Does the Mediterranean Diet Lower the Risk of Dementia?
Thanks for asking. 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.
So joint lead author of the study, Dr.
Janice Ranson, a senior research fellow at the University of Exeter for the Guardian newspaper.
What did the researchers find?
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.
Their findings, which were published in the journal BMC Medicine, are based on data from more than 60,000 individuals from the UK Biobank, an online database of medical and lifestyle records for more than half a million Britons.
The dementia impacts the lives of millions of individuals throughout the world, and there are currently limited options for treating this condition.

What foods are included?
The Mediterranean diet prioritises plant-based cooking.
Fruit and vegetables should make up the majority of each meal, as well as whole grains, beans, seeds and nuts.
Extra virgin olive oil should be used rather than butter and other fats are rarely consumed.
Refined sugar or flour are also avoided as much as possible.
Likewise, meat is seldom on the menu, rather fish is favoured.
Meals may include eggs, dairy and poultry, but in smaller portions.
Is diet the only factor?
Professor David Curtis from UCL's Genetic Institute said the study did not take into account that people who follow this type of diet may have a healthier lifestyle overall, saying, It's not clear that such a diet itself reduces dementia risk, although it's plausible that it might do so.
Dr. Duan Mella, a dietitian and lecturer at Aston University, who was not part of the study, said, The Mediterranean way of eating is not just about food on plates.
It's about the social interactions linked to food and people who socialise more have lower risks of dementia and other conditions.
