Glucosinolates

Both broccoli and cauliflower contain glucosinolates compounds containing sulfer that are found only in cruciferous vegetables. Eating glucosinolates might help lower your risk of cancer, according to the Linus Pauling Institute. While the mechanisms by which these compounds prevent cancer is not yet fully understood, the compounds might help remove or neutralize carcinogens or affect your bodys hormone levels to prevent hormonerelated cancers, or they might simply change how your cells grow to prevent the uncontrolled growth seen in cancer. The Linus Pauling Institute recommends eating at least five weekly servings of cruciferous vegetables, including broccoli and cauliflower, to reap their cancerfighting benefits.
