Drink On...

...coffee that is!!

Drinking coffee may do more than just keep you awake. A new study suggests an intriguing potential link to mental health later in life, as well.

A team of Swedish and Danish researchers tracked coffee consumption in a group of 1,409 middle-age men and women for an average of 21 years. During that time, 61 participants developed dementia, 48 with Alzheimer’s disease.

After controlling for numerous socioeconomic and health factors, including high cholesterol and high blood pressure, the scientists found that the subjects who had reported drinking 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 of dementia, the researchers said, but there were not enough people in this group to draw statistically significant conclusions.

Dr. Miia Kivipelto, an associate professor of neurology at the Karolinska Institute in Stockholm and lead author of the study, does not as yet advocate drinking coffee as a preventive health measure. “This is an observational study,” she said. “We have no evidence that for people who are not drinking coffee, taking up drinking will have a protective effect.”(note to self- glad I am already drinking coffee!)

Dr. Kivipelto and her colleagues suggest several possibilities for why coffee might reduce the risk of dementia later in life. First, earlier studies have linked coffee consumption with a decreased risk of type 2 diabetes, which in turn has been associated with a greater risk of dementia. In animal studies, caffeine has been shown to reduce the formation of amyloid plaques in the brain, one of the hallmarks of Alzheimer’s disease. Finally, coffee may have an antioxidant effect in the bloodstream, reducing vascular risk factors for dementia.

Dr. Kivipelto noted that previous studies have shown that coffee drinking may also be linked to a reduced risk of Parkinson’s disease.

Glad there are many studies showing the great effects of coffee- not that it matters, I would still drink it! lol

So here's what I figure. If smoking kills and second hand smoke can supposedly have similar effects on people (some say stronger effects?), I figure I should be one of the mentally healthiest people around with all the second hand coffee I absorb from the many coffee drinkers in my life!
