Primary Outcome Measures:
  • Percent change of oxidant stress and lipid oxidation [ Time Frame: baseline, week 6, week 12 ]

Secondary Outcome Measures:
  • HbA1c [ Time Frame: baseline, week 6, week 12 ]
  • High Sensitivity C-reactive protein HsCRP [ Time Frame: baseline, week 6, week 12 ]

Enrollment: 26
Study Start Date: April 2008
Study Completion Date: November 2010
Primary Completion Date: April 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Pomegranate Juice Dietary Supplement: Pomegranate Juice
Group A drinks 8 oz. pomegranate juice/day for 12 weeks
Placebo Comparator: Placebo Juice (non-Pomegranate) Dietary Supplement: Placebo Juice
Group B drinks 8 oz. placebo juice/day for 12 weeks

Detailed Description:
This research study will evaluate how pomegranate juice (or a placebo juice) affects the body. Participants will be asked to drink 8 oz. of juice daily for 12 weeks. Biomarkers, which are indicators of health, will be measured throughout the study. They are present in blood and urine. The placebo is a juice that is not made from pomegranates, but resembles pomegranate juice in color and taste. Eating pomegranates has been shown to have a positive impact on certain biomarkers. Recent studies have shown that biomarkers can be indicators of general health. The investigators want to know if drinking pomegranate juice daily for 12 weeks is effective at improving a variety of biomarkers in diabetic adults.
