Natural compounds in cocoa tied to blood flow improvements for adults with type 2 diabetes
Date:5/26/2008

h type 2 diabetes a population known to have impaired blood vessel function, putting them at higher risk for cardiovascular disease drank a well-characterized and standardized cocoa beverage made using the Mars Cocoapro process that contained different flavanol levels, ranging from 75 to 963 milligrams, and had their blood vessel function measured for several hours following consumption. The researchers found a positive correlation between the flavanol dose consumed and immediate improvements in FMD (flow mediated dilation, a measure of vessel health, i.e. the ability of a vessel to relax).

In a subsequent controlled 30-day, double-masked clinical trial, adults with established diabetes who were medically controlled, drank either a flavanol-containing cocoa beverage or a low-flavanol control three times a day. The cocoa beverages contained either 25 milligrams of cocoa flavanols (control) or 321 milligrams of cocoa flavanols (treatment) and were matched for calories, nutrients and other cocoa compounds such as theobromine and caffeine.

Beyond the immediate improvements in FMD following flavanol consumption, participants experienced sustained improvements in blood vessel function upon consuming the flavanol-containing cocoa over a period of 30 days (30 percent increase in FMD between day one and 30).

We were pleasantly surprised by the magnitude of impact of cocoa flavanols on vascular function in these diabetic adults, said Mars, Incorporated Chief Science Officer Harold Schmitz, PhD. If a dietary intervention with cocoa flavanols can produce such profound, sustained improvements in vascular function on-top of standard medication in a population with increased risk for cardiovascular diseases, the implications with regard to health and quality of life could be remarkable.

While this study is very promising, the researchers indicate that larger trials are necessary to fully demonstrate the clinical relevance of flavanol-rich foods
