mediterranead diet

The first systematic review of related research confirms a positive impact on cognitive function, but an inconsistent effect on mild cognitive impairment

Over recent years many pieces of research have identified a link between adherence to a Mediterranean diet and a lower risk of age-related disease such as dementia.

Until now there has been no systematic review of such research, where a number of studies regarding a Mediterranean diet and cognitive function are reviewed for consistencies, common trends and inconsistencies.

A team of researchers from the University of Exeter Medical School, supported by the National Institute for Health Research Collaboration for Leadership in Applied Health Research and Care in the South West Peninsula (NIHR PenCLAHRC), has carried out the first such systematic review and their findings are published in Epidemiology.

The team analysed 12 eligible pieces of research, 11 observational studies and one randomised control trial.
