According to the Archives of Neurology, those who adhered most to diets rich in dark, leafy vegetables, poultry, fish and nuts and low in red meat, butter and fatty dairy products had a 38 per cent lower risk of getting Alzheimer's disease than those who followed that plan the least.

These foods may protect blood vessels in the brain, preventing tiny strokes that contribute to Alzheimer's, said Nikolaos Scarmeas, author of this study. There's no cure for Alzheimer's, which causes memory loss that can devolve into cognitive decline. About 30 million people worldwide have the disease.

Researchers tracked subjects for four years, checking in every 1.5 years to document dietary patterns and neurological status. No participant had dementia when the study began, and 253 developed Alzheimer's disease throughout the four years.

The dietary pattern that was linked most to a lowered risk also consisted of oil-and-vinegar salad dressing, tomatoes, broccoli, cauliflower and fruit, the researchers said.
