The purpose of this study is to investigate how well the phytochemicals present in a cranberry beverage are absorbed into your body, and whether they can lower certain risk factors for heart disease and type 2 diabetes. Participants will be asked to consume one 15.2 ounce bottle of a beverage (cranberry beverage or placebo beverage with no cranberry) daily for 8 weeks, and have blood and urine samples collected.
