Mediterranean Diet, Retinopathy, Nephropathy, and Microvascular Diabetes Complications: A Post Hoc Analysis of a Randomized Trial
OBJECTIVE To date no clinical trials have evaluated the role of dietary patterns on the incidence of microvascular diabetes complications .  We hypothesized that a nutritional intervention based on the Mediterranean diet ( MedDiet ) would have greater protective effect on diabetic retinopathy and nephropathy than a low-fat control diet . RESEARCH DESIGN AND METHODS This was a post hoc analysis of a cohort of patients with type 2 diabetes participating in the PREvención con DIeta MEDiterránea ( PREDIMED ) study , a multicenter r and omized nutritional intervention trial conducted in a population at high cardiovascular risk . Individuals with type 2 diabetes who were free of microvascular complications at enrollment ( n = 3,614 , aged 55–80 years ) were r and omly assigned to one of three dietary interventions : MedDiet supplemented with extravirgin olive oil ( MedDiet+EVOO ) , MedDiet supplemented with mixed nuts ( MedDiet+Nuts ) , or a low-fat control diet . Two independent outcomes were considered : new onset of diabetic retinopathy and nephropathy . Hazard ratios ( HRs ) were calculated using multivariable-adjusted Cox regression . RESULTS During a median follow-up of 6.0 years , we identified 74 new cases of retinopathy and 168 of nephropathy . Compared with the control diet , multivariable-adjusted HRs for diabetic retinopathy were 0.56 ( 95 % CI 0.32–0.97 ) for the MedDiet+EVOO and 0.63 ( 0.35–1.11 ) for the MedDiet+Nuts . No between-group differences were found for nephropathy . When the yearly up date d information on adherence to the MedDiet was considered , the HR for retinopathy in the highest versus the lowest quintile was 0.34 ( 0.13–0.89 ; P = 0.001 for trend ) . No significant associations were found for nephropathy . CONCLUSIONS A MedDiet enriched with EVOO may protect against diabetic retinopathy but not diabetic nephropathy
The associations were largely consistent and significant among individuals from different socioeconomic background s and baseline characteristics .
