Brief summary

This study was a randomized, placebo-controlled, crossover, pilot dietary intervention. Ocean Spray Cranberries, Inc provided the experimental and placebo beverages, which have been validated and used in previous studies \[26-29\]. Both beverages were similar in appearance, taste, and aroma and assigned to volunteers according to computer-generated random orders. Both investigators and participants were blind to the assignment and products are identified by a random 3-digit code pre-printed on the cap. The participants consumed either cranberry juice or placebo beverage daily (8 fl oz per day) for 15 days
