Some foods can prevent age-related blindness, according to scientists.
Artichokes, blueberries and pecans have been identified as some foods that can stave off blindness related to macular degeneration - a disease of the eye - thanks to their antioxidant properties.
Researchers at Brigham Young University (BYU) and Weill Medical College of Cornell University concluded that antioxidants disrupt the onset of macular degeneration and extend the lifetime of irreplaceable photoreceptors and other retinal cells.
BYU chemist Heidi Vollmer-Snarr said: "The implication is that people at risk of macular degeneration could help prevent the disease by consuming antioxidants."
Dr Paul Bernstein of the University of Utah"s Moran Eye Centre, who was not involved in the study, said the work had uncovered surprising information.
"This new knowledge suggests the possibility of interventions which could prove to be powerful ways to prevent or delay age-related macular degeneration," he added.
Other foods with antioxidant qualities include strawberries and green tea.
