Cauliflower is a member of the mustard family (Brassicaceae) and related to cruciferous vegetables like broccoli, brussels sprouts, cabbage, collard greens and kale. Its characteristic flavor is due to the presence of sulfur compounds and their derivatives. With its nutritional profile and mild flavor, cauliflower has become popular in low carbohydrate meals, savory snacks and baked goods.
Low in fat and a good source of fiber, phenolic acids, flavonoids, carotenoids and choline, cauliflower is especially rich in antioxidant glucosinolates (sulfur-containing compounds) and their breakdown derivatives Indole-3-carbinol, sulforaphane and isothiocyanates.
