Radicchio can help promote better eye health

Although radicchio contains very low amounts of vitamin A, it possesses a high amount of phenolic flavonoid antioxidants such as zeaxanthin and lutein. One hundred grams of the leaves provide 8832 micrograms of these compounds. Zeaxanthin concentrates mainly in the central retina in the eyes. Together with lutein, it helps protect eyes from agerelated macular disease by filtering harmful ultraviolet rays.
