Three coffees a day keeps dementia at bay
By Rachel Ellis


DRINKING at least three cups of coffee a day can reduce the risk of
developing alzheimers disease by as much as 60 per cent.


New research shows that healthy elderly people, with no signs of the brain
disease, had consumed an average of three to four cups a day since the age of
25. However, those with the debilitating illness drank, on average, just one

protects against alzheimers, an incurable disorder that causes disorientation
and memory loss
