The Claim
Higher dietary intake of bioavailable lutein and zeaxanthin is associated with a 41% lower risk of developing advanced age-related macular degeneration over 20–26 years of follow-up in adults aged 50 and older.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adults aged 50 and older who consume more bioavailable lutein and zeaxanthin through their diet have a 41% lower incidence of advanced age-related macular degeneration over 20 to 26 years.
See the scientific wording
Higher dietary intake of bioavailable lutein and zeaxanthin is associated with a 41% lower risk of developing advanced age-related macular degeneration over 20–26 years of follow-up in adults aged 50 and older, based on repeated dietary assessments and validated plasma carotenoid predictions, suggesting these carotenoids may play a protective role in retinal health during aging.
Lutein and zeaxanthin from food enter the bloodstream, travel to the back of the eye, and build up in the central part of the retina. There, they block harmful blue light and neutralize damaging molecules created by light and oxygen. This protects the cells that support vision and prevents them from breaking down over time, stopping the disease from getting worse.
What the research says
1 studyPeople who ate more spinach, kale, and other colorful veggies over many years had about 40% less chance of getting the worst kind of age-related vision loss, according to a big, long-term study. This suggests these foods help protect the eyes as we age.
