Mounting evidence suggests the foods we choose to eat may determine our risk of dementia. 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. Dr Yian Gu and colleagues at Columbia University Medical Centre in the US studied the diets of 2,148 retirement-age adults living in New York. Over the four years of the study, 253 of these older adults developed Alzheimer's disease. When the researchers scrutinised the diets of all of the individuals in the study, a pattern emerged. Adults whose diets included more salad dressing, nuts, fish, poultry, fruits and green leafy vegetables, and less high-fat dairy, red meat and butter, were far less likely to develop dementia. Rebecca Wood, chief executive of the Alzheimer's Research Trust, said understanding the connection between diet and dementia risk may help prevent the development of diseases like Alzheimer's for some people.<br/>
