Spinach, kale and other green vegetables contain the phytonutrients lutein and zeaxanthin, which have been linked to eye health as well as protection against heart disease and some forms of cancer. Broccoli and other cruciferous vegetables are rich in indoles, compounds with possible anti-cancer properties. Be sure to include green on your shopping list to get the full range of vitamins, minerals, fiber and phytonutrients you need for better health.
