Following a Mediterranean diet was found to reduce the risk of diaÂbetes by about 30 perÂcent comÂpared to a low fat diet in a trial involvÂing over 3,500 high-risk parÂticÂiÂpants in Spain. The study, pubÂlished in the Annals of Internal Medicine, showed that adherÂence to the Mediterranean diet, parÂticÂuÂlarly with extra virÂgin olive oil, may help preÂvent diaÂbetes in indiÂvidÂuÂals at high risk for heart disÂease.

In the latÂest trial of the ongoÂing interÂvenÂtion study PREDIMED, Spanish researchers found that folÂlowÂing a Mediterranean diet may cut the risk of diaÂbetes by about 30 perÂcnt comÂpared to the conÂtrol diet, which was charÂacÂterÂized as a low fat diet.
The study pubÂlished in the Annals of Internal Medicine, involved 3,541 men and women who were a subÂgroup of the larger PREDIMED study that enrolled over 7,000 parÂticÂiÂpants from seven comÂmuÂniÂties in Spain since 2003. The men and women for this parÂticÂuÂlar trial were between 55 and 80 years of age and at high risk for heart disÂease, but withÂout diaÂbetes.
As is stanÂdard with the PREDIMED study, the parÂticÂiÂpants were assigned to one of three diets: Mediterranean diet supÂpleÂmented with extra-virÂgin olive oil, Mediterranean diet supÂpleÂmented with nuts, or a conÂtrol diet (parÂticÂiÂpants were advised to folÂlow a low fat diet). The parÂticÂiÂpants were not asked to exerÂcise or lose weight.
At folÂlow up which was on averÂage 4.1 years, 101 indiÂvidÂuÂals from the conÂtrol group develÂoped diaÂbetes, while only 80 indiÂvidÂuÂals from the olive oil Mediterranean diet group develÂoped the disÂease. The researchers noted that adherÂence was much higher in the Mediterranean diet groups and conÂcluded that a Mediterranean diet enriched with extra virÂgin olive oil withÂout caloric limÂiÂtaÂtions may reduce diaÂbetes risk in indiÂvidÂuÂals with a high heart disÂease risk.
This is not the first time that the Mediterranean diet has been found to have a preÂvenÂtaÂtive effect against diaÂbetes. In 2011 a smaller trial (418 parÂticÂiÂpants) of the PREDIMED study showed that a Mediterranean diet reduced the risk of type II diaÂbetes by almost 50 perÂcent comÂpared to a low fat diet.
