Arugula is one of the brassica family vegetables along with broccoli, cauliflower and cabbage. These vegetables are high in fiber and antioxidants, and also rich in glucosinolates, which studies show may reduce the risk of developing lung, prostate, breast and pancreatic cancer.
Half cup of arugula contains 10.9 micrograms of vitamin K. Vitamin K is needed for bone health; it is needed for the absorption of calcium into the bones and teeth. Three cups of arugula daily will supply you with 100 percent of your bodies need of vitamin K.
Arugula contains indole-3-carbinol and isothiocyanates, which have been shown to suppress the production of inflammation in the body.
Arugula is high in most B vitamins but contains especially high amounts of folate. In high-functioning older adults, low levels of folate have been shown to be a risk factor for cognitive decline.
