Mediterranean diet helps improve insulin sensitivity, glucose levels



The so-called "Mediterranean" diet, which is high in monounsaturated fats such as virgin olive oil, may help improve insulin sensitivity and decrease glucose levels in pre-diabetic patients, according to a study in the October 2007 issue of the Journal of the American College of Nutrition.

Researchers studied 11 people who were at risk of diabetes who had elevated blood glucose levels,

a body mass index of over 25, and other risk factors for diabetes. Participants followed one of three diets: a diet high in saturated fat, a diet rich in monounsaturated fat (MUFA), or a diet high in carbohydrates. Although none of the participants lost weight during the 28-day study, those who followed the MUFA diet had improved insulin sensitivity, lower glucose levels, and better cholesterol levels, especially if they ate a breakfast containing virgin olive oil.
