Coffee drinking may cut dementia risk

Coffee lovers drink up. A study in the Journal of Alzheimer's Disease found those who drank three to five cups of coffee a day in middle age were two-thirds less likely than non-drinkers to develop dementia.

No one is recommending that people start drinking coffee to ward off any disease though.

Scientists don't know if it's components of coffee itself, such as the caffeine or certain antioxidants, or something else about coffee drinkers that explains the observations.

Whether coffee itself deserves the credit is still not clear, but researchers say the findings at least suggest that coffee drinkers can enjoy that morning cup in good conscience.
