Key result
Daily cucumber supplementation lowers systolic and diastolic blood pressure compared to baseline in older adults.
Why the study?
Hypertension and obesity are increasingly common in older adults, raising cardiovascular and diabetes risk, and dietary supplementation with antioxidant- and mineral-rich vegetables may beneficially affect BP and anthropometric indices.
Does daily fresh cucumber supplementation reduce blood pressure and anthropometric indices in healthy older adults?
Does daily fresh cucumber supplementation reduce blood pressure and anthropometric indices in healthy older adults?
Four weeks of daily fresh cucumber consumption significantly lowered systolic and diastolic blood pressure in healthy older adults without significantly altering anthropometric indices.

May lower BP in older adults as a dietary option; leaves open confirmation in randomized trials.
Hypertension and obesity are becoming common among the older adults and this increases the risk of several non-communicable diseases such as cardiovascular diseases and diabetes mellitus. Dietary supplementation with vegetables rich in antioxidant-rich compounds and minerals may have a beneficial effect on the blood pressure (BP) and anthropometric indices. Consequently, the objective of this paper was to determine the impact of cucumber supplementation on blood pressure (BP) and anthropometric indices in healthy older adults in Nnewi, Anambra State, Nigeria with Thirty (30) participants who received 400 g ±10 g of fresh whole cucumbers every day for a total of four (4) weeks (28 days) and were required to eat the entire cucumber every day before their daily breakfast. Results showed the mean SBP (P=0.004) and DBP (P=0.001) levels were significantly decreased whereas, BMI (p=0.088), WC (p=0.097) and WHR (p=0.136) did not differ significantly after cucumber supplementation compared to baseline levels. This study has shown the BP lowering effect (hypotensive effect) of Cucumis sativus (cucumber) consumption in older adults and could be of importance in the prevention and therapeutic management of hypertension.

Onah et al. (2025) studied Healthy older adults (blood pressure and anthropometric indices) (n=30). Fresh whole cucumber (Cucumis sativus) supplementation vs. Baseline levels (pre-supplementation) was evaluated on Blood pressure (SBP and DBP) and anthropometric indices (BMI, WC, WHR) (p=0.004 for SBP; 0.001 for DBP). Daily cucumber supplementation (400 g) for 4 weeks decreased mean SBP and DBP compared to baseline in healthy older adults.
