BEIJING, Sept. 27 (Xinhuanet) -- Scientists have been making great efforts to show how harmful coffee is to us, though no evidence yet. A latest study may be reassuring1 for coffee-lovers.
Women who drink caffeinated coffee are less likely to be
depressed2 than those don't. And the more they drink, the lower risk of developing depression, according to a study published Monday in the Archives of Internal Medicine.
Researchers of the study tracked the health of over 50,000 women
aged3 between 30 and 55 in 1996 for a decade and recorded their mental health and coffee
intake4 periodically.
They find that women who drank two or three cups of coffee per day were 15 percent less likely than those who drank little or decaffeinated coffee to be depressed.
And for those who drank four or more cups, the risk of developing depression reduced by 20 percent.
The reason why coffee could protect depression is not clear. But the scientists from the Harvard University speculated that caffeine was the key player. More research is needed to show whether caffeine can
ward5 off depression.
It might be that not-depressed people tended to be more
activated6 and the habit of coffee drinking just fit in their lifestyle.
However, the depressed ones, who might suffer from
sleeplessness7, chose not to drink coffee because the caffeine might
exacerbate8 it.
"There's no need to start drinking coffee," said Dr. Alberto Ascherio, the senior author of the study, "The message is that coffee is safe to drink, with no
adverse9 effects. That's really all that can be said."
