Spinach contains several vitamins, too, like folate, vitamin C and vitamin K. It also has carotenoids, such as beta carotene, which your body uses to form vitamin A, and lutein, which is an antioxidant that may help to protect you from age-related macular degeneration, the major cause of blindness in the elderly.
Serving SpinachYou'll find fresh raw spinach in the produce section of your grocery store, usually near the other leafy greens. Cooked and canned spinach is available in the canned vegetable aisle and the freezer section will have frozen cooked spinach. Raw spinach works well as greens for salads (be sure to wash raw spinach, even when you buy it "pre-washed" and bagged), or you can cook the spinach and use it as a side dish. Frozen and canned spinach can be heated and served or can be used as ingredients in a variety of dishes.
