Carrots are bursting with health-promoting antioxidants and vital nutrients needed for good eye health and vision. Orange carrots are packed with beta-carotene, which is a precursor to vitamin A. We need this important vitamin for healthy skin and mucous membranes and for a strong immune system. Carrots also provide plenty of lutein, a potent antioxidant that helps protect the eyes from age-related macular degeneration.
