Effect of Long Term Cocoa Flavanol Intake on Blood Pressure and Platelet Function in Healthy Adults, Part 2

Not Applicable

Completed

• Conditions: Healthy

• Registration Number: NCT02447783
• Lead Sponsor: University of California, Davis

Brief Summary

Flavanols are plant-derived compounds commonly present in the human diet. Examples of flavanol-containing foods and beverages are apples, chocolate, tea, wine, berries, pomegranate and nuts. The consumption of flavanol-containing foods and beverages has been associated with improvements in cardiovascular health. In this study, the investigators hope to learn more about the effects of long term consumptions of cocoa flavanols on blood pressure, platelet function and other metabolic parameters in healthy humans. This study is a continuation of a previous study investigating the consumptions of increasing amounts of cocoa flavanols on blood pressure, platelet function and other metabolic parameters in healthy humans
