I first read about the health benefits of flavonol —the chocolate additive mentioned above — as an ingredient in beverages at Scientific Blogging. Diabetes.com reports on a chocolate bar with similar results. The folks at All Info About.com (???) helpfully warn us:

Of course, all research funded by companies with a commercial interest in the outcome has to be treated with caution but the scientists involved are well-respected so the outlook is hopeful. We shall await further, peer-reviewed research with interest.

Well, duh. Mars, Inc. is giddy, of course:

The findings have been met with enthusiasm by Mars. Chief scientific officer Harold Schmitz, PhD, said “the implications with regard to health and quality of life could be remarkable”. Paul Zimmet, MD, PhD, director of the International Diabetes Institute in Australia, was also upbeat about the potential. “While more research is needed, this study shows tremendous potential for future flavanol-based applications,” he said.
