Your morning "cup of Joe" may do more than deliver the jolt you need to get going -- it may also help you stave off type 2 diabetes, a new study suggests.

But, before you pour yourself a second cup know this: The study authors said their research was done with cell cultures and there's no proof yet that coffee has any ability to keep type 2 diabetes at bay.

Past research has suggested a link between coffee and a reduced risk of type 2 diabetes, and now Chinese researchers behind the new study think they may know why that may be so. They found three major compounds in coffee that may provide potentially beneficial effects: caffeic acid, chlorogenic acid and caffeine.

"These findings suggest that the beneficial effects of coffee consumption on type 2 diabetes mellitus may be partly due to the ability of the major coffee components and metabolites to inhibit the toxic aggregation of hIAPP [human islet amyloid polypeptide]," Ling Zheng, professor of cellular biology at Wuhan University in China, and colleagues wrote.
