The Effectiveness of Tomato Juice Consumption in Reducing Blood Pressure Among Postmenopausal Women

SMSirajul MunaAAsmanidar

Key Result

Daily consumption of 250 mL of tomato juice for four consecutive days significantly reduced mean systolic blood pressure by 12.5 mmHg and diastolic blood pressure by 15.0 mmHg in postmenopausal women.

Key Points

  • The study evaluates how effective tomato juice consumption is in lowering blood pressure among postmenopausal women with hypertension.
  • Conducted a pre-experimental study with a one-group pretest–posttest design.
  • Involved 22 postmenopausal women with mild to moderate hypertension.
  • Administered 250 mL of tomato juice daily for four consecutive days.
  • Measured blood pressure before and after the intervention and analyzed data using the Wilcoxon Signed-Rank Test.
  • Mean systolic blood pressure reduced by 12.5 mmHg from 156.25 mmHg to 143.75 mmHg.
  • Mean diastolic blood pressure decreased by 15.0 mmHg from 98.75 mmHg to 83.75 mmHg.
  • Statistical analysis revealed significant reductions with p-values of 0.005 for systolic and 0.001 for diastolic blood pressure.

Structured PICO

Does daily tomato juice consumption reduce systolic and diastolic blood pressure in postmenopausal women with mild to moderate hypertension?

P
Population
22 postmenopausal women (aged 45-60 years, ceased menstruation for at least 12 months) with mild to moderate hypertension (systolic blood pressure 140-160 mmHg or diastolic blood pressure 90-100 mmHg) not currently taking antihypertensive medications, residing in Banda Aceh City, Indonesia. Exclusions: history of chronic diseases (diabetes mellitus, kidney failure, heart disease), tomato allergy, or non-compliance.
I
Intervention
250 mL of tomato juice (prepared using 200 grams of fresh local tomatoes, 5 grams of granulated sugar, and 50 ml of boiled water) administered orally once daily for four consecutive days.
O
Outcome
Reduction in systolic and diastolic blood pressure measured after the fourth day of intervention.surrogate

Daily consumption of tomato juice for four consecutive days significantly reduced both systolic and diastolic blood pressure in postmenopausal women with mild to moderate hypertension.

Main Result

Effect estimate: Mean difference -12.5 mmHg

Absolute Event Rate: 143.75% vs 156.25%

p-value: p=0.005

Limitations

  • Lack of a control group (one-group pretest-posttest design)
  • Small sample size (n=22)
  • Short intervention duration of only four days

Abstract

Introduction: Hypertension is a major health problem among postmenopausal women, largely attributable to the decline in estrogen levels, which results in the loss of estrogen’s cardioprotective effects and leads to increased vascular stiffness and elevated blood pressure. Although pharmacological therapy remains the primary approach for hypertension management, long-term use of antihypertensive medications is often associated with adverse effects and reduced treatment adherence. Therefore, safe and accessible non-pharmacological interventions are needed. Tomato juice, which is rich in bioactive compounds such as lycopene and potassium, has been suggested as a potential dietary intervention for blood pressure control.Objective: This study aimed to evaluate the effectiveness of tomato juice consumption in reducing systolic and diastolic blood pressure among postmenopausal women with hypertension.Methods: A pre-experimental study with a one-group pretest–posttest design was conducted in the service area of a primary healthcare center in Banda Aceh, Indonesia. The study involved 22 postmenopausal women with mild to moderate hypertension who were selected using purposive sampling. The intervention consisted of daily administration of 250 mL of tomato juice for four consecutive days. Blood pressure was measured before and after the intervention, and data were analyzed using the Wilcoxon Signed-Rank Test.Results: The results demonstrated a significant reduction in mean systolic blood pressure by 12.5 mmHg, from 156.25 mmHg to 143.75 mmHg, and in mean diastolic blood pressure by 15.0 mmHg, from 98.75 mmHg to 83.75 mmHg. Statistical analysis indicated that these reductions were significant, with p-values of 0.005 for systolic blood pressure and 0.001 for diastolic blood pressure (p < 0.05).Conclusion: Regular consumption of tomato juice for four consecutive days was effective in significantly reducing both systolic and diastolic blood pressure among postmenopausal women. This intervention may serve as a safe and practical non-pharmacological strategy for hypertension management in postmenopausal populations.

Muna et al. (2026) studied Mild to moderate hypertension in postmenopausal women (n=22). Tomato juice vs. Baseline (pre-intervention) was evaluated on Mean systolic blood pressure (Mean difference -12.5 mmHg, p=0.005). Daily consumption of 250 mL of tomato juice for four consecutive days significantly reduced mean systolic blood pressure by 12.5 mmHg and diastolic blood pressure by 15.0 mmHg in postmenopausal women.
