Several species, which belong to the Brassicaceae family, represent an important part of the human diet worldwide; indeed, when regularly consumed, they have been found to exert health-promoting effects, such as a reduction in the risk of chronic diseases, particularly cardio-vascular diseases and several types of cancer . These effects have been linked to the presence in these plants of phenolics, glucosinolates, carotenoids, tocopherols, and ascorbic acid, well-known antioxidants . In particular, broccoli, white cabbage, and cauliflower are rich in glucosinolates, and, more in detail, in glucoraphanin, a molecule that is transformed by myrosinase into sulforaphane, that is a compound endowed with anticarcinogenic properties .
