There are over 50 varieties of kale and like broccoli, cauliflower and collards, kale is a descendent of the wild cabbage and has been around since ancient Roman times.
Health research on kale is providing evidence that its glucosinolates provide cancer-preventive benefits. Once digested, these glucosinolates can be converted by the body into cancer preventive compounds.
Kale's cancer preventive benefits stem from its unusual concentration of two types of antioxidants - carotenoids and flavonoids.
While it can be boiled, sautéed or bakes, the cholesterol-lowering ability of raw kale improves significantly when it is steamed.
