Broccoli

Broccoli greens are young broccoli plants that are rich in glucoraphanin, a precursor of sulforaphane. Preclinical studies suggest that sulforaphane, has anticancer effects against prostate, breast, and urinary cancers. 1 ounce of broccoli greens has the same level of sulforaphane as 1.5 pounds of mature broccoli. Less is more!
