NCT02764203

Brief Summary

The COCOA-BP Trial is designed to assess the impact of 50g daily dark chocolate intake on blood pressure and compare outcome data derived from wearable/digital health devices to data derived from standard methods. Additionally, the usability of the wearable technology will be evaluated.

Outcome Measures

Primary Outcomes (1)

  • Change in resting systolic blood pressure after daily dark chocolate

    14 days after daily consumption of dark chocolate

Secondary Outcomes (3)

  • Correlation of physical activity (steps) to resting blood pressure and heart rate

    daily, for four weeks

  • Comparison of blood pressure derived from wearable digital health devices to data derived from standard methods

    End of week two and end of week four

  • Comparison of heart rate derived from wearable digital health devices to data derived from standard methods

    End of week two and end of week four

Study Arms (1)

Chocolate consumption

EXPERIMENTAL

Subjects will consume 50g of dark chocolate for 2 weeks and have their blood pressure compared before chocolate and after chocolate

Other: Dark ChocolateDevice: Wearable devices

Interventions

50g dark chocolate consumed for a period of 2 weeks

Chocolate consumption

Up to three wearable devices will be worn by the subject to measure parameters such as heart rate, blood pressure and number of steps

Chocolate consumption
