Summary
This study looked at whether eating corn rich in zeaxanthin (a natural pigment) could increase the density of the macular pigment in the eye, which may help prevent age-related macular degeneration (AMD), a leading cause of blindness. Nine healthy volunteers aged 20-35 ate a daily serving of this corn for 10 weeks. The goal was to measure changes in macular pigment density and blood zeaxanthin levels.
