cruciferous vegetables like broccoli can potentially prevent DNA damage and metastatic cancer spread in chapter 2, activate defenses against pathogens and pollutants in chapter 5, help to prevent lymphoma in chapter 9, boost your liver detox enzymes and target breast cancer stem cells in chapter 11, and reduce the risk of prostate cancer progression in chapter 13. The component responsible for these benefits is thought to be sulforaphane, which is formed almost exclusively in cruciferous vegetables.
