Arugula provides a healthy diet, but contains few calories. These are green leaves with a spicy taste. Arugula leaves are rich in nutrients, including beta-carotene, vitamin C, folic acid and magnesium, which are key to the proper functioning of body systems.

Although arugula is not like broccoli, it is a cruciferous vegetable with many of the same health benefits as broccoli and Brussels sprouts. Arugula is relatively inexpensive, and it's easy to find pre-packaged at most grocery stores. It is also easy to grow at home in the garden on the windowsill or outdoors.
