Ever heard of carotenoids? Are you familiar with what they can do for your body? Carotenoids are a phytonutrient family that represent one of the biggest groups of naturally occurring plant pigments like lutein, zeaxanthin, lycopene, and beta-carotene. Carotenoid-rich foods protect your cells from harmful free radicals, provide a source of vitamin A, keep your eyes and lungs healthy, and boost your immune system. People who smoke, drink a lot of alcohol, or don’t eat many fresh fruits and vegetables need to include more carotenoid-rich foods into their diet. Try eating sweet potatoes, collard greens, kale, papaya, carrots, Swiss chard, and asparagus.
