First prized by the court of King Louis XIV, cauliflower provides a royal health boost to everyone's diet. This versatile veggie is not only low in calories, it's also full of vitamins and minerals. One cup of raw cauliflower is high in the antioxidant vitamin C -- required for the growth and repair of tissues in all parts of your body, and necessary for the formation of the important protein collagen, used to make skin, scar tissue, tendons, ligaments, and blood vessels.
Cauliflower also offers a healthy dose of potassium, fiber, and folic acid and contains a sulfur compound called isothiocyanate that protects health and prevents disease. Not all cauliflower is white. You can find green and orange varieties of this cruciferous (named for the cross-shaped flowers) cousin of broccoli and Brussels sprouts. The difference is in the amount (or absence) of chlorophyll present during the vegetable's growth.
All vegetables in the cruciferous family -- kale, cabbage, broccoli, and Brussels sprouts -- are packed with vitamin C and potassium."
