Contains Compounds That May Prevent Certain Types of Cancer
Because watercress is high in phytochemicals, it may reduce your risk of developing certain types of cancer.
Watercress and other cruciferous vegetables contain glucosinolates, which are activated to compounds called isothiocyanates when they’re cut with a knife or chewed.
Isothiocyanates include chemicals such as sulforaphane and phenethyl isothiocyanate (PEITC).
