Brief Summary

In this study, the investigators recruited at-risk individuals (n=26) who were overweight (25.0-29.9 kg/m2) and obese (\> 30.0 kg/m2) and likely to exhibit one or more conditions associated with Metabolic Syndrome (MetS). In this 12-week placebo-controlled 2 x 2 crossover dietary intervention, the investigators randomized participants to consume 240 mL (8 ounces) daily of either placebo (artificial cherry-flavored, anthocyanin-free beverage) or TCJ for 4 weeks, followed by a 4-week washout period, then consumption of the alternate beverage for 4 weeks. Subsequently, the investigators determined the effect of TCJ in at-risk participants on markers of uricemia, lipidemia, glycemia, and inflammation.

Outcome Measures

Primary Outcomes (1)

  • serum uric acid

    Hyperuricemia contributes to gout, a frequently occurring, complex rheumatologic form of inflammatory arthritis. The primary outcome measure of this study was serum uric acid and its reduction by TCJ consumption.

    4 weeks

Secondary Outcomes (2)

  • High sensitivity C-reactive protein (hsCRP)

    4 weeks

  • Serum triglycerides

    4 weeks

Study Arms (2)

Tart cherry juice (TCJ)

ACTIVE COMPARATOR

Participants randomized to consume either placebo beverage or tart cherry juice at beginning of the study followed by a 4 week washout then switch over to the alternate beverage to account for timing and order effects.

Dietary Supplement: Tart cherry juice

Placebo

PLACEBO COMPARATOR

Participants randomized to consume either placebo beverage or tart cherry juice at beginning of the study followed by a 4 week washout then switch over to the alternate beverage to account for timing and order effects.

Other: Placebo

Interventions

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • This study was a 12-week 2 x 2 crossover, randomized, placebo-controlled dietary intervention in overweight and obese participants (BMI\>25.0 kg/m2) who are more likely to exhibit \>1 of the 5 risk conditions associated with metabolic syndrome (MetS). BMI was the minimal criterion for recruitment.

You may not qualify if:

  • Participants were \>18 years of age, not pregnant, not diabetic, with no unresolved infections or diseases (diabetes, CVD, IBD, cancer and liver disease), and nonsmokers. Histories of medication and dietary supplement use were collected and those taking anti-inflammatory or lipid-lowering medications were excluded.
