Drinking coffee may do more than just keep you awake. A new study suggests an intriguing potential link to mental health later in life.
A team of Scandinavian researchers tracked coffee consumption in 1500 middle-aged men and women for an average of 21 years. About a hundred of them developed Alzheimer’s Disease and dementia.
The scientists found that the subjects who drank three to five cups of coffee daily were 65 percent less likely to have developed dementia, compared with those who drank two cups or less. People who drank more than five cups a day also were at reduced risk . It may be because the coffee has an antioxidant effect or because it lowers the risk of type 2 diabetes which in turn raises the risk of dementia.
The researchers aren’t suggesting you should taking up a java habit as a preventive health measure. But if you already enjoy a jolt of caffeine, keep drinking.
