Leafy green vegetables like spinach and kale pack a healthy dose of lutein, a substance that promotes eye health. Lutein is a pigment found in plants that has been shown to curb the effects of cataracts, a condition that decreases your vision. Cooking these greens effectively helps your body better absorb the lutein in these lush green leaves. Add spinach to your soups, stir-fry dishes and smoothies to stay protected.
