Spinach is good for more than your eyes. Your body needs iron in order to transport oxygen from your lungs to all the cells in your body, and vitamin K is necessary for normal blood clotting. Lutein is an antioxidant and may also help prevent or slow down atherosclerosis, the thickening of arteries, which is a major risk for cardiovascular disease.
You can eat raw spinach leaves in place of lettuce in salads and sandwiches, or serve spinach as a side dish or incorporate it into other recipes.
