed in 7 autonomous communities in Spain.
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.
