Arugula greens are rich sources of certain phytochemicals such as indoles, thiocyanates, sulforaphane, and iso­thiocyanates. Together, these compounds have been found to counter the carcinogenic effects of estrogen and thus may offer protection against prostate, breast, cervical, colon, ovarian cancers by their cancer-cell growth inhibition, cytotoxic effects on cancer cells.
Fresh salad rocket is one of the greens rich in folates. When given to the anticipant mothers during their conception time, folate may help prevent neural tube defects in the newborns.
Fresh rocket leaves contain healthy levels of vitamin-C. Vitamin-C is a powerful, natural anti-oxidant. Foods rich in this vitamin help the human body protect from scurvy disease, develop resistance against infectious agents (boosts immunity), and scavenge harmful, pro-inflammatory free radicals from the body.

Celery and celery seeds have anti-inflammatory compounds that can offer protection against inflammation in the body.
And then there’s the high water content of celery plus generous amounts of soluble and insoluble fiber. All of those support a healthy digestive tract and keep you regular.
Celery is loaded with antioxidants. These include well-known varieties such as flavonoids and vitamin C, as well as lunularin and bergapten. These and other antioxidants help to prevent the oxidative stress that contributes to cancer.
