A Mediterranean diet can slash the risk of dementia by a quarter.
Eating a diet rich in fruit lowers the risk of dementia
New data suggests that eating a diet rich in fruits, vegetables and seafood may have a "protective effect" against dementia, irrespective of a person's genetic risk of developing the condition.
The promising early findings could pave the way for new preventive treatments if further research is able to validate the results.
Study co-author Dr. Janice Ranson, a senior research fellow at the University of Exeter, said: "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.
"The protective effect of this diet against dementia was evident regardless of a person's genetic risk, and so this is likely to be a beneficial lifestyle choice for people looking to make healthy dietary choices and reduce their risk of dementia."
