The Effect of Cranberry Consumption on Blood Pressure: A Systematic Review and Meta‐Analysis of Randomized Controlled Trials

To evaluate the effect of cranberry consumption on systolic and diastolic blood pressure through a systematic review and meta-analysis.
Performed a systematic review of randomized controlled trials
Analyzed data to compare blood pressure changes before and after cranberry consumption
Cranberry consumption showed no significant effect on systolic blood pressure (SBP) and diastolic blood pressure (DBP)
Findings indicate limited benefits of cranberry in managing blood pressure

This systematic review and meta-analysis suggest that cranberry consumption was not effective in managing SBP and DBP.
