Turnips are root vegetables belonging to the Brassicaceae family, which also includes broccoli, Brussels sprouts, cabbage, and kale. They are grown primarily for their bulbous roots, although their leaves, known as turnip greens, are also edible and highly nutritious. They are a good source of Vitamin C, fiber, and also contain some key minerals such as potassium and calcium. Turnip greens are particularly rich in vitamins A, C, and K, and are an excellent source of calcium, according to healthline.com.
