Primary Outcome Measures

Name	Time	Method
Change from Baseline and Placebo in Uric Acid Level in Patients Randomized to Treatment Group	Baseline, ~30 days later	Percent change in uric acid level from baseline after 30 days of treatment with blueberry powder. Since this is designed as a crossover trial, baseline could represent uric acid level at the beginning of the study or after at least a 2-week washout period following placebo administration.

Secondary Outcome Measures

Name	Time	Method
Body Weight	Baseline, ~30 days, ~45 days, ~75 days	Percent change and absolute change of body weight from baseline and placebo
Blood Pressure	Baseline, ~30 days, ~45 days, ~75 days	Percent change and absolute change of blood pressure from baseline and placebo
Quality of Life	Baseline, ~30 days, ~45 days, ~75 days	Quality of life will be assessed using the Health Assessment Questionnaire-Disability Index (HAQ-DI)
