Broccoli is a cruciferous vegetable that belongs to the cabbage family, which also includes arugula, cauliflower, collards, bok choy, kale, mustard greens, radishes, turnips, watercress, rutabaga, and brussels sprouts.
About 2 decades ago, researchers first suggested a possible link between diets high in cruciferous vegetables (a group of plants including cauliflower, cabbage, broccoli, and Brussels sprouts)) and a lower risk of cancer. However, it was not until the 1990s that certain chemicals found in broccoli were identified as possible cancer-preventing compounds. In 1997, a study was published that noted broccoli sprouts had higher levels of one of these compounds than mature broccoli.
Broccoli contain a class of potent anti-carcinogens (cancer-combating agents) called isothiocyanates. These compounds block many cancer-causing agents in a wide variety of cancers. They also detoxify potential carcinogens such as environmental toxins. It’s an excellent source of fiber, vitamin C, beta-carotene and many other carotenoids and calcium. And each of these micronutrients supports overall health and helps counter cancer.
