Broccoli綠花椰菜
Signature ingredient: Vitamin C — B-grade evidence (Immune Function, ~99% of the studied dose per serving)
Standard nutrients per USDA FoodData Central · phytochemicals (lutein / K2 / sulforaphane etc.) are literature estimates, varying by variety and processing
S / A … ingredient evidence tier (tap for the claim) | bar = how much of the studied dose one serving of Broccoli gives you
Meaningful intake one serving delivers a real fraction of the studied dose
Vitamin C
89mg · 99% DV · High amount of vitamin C
B Immune Function →
＋ Scurvy A・Wound Healing A
≈ 99% of studied dose
Sulforaphane
15mg · Low in mature broccoli; broccoli sprouts are 10-100x higher
C Cancer Prevention →
＋ Liver Health C・Oxidative Stress C
≈ 75% of studied dose
High amount, but caveats a big number ≠ effective
Vitamin K
102ug · 85% DV
B Osteoporosis →
＋ Hemorrhage Prevention Newborn A・Vascular Calcification C
Mostly K1; bone research uses K2
⚠Wrong form
Trace contribution far below the studied dose — not a therapeutic source
Why this page doesn't claim "Broccoli works"
Whole foods almost never have RCTs — the evidence sits on the ingredients. So this page does one honest thing: it lists which graded ingredients Broccoli contains, how much, and how far that is from the studied dose. It makes no efficacy claim about Broccoli itself.
Bottom line: Broccoli's best assets are vitamin C (high amount) and sulforaphane (low in mature broccoli, 10-100x higher in sprouts); its vitamin K is K1, not the form used in bone research.
