NEW EVIDENCE THAT DRINKING COFFEE MAY REDUCE THE RISK OF DIABETES
Scientists are
reporting new evidence that drinking coffee may help prevent diabetes and that
caffeine may be the ingredient largely responsible for this effect. Their
findings, among the first animal studies to demonstrate this apparent link,
appear in ACS' Journal of
Agricultural and Food Chemistry.

Horio and colleagues note that past studies have suggested that regular coffee
drinking may reduce the risk of type 2 diabetes. The disease affects millions
in the United States and is on the rise worldwide. However, little of that
evidence comes from studies on lab animals used to do research that cannot be
done in humans.
The scientists fed either water or coffee to a group of
laboratory mice commonly used to study diabetes. Coffee consumption prevented
the development of high-blood sugar and also improved insulin sensitivity in
the mice, thereby reducing the risk of diabetes. Coffee also caused a cascade
of other beneficial changes in the fatty liver and inflammatory adipocytokines
related to a reduced diabetes risk. Additional lab studies showed that caffeine
may be "one of the most effective anti-diabetic compounds in coffee,"
the scientists say.
