Can Cherries Lower Blood Pressure?
Based on the highest quality evidence, cherries do not significantly lower blood pressure and should not be relied upon as a blood pressure management strategy. 1
Evidence Assessment
The most recent and comprehensive systematic review and meta-analysis from 2022 specifically examined cherry consumption (both tart and sweet) and blood pressure outcomes across 7 randomized controlled trials with 201 participants 1. This analysis found no significant effect on either systolic or diastolic blood pressure.
Conflicting Evidence Explained
While some individual studies suggest potential benefits:
- A 2021 study in metabolic syndrome patients showed 24-hour ambulatory blood pressure reductions with Montmorency tart cherry juice 2
- A 2021 meta-analysis of berries (including cherries) found cherry juice reduced systolic BP by 3.11 mmHg 3
- A 2023 meta-analysis showed no blood pressure effects overall 4
However, these findings are inconsistent, involve small sample sizes, and the 2022 meta-analysis 1 represents the most direct and comprehensive assessment of this specific question.
Evidence-Based Blood Pressure Management
Major hypertension guidelines consistently recommend proven dietary interventions that do lower blood pressure 5, 6, 7:
Effective Dietary Strategies (in order of evidence strength):
DASH Diet - Reduces BP by 5.5/3.0 mmHg overall and 11.4/5.5 mmHg in hypertensives 8, 6, 9
- Emphasizes fruits, vegetables, low-fat dairy, whole grains
- Reduces saturated fat, red meat, sweets
Sodium Reduction - Target 2000 mg/day (87 mmol) 8, 6
- Reduces BP by approximately 5.1/2.7 mmHg 10
Weight Loss - Approximately 1 mm Hg reduction per kg lost 6, 7
Potassium-Enriched Salt Substitutes - Reduce BP by 5/1.5 mmHg 7
Moderate Alcohol Consumption - Limit to 2 drinks/day (men) or 1 drink/day (women) 5, 6
Regular Physical Activity - 30-60 minutes moderate exercise 4-7 days/week 8, 11
Clinical Bottom Line
While cherries are nutritious and may have anti-inflammatory properties 4, they lack sufficient evidence for blood pressure reduction. Patients seeking dietary approaches to lower blood pressure should focus on the DASH eating pattern, sodium reduction, and weight management—interventions with robust, consistent evidence from large-scale trials demonstrating clinically meaningful blood pressure reductions and cardiovascular risk reduction 6, 7.
Common Pitfall to Avoid
Do not recommend cherries or cherry juice as a blood pressure intervention based on preliminary or single studies. The aggregate evidence does not support this use, and patients may delay or avoid proven interventions if they believe cherries are sufficient.
