Effects of pomegranate juice on blood pressure in hypertensive individuals

Pomegranate juice is rich in bioactive phytochemicals with antioxidant, and anti-inflammatory and cardioprotective functions. The present trial investigated the acute effects of Pomegranate juice consumption on blood pressure and markers of endothelial function.

Background

Pomegranate juice is rich in bioactive phytochemicals with antioxidant, and anti-inflammatory and cardioprotective functions. The present trial investigated the acute effects of Pomegranate juice consumption on blood pressure and markers of endothelial function.

Methods

In this single-arm study, thirteen hypertensive men aged 39-68 years were recruited. Included subjects were assigned to natural Pomegranate juice (150 ml/day) following a 12 hour fast. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and flow-mediated dilation (FMD), along with serum concentrations of C-reactive protein (CRP), intracellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), E-selectin and interleukin-6 (IL-6) were measured at baseline and 4-6 hours after Pomegranate juice consumption.

Results

Comparison of pre- vs. post-trial values revealed a significant reduction in both SBP (7%; P = 0.013) and DBP (6%; P < 0.010). However, changes in FMD (20%) as well as circulating levels of CRP, ICAM-1, VCAM-1, E-selectin, and IL-6 did not reach statistical significance (P = 0.172).

Conclusion

Pomegranate juice has promising acute hypotensive properties. Consumption of  Pomegranate juice could be considered in the context of both dietary and pharmacological interventions for hypertension.
