 After completing both acute 6 h postprandial study visits, subjects will roll over to the chronic phase of the study and receive a 2nd randomization sequence for consuming the active or the placebo beverage daily for 8 weeks. Before crossing over to the alternative treatment beverage for another 8 weeks, subjects will have a 4-week break wash out. Subjects will be counseled for a low polyphenolic diet throughout the study to consume the assigned beverage twice per day with lunch and evening meals except during 4-week washout.
