Kudos for Kale
Like its cousins in the Brassica family—broccoli, Brussels sprouts, cabbage and collards—kale is a low-calorie, nutrient-dense powerhouse of antioxidants, including vitamins A and C. Per calorie, kale contains more iron than beef and more calcium than milk, and it is better absorbed by the body than most dairy products. A single serving (about one cup, chopped) provides 5 percent of the recommended daily intake of fiber, plus two grams of protein. The versatile veggie—it is tasty steamed, braised or baked—is also a rich source of both omega-3 and omega-6 essential fatty acids.
Best of all, kale is a “green” green, high on the sustainability scale. Growing one pound of kale uses about 23 gallons of water; raising a pound of beef necessitates more than 2,400.
