Brief Summary

This study aims to provide evidence as to whether consumption of tart cherry juice can reduce the risk of gout and cardiovascular disease (CVD) in an acute context. The proposed study is a 2-way cross-over, randomised, placebo-controlled trial and aims to answer the following research questions:

  1. 1.What effect does a single 30mL serving of tart cherry concentrate have on serum uric acid and urinary excretion of uric acid in healthy individuals, when compared with water?
  2. 2.What effect does a single 30mL serving of tart cherry concentrate have on markers of cardiovascular disease risk and oxidative stress in healthy individuals, when compared with water?

Outcome Measures

Primary Outcomes (1)

  • Change in serum urate (in millimoles per litre (mmol/l)

    Difference in serum urate in tart cherry juice arm versus water arm from baseline to 24 hours post-consumption of drink. Measured using a commercial fluorometric/colorimetric urate assay kit.

    Measured at baseline, 1, 2, 3, 5 and 24 hours post-consumption of test drink

Secondary Outcomes (7)

  • Change in urinary urate (mmol/l)

    Measured from samples collected at baseline and between 0-2 hours, 2-4 hours, 4-5 hours, 5-8 hours, 8-11 hours and 11-24 hours

  • Change in urinary creatinine (mmol/l)

    Measured from samples collected at baseline and between 0-2 hours, 2-4 hours, 4-5 hours, 5-8 hours, 8-11 hours and 11-24 hours

  • Change in serum creatinine (mmol/l)

    Measured at baseline, 1, 2, 3, 5 and 24 hours post-consumption of test drink

  • Change in c reactive protein (in milligrams per litre (mg/l)

    Measured at baseline, 2 and 5 hours post-consumption of test drink

  • Change in blood pressure (in millimetres of mercury (mmHg))

    Measured at baseline, 1, 2, 3, 5, and 24-hours post-consumption of test drink

  • +2 more secondary outcomes

Other Outcomes (2)

  • Avoidance of strenuous physical activity

    Measured from 72-hours prior to the study until 24-hours post-consumption of test drink

  • Adherence to a low-polyphenolic diet

    Measured from 48-hours prior to the study until 24-hours post-consumption of test drink

Study Arms (2)

Tart cherry juice

EXPERIMENTAL

30 mL tart cherry concentrate (CherryActive, UK, 100% Montmorency) diluted with 220 mL water (totalling 250 mL). According to available manufacturers data, this is equivalent to consuming 90-100 fresh cherries.

Dietary Supplement: Tart cherry juice

Water

OTHER

250 mL water (neutral control)

Other: Water

Interventions

Tart cherry juiceDIETARY_SUPPLEMENT

250 mL tart cherry juice (30 mL tart cherry concentrate \[CherryActive, UK\] diluted with 220 mL water) is consumed on a single occasion by each participant. This will be consumed immediately following the baseline measurements one laboratory visit.
