Cauliflower is a vegetable used for lowers blood pressure (cruciferous rct). NutriDex grades the human evidence as Moderate. Cauliflower is a glucosinolate-rich cruciferous vegetable whose strongest human evidence is cardiometabolic: a randomized crossover trial found ~300 g/day of cruciferous vegetables lowered 24-h systolic blood pressure by 2.5 mmHg versus root/squash vegetables, and large prospective cohorts link higher cruciferous intake to lower cardiovascular and all-cause mortality. Meta-analyses of observational studies show modest inverse associations with colorectal cancer and type 2 diabetes risk, though dose-response signals are weaker. Its signature bioactive, sulforaphane, has shown promising but still preliminary effects on glycemic control and behavioral outcomes in small RCTs.
Purported Benefits
✓Lowers blood pressure (cruciferous RCT)
✓Linked to lower cardiovascular and all-cause mortality
✓Inverse association with colorectal cancer
✓High vitamin C, very low calorie
✓Supports glycemic control
Dosing & Compounds
Typical Dose
Standard serving: 1 cup chopped, raw (107 g). Eat whole (with skin where edible); favour whole fruit over juice.
Raw cruciferous vegetables contain goitrogens that may modestly affect thyroid function in iodine-deficient individuals at very high intakes; vitamin K (~17 ug/cup) is relevant for those on warfarin; high fiber and raffinose-family oligosaccharides (FODMAPs) can cause gas/bloating in sensitive or IBS individuals. Generally very safe as food. Educational only — always check with your doctor or pharmacist before combining Cauliflower with any medicine.
Cauliflower is most often taken for Lowers blood pressure (cruciferous RCT), Linked to lower cardiovascular and all-cause mortality, Inverse association with colorectal cancer, High vitamin C, very low calorie. A low-carb cruciferous all-rounder: half a day's vitamin C with glucosinolate-derived sulforaphane.
