Researchers from Greece, the Czech Republic, and the United States collaborated to follow more than 17,000 individuals for approximately 4 years to evaluate the effects of the Mediterranean Diet on cognitive status. Using Food Frequency Questionnaires, they determined that higher adherence to the Mediterranean Diet was associated with lower likelihood of incident cognitive impairment, even after adjusting for demographic characteristics, environmental factors, vascular risk factors, depressive symptoms, and self-reported health status. Although higher adherence to the Mediterranean Diet reduced risk of incident cognitive impairment in nondiabetic individuals, it did not yield the same results in patients with diabetes.
