Cauliflowers are useful against disorders of the Immune System and the Digestive System
They are good for disorders such as stress, cancer protection and low immunity. Like other members of the cruciferous family of vegetables they have been shown to have protective powers against cancer. (Other crucifers include brussels sprouts, kale, radishes, horseradish, cabbage, spring greens, turnips, brocolli and kale).
Cauliflowers are rich in carotenoids, including betacarotene, a strong cancer protector and have some Iron, Vitamin C and folate which also help anaemia, protect against birth defects, and boost energy, specially if you eat the young leaves closest to the florets. There is also a high level of chemicals called glucosinolates, a cancer protective agent particularly effective against colon and breast cancers.
