Overseas health insurance customers might want to keep an eye on what they eat after it has been noted that the chances of developing dementia can be influenced by diet.
Alison Cranage, spokeswoman for Alzheimer's Research UK, said: "Some research has suggested that a diet low in fat, with lots of fruit and vegetables and including some oily fish can help lower our risk.
"A healthy diet together with regular exercise is the best way to help decrease our risk."
She added that people who already have dementia also need to watch what they eat.
Indeed, there is a risk that people with dementia can forget to eat and keep themselves well-hydrated.
Good health insurance could help to provide peace of mind that you will be well looked after should any problems arise with your mental health.
Research published recently in the journal Age and Ageing revealed that light-to-moderate alcohol consumption was shown to be inversely related to incident dementia among individuals aged 75 and above.
