Does the Mediterranean diet lower risks of dementia?

According to new research a mediterranean diet could lower the risk of dementia by a quarter regardless of a person's genetic risk. “The findings from this large population-based study underscore the long-term brain health benefits of consuming a Mediterranean diet, which is rich in fruits, vegetables, whole grains, and healthy fats," said Joint lead author of the study, Dr Janice Ranson, a senior research fellow at the University of Exeter, for the Guardian newspaper. 
The researchers measured people, who did and did not follow a Mediterranean diet, and took into account each individual’s genetic risk for dementia. Over nearly a decade, there were 882 cases of dementia, but those who followed a strict Mediterranean diet had a 23% lower risk of developing the condition.
