The Claim
Higher dietary intake of beta-carotene is associated with a 168% increased 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 the most beta-carotene in their diet have a 168% higher rate of developing neovascular age-related macular degeneration over 10 years compared to those who consume the least.

When too much beta-carotene is consumed, it breaks down in the eye and creates harmful molecules that damage the layer behind the retina. This damage causes abnormal blood vessels to grow from below the retina, leading to vision loss.
What the research says
1 studyPeople who ate more beta-carotene, like from carrots, were more likely to develop a serious eye disease called neovascular AMD over 10 years compared to those who ate less — the study found they had nearly triple the risk.
