Expatriate health insurance customers might be interested to learn that getting the right nutrients is "vital for brain function".
According to Nancy Morse, senior scientific officer at Efamol, fish oil components such as docasahexaenoic acid (DHA) are especially important in limiting issues like memory loss in older people.
However, she suggested that people are not getting enough of DHA at the moment, despite the fact that research has shown "people with lower than normal levels of DHA, have a greater tendency to experience memory problems as they age".
Earlier this year, surveys conducted by Efalex revealed that 51 per cent of people aged 50 and above admit to worrying about their health more than they do any other single issue.
A further 71.3 per cent admitted to experiencing short-term memory problems, with more than half noting that they had avoid addressing people close to them by their name because they had forgotten it.
