Healthy dose of potassium

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 crossshaped flowers) cousin of broccoli and brussels sprouts. The difference is in the amount (or absence) of chlorophyll present during the vegetables growth.
