Why are dark leafy greens healthy?

Dark leafy greens carry a serious nutritious punch. They provide you with vitamins, minerals and phytonutrients. As a general rule, the darker green the better. For example, spinach provides more of a nutritional benefit than iceberg lettuce.
It's almost impossible to meet your nutritional needs without eating dark leafy greens, such as spinach, romaine lettuce, collard greens, kale, and chard. They're huge sources of fiber, vitamins C and K, folic acid (a B vitamin that guards your heart and memory and fights birth defects), lutein (a vision protector), and four essential minerals: calcium, magnesium, iron, and potassium. Leafy greens also deliver a hefty supply of anti-aging vitamin A, which supports skin-cell turnover to help keep your skin soft and supple. Go for two servings a day (e.g., 1 cup cooked greens or 2 cups raw greens). The darker, the better.

Leafy greens are healthy because they are loaded with nutrients. Dark leafy vegetables like spinach, salad greens, collards, kale, radicchio and watercress grow in tight or loose heads or individually on stems. A few dark leafy greens are actually the tops of root vegetables like turnips or beets. Most greens are excellent sources of beta carotene and vitamin C. They are also good sources of folacin and fiber and depending on the specific green can be a good source of calcium and iron. All dark leafy greens are low in calories.
