“A superfood food that many people don’t know about is Mexican papaya,” Bohland says. This delicious tropical food is a source of a lot of antioxidants, phytonutrients, vitamins, and minerals that protect your eyes, skin, and relieve digestion problems. A study suggests that enough of the zeaxanthin and lutein in the papaya decreases the risk of developing age-related macular degeneration (ARMD), a common cause of blindness in America, according to the Centers for Disease Control and Prevention.
