Can your daily cup o' joe actually help lower your depression risk? Research suggests that this may be true, at least for older women. An article in the Archives of Internal Medicine reports that the more coffee the women studied consumed, the lower their risk of depression was.
However, it appeared that it was actually the caffeine in the coffee, rather than the coffee itself, that had the protective effect. Women who drank caffeinated coffee had a gradually decreasing level of risk, depending how many cups of caffeinated coffee that they drank, while women who drank decaffeinated coffee experienced no change in their level of depression risk.
The authors noted, however, that the type of study that they conducted was not able to prove that caffeine can protect you from depression. Further research will be necessary to prove this. It does suggest, however, that it could help.
Caffeine is commonly found in coffee, tea, sodas and chocolate.
The study appears in the September 2011 issue of the journal.
