In this study, the authors investigated the effect of regular consumption of two tropical food drinks, coconut (Cocos nucifera) water and mauby (Colubrina arborescens), on the control of hypertension. Twenty-eight hypertensive subjects were assigned to four equal groups and their systolic and diastolic blood pressures recorded for two weeks before and then for another two weeks while receiving one of four interventions. One group (the control) received bottled drinking water, the second group received coconut water, the third received mauby and the fourth group, a mixture of coconut water and mauby. Significant decreases in the mean systolic blood pressure were observed for 71%, 40% and 43% respectively of the groups receiving the coconut water, mauby and the mixture (p < or = 0.05). For these groups, the respective proportions showing significant decreases in the mean diastolic pressure were 29%, 40% and 57%. For the group receiving the mixture, the largest decreases in mean systolic and mean diastolic pressure were 24 mmHg and 15 mmHg respectively; these were approximately double the largest values seen with the single interventions.

Research Insights

  • Coconut Water→Reduced Blood Pressure

    For the group receiving the mixture, the largest decreases in mean systolic and mean diastolic pressure were 24 mmHg and 15 mmHg respectively; these were approximately double the largest values seen with the single interventions.

    Effect
    Beneficial
    Effect size
    Moderate
  • Coconut Water→Reduced Diastolic Blood Pressure

    For these groups, the respective proportions showing significant decreases in the mean diastolic pressure were 29% for the coconut water group.

    Effect
    Beneficial
    Effect size
    Small
  • Coconut Water→Reduced Systolic Blood Pressure

    Significant decreases in the mean systolic blood pressure were observed for 71% of the group receiving the coconut water (p ≤ 0.05).
