Good Diet Equals Health

By Dr. Lorna Mistranski

Research has shown that a traditional Mediterranean diet provides assistance in protecting the body from type 2 diabetes.

The composites of what make the Mediterranean diet so perfect against type 2 is it is robust in olive oil, grains, nuts vegetables, and fish yet it is low in meat, alcohol, and dairy products.

Current evidence suggests that such a diet has a protective role in cardiovascular disease, but little is known about how this diet effects those with type 2 diabetes.

The study involved over 13,000 graduates from the University of Navarra in Spain with no history of diabetes, and were recruited between December 1999 and November 2007;each participant had their dietary habits and health were tracked.

To start the study off, the graduates all completed a questionnaire designed by the developers of the project. The questions were summarized at 136 and asked the participants specific questions that related to how they cooked, what types of oils they used, and their dietary supplements.

The participants were then notified every two years by a questionnaire that asked each about their diet, lifestyle, and other medical conditions. From this information, researchers were able to pick up new cases of diabetes

During the follow-up period (median 4.4 years) the researchers from the University of Navarra found that participants who stuck closely to the diet had a lower risk of diabetes. A high adherence to the diet was associated with an 83% relative reduction in the risk of developing diabetes.

Interestingly, those participants who stuck strictly to the diet were expected to have the highest prevalence of risk factors for diabetes such as they got older with age, a family history of diabetes, and a higher proportion of ex-smokers.

This assumption proved to be false; If fact, say the authors, they had a lower risk of diabetes, suggesting that the diet might provide substantial protection.

The characteristics of the diet include a high intake of fiber and vegetable fat, a low intake of trans fatty acids, and a moderate intake of alcohol.

A key element of the diet is the abundant use of virgin oil for cooking, frying, spreading on bread, and dressing salads.

The scientist finished by calling for larger cohorts and trials to confirm their findings. - 17273
