Having three cups of coffee a day can significantly reduce the chance of developing Alzheimer's disease, say researchers.
A ten-year study of 600 elderly men found those getting a regular caffeine fix experienced a much smaller decline in their mental abilities than non coffee-drinkers.
The results support earlier studies that show coffee has a protective effect on the brain.
Researchers believe caffeine may trigger a chain reaction in the brain that prevents the damage of Alzheimer's.
In a report on their findings, published in the European Journal of Clinical Nutrition, they raised the possibility that doctors may one day recommend coffee to the elderly.
"Drinking three cups a day was associated with the smallest cognitive decline," they said."
