The author of the study, Dr. Albert Ascherio, spoke to The New York Times and admitted that more research is needed: "We know that caffeine enters the brain and activates the release of different neurotransmitters that are related to mood, like dopamine and serotonin . . . That may explain the short-term effects on mood. But the long-term mechanisms of caffeine intake on mood we don't really know." While the researchers aren't quite ready to recommend that women drink more coffee, Dr. Ascherio says personal responsibility is key: "We self-medicate ourselves with caffeine, and each person usually knows their optimal level."
Are you convinced? Do you think drinking coffee can lower the risk of depression?
