Brussels sprouts (Brassica oleracea Gemmifera Group) have been researched for their potential benefits in managing aspects of Metabolic Syndrome, a cluster of conditions including insulin resistance, dyslipidemia, hypertension, and central obesity. The scientific rationale for using Brussels sprouts in this context primarily centers on their rich content of bioactive compounds such as glucosinolates, fiber, vitamins C and K, and various antioxidants.

Some experimental and small-scale human studies suggest that diets high in cruciferous vegetables, including Brussels sprouts, are associated with improved markers of metabolic health. The high fiber content may help regulate blood glucose and improve insulin sensitivity, while the antioxidants may reduce systemic inflammation, a key driver of metabolic syndrome. Additionally, certain phytochemicals in Brussels sprouts, such as sulforaphane and other isothiocyanates, have been shown in laboratory studies to modulate lipid metabolism and may have beneficial effects on blood pressure and cardiovascular risk factors.

However, while population-based studies support a general association between cruciferous vegetable intake and reduced risk of metabolic disease, direct evidence from randomized controlled trials specifically testing Brussels sprouts for the treatment or prevention of metabolic syndrome is lacking. Most available evidence is indirect or extrapolated from studies of broader dietary patterns. Therefore, while there is some scientific basis and plausible mechanisms, the strength of evidence is currently limited, and more targeted clinical research is needed.
