Red cabbage is a nutrient-rich, cruciferous, or Brassica vegetable that’s related to cauliflower and kale. It’s sometimes called purple cabbage since its leaves are a dark purple-reddish color. Red cabbage typically is a little smaller and denser than green cabbage, and has a more peppery taste.
This variety of cabbage gets its purple-reddish color from the flavonoid anthocyanin and the acidity level of the soil where it’s grown. Like most colorful vegetables, it’s highly nutritious, low in fat and calories, and has numerous health benefits.
