Kale is a form of cabbage and related to broccoli, cauliflower and Brussels sprouts. It is very low in calories and contains more nutrients than most other greens. Kale is an excellent source of vitamin K, which is essential for bone and blood health, and helps by mediating coagulation and anticoagulation. Sulforaphane is a chemical found in kale and also sprouts and broccoli. A study published in Drug Discovery Today found that sulforaphane may help stop breast cancer cells from growing. The University of Texas conducted a study and found that a diet rich in kale may prevent bladder cancer by up to 29%. Kale may also help ovarian cancer too. The Nurse’s Health Study observed that women whose diets provided the most kaempferol, a flavonoid found in kale, had a 40% reduction in risk of ovarian cancer. By supplying the body with plenty of calcium, copper and manganese, kale may help absorb iron and prevent bone loss.
