The Claim
Higher dietary intake of lutein and zeaxanthin is associated with a 65% reduced risk of incident neovascular age-related macular degeneration in adults aged 49 and older when comparing the highest versus lowest tertiles of intake over a 10-year follow-up period.
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 49 and older who consume more lutein and zeaxanthin in their diet have a 65% lower incidence of neovascular age-related macular degeneration compared to those with the lowest intake, based on a 10-year observation period.
See the scientific wording
Higher dietary intake of lutein and zeaxanthin is associated with a 65% reduced risk of incident neovascular age-related macular degeneration in adults aged 49 and older, based on comparison of the highest versus lowest tertiles of intake over a 10-year follow-up period, suggesting a potential role for these carotenoids in long-term retinal health.
Lutein and zeaxanthin collect in the center of the retina, where they block harmful blue light and neutralize damaging molecules made by light and oxygen, preventing cell damage that leads to abnormal blood vessel growth.
What the research says
1 studyPeople who ate more leafy greens and eggs—rich in lutein and zeaxanthin—were much less likely to develop a serious eye disease over 10 years than those who ate less. The study found a clear link between eating more of these nutrients and better eye health.
