“Lutein and zeaxanthin are two antioxidants found in egg yolks that may help prevent macular degeneration, a leading cause of age-related blindness,” Kanter said. “The two nutrients are part of the carotenoid family (like beta-carotene in carrots).” The American Optometric Association notes the presence of these anti-oxidants in eggs.
In a study published in The American Journal of Clinical Nutrition, 11 men and women supplemented their diets with 1.3 egg yolks per day for 4.5 weeks. Participants’ levels of lutein increased by 28-50 percent, and their levels of zeaxanthin increased by 114-142 percent.
