 Brightly colored vegetables, carrots, squash, broccoli, all the peppers, sweet potatoes, tomatoes, and kale are other tasty sources. And for those of you with a sweet tooth, good news. Honey, brown sugar, and maple syrup, in addition to fruits like blueberries, cantaloupe, peaches, and strawberries, also contain significant levels of antioxidants.
