Nutritional Analysis of Purple Vegetables
Purple Cabbage: King of Antioxidants
As a star of the cruciferous family, purple cabbage contains 35 mg of anthocyanins per 100 grams, which is 6 times more than ordinary cabbage. Its vitamin C content is equivalent to that of citrus fruits and ranks at the top of the vegetable vitamin C list along with broccoli. It is especially recommended to eat it cold to retain water-soluble vitamins to the maximum extent.
Purple Onion: Vascular Cleanser

Purple Eggplant: Treasure of Dietary Fiber
