Turnipsóboth the root and the greensóare cruciferous vegetables. Although the root has a long history as a staple food, the tops are much richer in vitamins, minerals, and fiber. The green leaves are a good source of vitamins A, C, and K, as well as folate, copper, and calcium. They are high in lutein and beta-carotene, which help protect eyesight and preserve the linings of blood vessels.
Turnip greens are packed with antioxidants, and the B6 and folate help reduce levels of homocysteine in the blood, protecting the walls of blood vessels and helping prevent atherosclerosis.Nutritional Facts
