Did you know leafy greens are a good source of calcium? Maybe you love salad, or can’t remember the last time you ate a leafy vegetable. Either way, greens are an important part of a healthy diet! Dark leafy greens such as kale, spinach, collards, and salad greens contain essential vitamins such as vitamin K, C, A, and E and are also high in magnesium, potassium, iron and fiber.
