Coffee: Buzz Worthy for Health?

NYT just posted a piece coming this Sunday in its magazine, detailing the many newly-revealed or -confirmed ways drinking 2 to 4 cups of coffee a day aids your health, cuts some serious cancers and in general helps you live longer (studies show).   And: tests on mice, and now humans, suggest coffee may help stave off dementia.

In a 2012 study of humans, researchers from the University of South Florida and the University of Miami tested the blood levels of caffeine in older adults with mild cognitive impairment, or the first glimmer of serious forgetfulness, a common precursor of Alzheimer’s disease, and then re-evaluated them two to four years later. Participants with little or no caffeine circulating in their bloodstreams were far more likely to have progressed to full-blown Alzheimer’s than those whose blood indicated they’d had about three cups’ worth of caffeine.
