Cauliflower is a white, flowering vegetable belonging to the cruciferous family - which also includes broccoli, Brussels sprouts, collard greens, cabbage, and bok choy.
Cauliflower is very low in calories (26 calories/100 g), and virtually no fat or cholesterol and it is super rich in dietary fiber (2 g/100 g). Cauliflower florets apparently contain several anti-cancer phytochemicals like sulforaphane and plant sterols such as indole-3-carbinol which appears to function as an anti-estrogen agent. Together these compounds have proven benefits against prostate, breast, cervical, colon, ovarian cancers by virtue of their cancer cell growth inhibition, cytotoxic effects on cancer cells. One Canadian study found that eating a half cup of cauliflower per day reduced the risk of prostate cancer by 52%.
