Mediterranean Diet with EVOO reduces by 44% the risk of Diabetic Retinopathy

2015/29/09 - After six years of studying a large population of diabetics, researchers of the Predimed trial (Prevention with Mediterranean Diet) have shown that a Mediterranean Diet supplemented with extra virgin olive oil can reduce up to 44% the risk of diabetic retinopathy, the leading cause of blindness in these patients.

This study involved 3,614 men and women between 55 and 80 years, with an average of 67 years with type 2 diabetes who were part of the Predimed trial, a multicenter randomized nutrition intervention study conducted in a population at high cardiovascular risk in order to evaluate the importance of the Mediterranean Diet on cardiovascular prevention, as recorded by the CIBERobn Carlos III Institute of Health in its website.

Participants were divided into three groups and were assigned randomly to one of three dietary interventions: tips to follow a Mediterranean Diet supplemented with extra virgin olive oil; advice to follow a Mediterranean Diet supplemented with nuts; and finally tips to follow a low-fat Diet both animal and vegetable origin (control group).

During six years of follow-up 74 new cases of diabetic retinopathy and 168 cases of nephropathy were identified. As for diabetic retinopathy, significant differences between those who followed the Mediterranean Diet and those who didn't were found. Those who supplemented with nuts had a nonsignificant risk reduction of 37% compared to the control group.

The main objective of the intervention in the Predimed trial was to change the overall dietary pattern instead of focusing on changes in macro and micronutrients. It was found that participants who made a careful monitoring of the Mediterranean Diet during follow-up showed larger reductions in the incidence of retinopathy.

As recorded CIBERobn, the mechanisms through which the Mediterranean Diet may protect diabetic retinopathy need to continue investigations. A diet rich in vegetables, fruits, nuts, whole grains, beans and extra virgin olive oil provide certain minerals, antioxidants and other phytochemicals that improve oxidative stress, inflammatory processes and insulin resistance that would prevent progression in this complication of diabetes. In fact, other observational studies have found that diabetics who take lots of vegetables and fruits have a lower risk of developing diabetic retinopathy.

This work was published last September 14th in the Diabetes Care journal and has been carried out by scientists (Andrés Díaz-López, Nancy Babio and Josep Basora) of Predimed project led by Professor Jordi Salas-Salvadó, Chief of Human Nutrition Unit at the University Rovira i Virgili, and members of the University Hospital Sant Joan de Reus, the Health Research Institute Pere Virgili and the Institut Català de la Salut.
