The Claim
Higher total dietary zinc intake is associated with a 44% reduced risk of any age-related macular degeneration and a 46% reduced risk of early age-related macular degeneration in adults aged 49 and older when comparing the highest decile of intake to the rest of the population 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 the highest amounts of zinc in their diet have a 44% lower risk of developing any form of age-related macular degeneration and a 46% lower risk of early-stage age-related macular degeneration compared to those with lower zinc intake over a 10-year period.
See the scientific wording
Higher total dietary zinc intake is associated with a 44% reduced risk of any age-related macular degeneration and a 46% reduced risk of early AMD in adults aged 49 and older, based on comparison of the highest decile versus the rest of the population over a 10-year follow-up period.
Zinc helps protect the back of the eye by keeping cells in the retina healthy and stopping harmful molecules from damaging them, which prevents early signs of vision loss.
What the research says
1 studyPeople who ate more zinc-rich foods over 10 years were about half as likely to develop early signs of eye disease compared to those who ate less zinc. The study found this link clearly and reliably.
