Association between late age-related macular degeneration and dietary intake of copper, iron, zinc and selenium: a 2005–2008 NHANES cross-sectional observational study
Our findings suggest a higher dietary copper intake may be associated with a reduced risk of late AMD, with the protective effect remaining significant among individuals aged 70-85 years. While no significant association was identified between dietary intake of iron, zinc, selenium and AMD after adjusting for confounding factors. Further research is warranted to elucidate the mechanism underlying the relationship.
