Brief Summary

Aronia berries are a native North American berry with high naturally occurring anthocyanins among other polyphenols. Based on their polyphenol composition, there is growing interest in the potential for Aronia berries to elicit health promoting cardio-metabolic effects. Specifically, Aronia berry extracts, which provide a concentrated source of polyphenols, may improve blood vessel function. Thus, the primary focus of this project is to evaluate the effects of Aronia berry polyphenols on blood pressure and other biomarkers of cardiovascular disease risk such as endothelial function, arterial stiffness and blood lipids.
