The Sydney Morning Herald reported that:
Coffee drinkers have a substantially lower risk of developing type 2 diabetes than people who abstain from the beverage, a new study shows.
This ‘striking’ protective effect was seen in former coffee drinkers as well, Besa Smith and co-investigators at the University of California San Diego in La Jolla report.
"The growing body of literature definitely suggests strongly ... that there is something there," she told Reuters Health in an interview. Just what that something is isn't clear, but it's probably not caffeine, she said, because the effect has also been observed with decaffeinated coffee.
The researchers were unable to determine how much coffee people needed to drink to produce the protective effect. But study participants were generally not heavy coffee drinkers, Smith said.
"Given the increasing prevalence of obesity, impaired glucose tolerance, and diabetes, and the fact that the majority of adults in most of the Westernised world drink coffee daily, a coffee benefit could have widespread impact," she and her colleagues conclude. "Further investigation is warranted."
Indeed, though ;-) blokes like KTemoc don't need such medical research to tell us we have been doing the 'right thing' all along. Hmmm, I better continue supporting her investigation with more ‘personal’ data.
