A recent study has linked high-protein diets to a smaller brain size, raising concerns that such a diet could lead to a higher risk of dementia in later life.
Dr Susanne Sorensen, the head of research at the Alzheimer's Society, explained that while the research is very interesting, it is hard to tell whether or not people would have had the same outcome without the tests.
She maintained, however, that further research is needed into this phenomenon, as there could certainly be a way to reduce vulnerability to dementia and Alzheimer's disease through diet alone.
Until then, Dr Sorensen recommended: "It is important to eat a diet rich in fruit, vegetables and fish. People who want to reduce their risk of dementia should also take regular exercise, refrain from smoking and get their blood pressure and cholesterol checked."
Dementia is caused by the build-up of protein plaques on the brain formed by a compound known as amyloid beta, causing the brain to shrink in size.
