Fish in diet prevents dementia

Recent research in Finland indicates that eating a diet rich in tuna and other fish could help lower risks of suffering a stroke and developing cognitive decline . Researchers at the University of Kuopio studied 3,660 people aged 65 or older.
Those that ate fish high in omega-3 fatty acids three times or more per week were found to have a 26 per cent lower risk of having silent brain lesions – which can cause stroke and dementia .
Fish, including tuna and salmon, could protect against memory loss . However, to be effective as part of a healthy diet, fish had to be grilled or baked, rather than fried. The study was published in the most recent issue of Neurology .
