The Claim
Higher dietary intake of total carotenoids is associated with a 35% lower risk of advanced age-related macular degeneration over a 20-year period in adults aged 50 and older.
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 50 and older who consume more carotenoid-rich foods have a 35% lower risk of developing advanced age-related macular degeneration over 20 years compared to those who consume less.
See the scientific wording
Higher intake of total carotenoids from diet is associated with a 35% lower risk of advanced age-related macular degeneration over two decades in adults aged 50 and older, indicating that a diverse intake of carotenoid-rich foods may offer greater protection than isolated nutrients.
Eating a variety of colorful fruits and vegetables delivers carotenoids into the bloodstream, which travel to the back of the eye. Some carotenoids settle in the central part of the retina and block harmful blue light while neutralizing damaging molecules made by light and oxygen. Other carotenoids settle in nearby tissues and protect the cells that support the retina. Together, this reduces long-term damage that leads to severe vision loss.
What the research says
1 studyPeople who ate lots of colorful fruits and vegetables over many years had about a third less risk of severe vision loss from AMD, and eating a variety of these foods was more helpful than just one type.
