Drinking coffee, a lots of it, may help prevent type 2 diabetes, a disease affecting millions and on the rise across the globe, according to a new study published in the American Chemical Society's Journal of Agricultural and Food Chemistry.
It's the caffeine, say scientists from Nagoya University in Japan.
The scientists fed either water or coffee to a group of lab mice, a common stand-in for people in such studies. The coffee consumption prevented development of high-blood sugar and improved insulin sensitivity in the mice. That means lower risk of diabetes.
