http://news.bbc.co.uk/2/hi/health/8615456.stmThe foods we choose to eat may determine our risk of dementia, mounting evidence suggests.Latest work in Archives of Neurology shows sticking to a diet rich in nuts, fish and vegetables significantly cuts the chance of developing Alzheimer's.
A "Mediterranean diet" containing plenty of fresh produce and less high-fat dairy and red meat has long been thought to improve general health.
