Impact of the Mediterranean Diet on Dementia Risk

Research indicates that adhering to a Mediterranean diet can lower the risk of developing dementia by approximately 23%, regardless of an individual's genetic predisposition. This conclusion stems from a population-based study involving over 60,000 participants from the UK Biobank. The study highlights a total of 882 dementia cases over nearly a decade, demonstrating the potential long-term brain health benefits associated with a diet rich in fruits, vegetables, whole grains, and healthy fats. These findings emphasize the importance of dietary choices in maintaining cognitive health as people age.

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.
