beneficial effects of sulforaphane-yielding broccoli sprout on cardiometabolic health: a systematic review and meta-analysis

Context: cruciferous vegetables are among the popular functional foods in disease prevention and health promotion. emerging literature suggest that sulforaphane-yielding broccoli sprouts can influence cardiometabolic diseases management. objectives: given the increasing prevalence of cardiometabolic diseases worldwide, this systematic review and meta-analysis aimed to study the cardiometabolic implications of broccoli sprout supplementation within the literature. methods: eligible literature was retrieved through pubmed and scopus up to june 2022. results: ten clinical trials investigating broccoli sprout supplementation and cardiometabolic health among human subjects were extracted for meta-analysis. the earliest study was published in 2004, and the most recent was released in 2019. seven studies included control groups for valid comparison. overall, the dietary intake of broccoli sprouts significantly reduced systolic (-10.9 mmhg; 95% confidence interval (ci): -17.0, -4.86) and diastolic (-6.95 mmhg; 95% ci: -10.6, -3.28) blood pressures. marginally significant changes were also detected in blood lipid biomarkers compared to the baseline. conclusions: our results confirm the hypotensive properties of broccoli sprout and highlight the potential sulforaphane-dependent effects of this vegetable.
