When it comes to grown-up greens, kale is deserving of its superfood epithet. It absolutely smashes its competitors in terms of lutein, a potent antioxidant shown to protect eyesight, and leads the way with respect to beta-carotene and vitamin C. As a member of the Brassica family along with broccoli and Brussels sprouts, kale also brings sulforaphane to the table, a phytonutrient shown to have cancer-fighting properties. Steaming or sautéing kale will mellow this all-star’s bitter flavor.
Eat outside the bowl: For a power-packed creamy smoothie that doesn’t taste like a salad, combine 1 1/2 cups coconut water, 1 ripe avocado, 4 kale leaves, 1 celery stalk, 1 cup frozen mango cubes, 2 tablespoons ground flaxseed, 1 tablespoon honey, and 1 teaspoon fresh ginger in a blender until smooth. Or when you're on the go, stop by Jamba Juice for a Garden Medley, a blend of apple juice, carrot juice, baby spinach, chard, baby kale, and chia seeds.
