08 Sep 2017 --- Scientists have reported that a previously untested compound in coffee seems to improve cell function and insulin sensitivity in laboratory mice. The findings, which appear in a study in the American Chemical Society’s (ACS) Journal of Natural Products, could spur the development of new drugs to treat or even prevent Type 2 diabetes. In recent years, researchers have identified substances in coffee that could help to deal with the risk of developing Type 2 diabetes, a disease that nearly 30 million Americans suffer from. But few of these have been tested in animals.
