International health insurance customers might want to discuss healthy eating and exercise solutions with their doctor.
According to recent comments from one doctor, maintaining a healthy lifestyle could lower the risk of developing dementia.
Dr Simon Ridley, head of research at Alzheimer's Research UK, said that there is nothing to confirm that a particular food affects the chance of developing the disease but following a healthy, balanced diet could be beneficial.
Dr Ridley added: "We don't yet fully understand what causes dementia, but it's likely to be a complex mix of genetics and environmental factors, such as diet, lifestyle and exercise.
"Scientists are making real progress in this area, and if we can unravel the causes of dementia, we stand a much better chance of developing treatments."
The comments follow studies from the Karolinkska Institutet, which found that being overweight or obese during middle age can increase the likelihood of developing dementia later in life.
