Coffee has Benefits Beyond Morning Boost!

CoffeeCaffeine Linked to Lower Depression Risk….

A recent arm of the Nurses Health Study tracking 51,000 women average age of 63, found a lower incidence of depression in those that consumed four or more cups of coffee a day. 

Women consuming 4 or more cups a day, a habit many in the work world have, have a 20% decreased risk of being depressed or developing clinical depression.   Those that drink 2 or more cups had a 15% reduction.   All were compared to those drinking only one cup per day.    Decaf varieties have no documented benefit in preventing depression.

The study was published in the September 26, 2011 issue of Archives of Internal Medicine.  Dr. Alberto Ascherio, professor of epidemiology and nutrition at Harvard School of Public Health and professor of medicine at Harvard Medical School was the lead author of the study and he states, “Caffeine has short-term positive effects on mood, subjective feelings of having more energy and being more awake in the short term.” 

“Caffeine is known to affect the release of several neurotransmitters, including dopamine and serotonin, that had been implicated in regulating mood and depression,” Dr. Ascherio said. 

The caveat here is first discovering that caffeine has antidepressant benefits and secondly that this study could lead to further research on stronger compounds that curb depression.
