Outcomes
Primary Outcome Measures
Cognitive function
Change from baseline in cognitive test performance at 12 weeks
Secondary Outcome Measures
Cardiovascular risk factors
Fasting blood samples were collected at baseline and 12 weeks. Change from baseline in cardiovascular risk factors including blood lipid profiles, atherogenic risk ratios, blood glucose, hemoglobin A1c, insulin, and blood pressure at 12 weeks.
Oxidative stress markers
Fasting blood samples were collected at baseline and 12 weeks. Change from baseline in plasma 8-oxoguanine (ng/ml), plasma 8-hydroxy-2deoxy-guanosine (ng/mL), plasma hydroxynonenal (ng/ml), and plasma malondialdehyde (pmole/L) at 12 weeks.
Inflammatory markers
Fasting blood samples were collected at baseline and 12 weeks. Change from baseline in plasma tumor-necrosis factor-α (pg/mL) and plasma high-sensitivity C-reactive protein (ng/mL) at 12 weeks.

5. Study Description
Brief Summary
Tart cherries are a rich source of antioxidants. Studies have shown that tart cherries exert anti-oxidative and anti-inflammatory properties. The purpose of this study is to learn about the effects of drinking tart cherry juice on cardiovascular and cognitive health.
Detailed Description
Thirty-seven older adults were randomly assigned to drink 16 oz per day of either tart cherry juice or placebo drink for 12 weeks. Blood and urine samples were collected at baseline and 12 weeks to assess biomarkers. Physical activity and 3-day diet records were also collected throughout the study.
