Cabbages are leafy plants of the Brassica oleracea species. Multiple cultivars exist, ranging in colours, leaf patterns, and flavor. The generic term cabbage most commonly applies to green cabbage. See: Cabbage, green
Individual cabbage cultivars have slightly different contents of various micronutrients and specific plant compounds such as glucosinolates. See: Cabbage, green; Cabbage, red; Cabbage, savoy
Cooking reduces glucosinolate and isothiocyanate content of cabbage, with boiling causing the greatest loss and steaming causing the least.
