Ancient healers have long used remedies produced from plants in the crucifer family. Kale has been demonstrated to be effective in the treatment of infectious diseases through the discovery and characterization of antimicrobials present in these plants.
There is convincing experimental data proving their role of Kale in the prevention of degenerative diseases.
Subsequent epidemiological studies revealed that some cancers, especially colon cancer, are less frequent in individuals who regularly consume vegetables such as Kale. A pioneering study by Wattenberg identified sulfur compounds present in cruciferous vegetables as protectors against cancer.
