Consuming foods such as dark green leafy vegetables rich in lutein and zeaxanthin may reduce the risk of late-stage age-related macular degeneration (AMD), according to a new Chinese review of 6 prior studies.
Lutein, also found in egg yolks, has been associated with benefits for eye health since 1994. In the new analysis, both carotenoids were associated with a 26% reduction in the risk of late-stage AMD.
The research found only a non-significant 4% reduction in risk of early-stage AMD, however. Noting that only a few studies have examined the association between the carotenoids and AMD risk, scientists called for further research to provide “definitive conclusions.” – British Journal of Nutrition
