Chung-Jung Chiu, PhD, of the Laboratory for Nutrition and Vision Research, Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, led this new analysis of Age-Related Eye Disease Study (AREDS) data.
One involves taking the high daily doses of vitamin C (500 mg), vitamin E (400 IU), beta-carotene (25,000 IU), and zinc (80 mg) that were used in the first Age-Related Eye Disease Study (AREDS), a clinical trial that the National Eye Institute completed in 2001.
The long-term Age-Related Eye Disease Study (AREDS), conducted by the National Eye Institute, found that supplementing the anti-oxidants beta-carotene, vitamin C, vitamin E, and the mineral zinc reduced the risk of developing advanced states of macular degeneration in more than 4,700 high-risk patients aged 55 to 80 who were enrolled in the study.
In the latest study, scientists involved in the Carotenoids in Age-Related Eye Disease Study (Careds) recruited a number of older women who had either high or low dietary intakes of lutein and zeaxanthin.
To illustrate the complexity of researching dietary effects on vision, Kurinij compares randomized clinical trial results from the NEI's Age-Related Eye Disease Study to cataract studies conducted in Linxian, China.
Since he didn't offer any preventative measures, I read everything that I could get my hands on, which is how I learned of Harvard's Age-Related Eye Disease Study (AREDS) and other studies on the relationship between eating large amounts of greens and reducing the risk of MD.
Findings from the NEI-sponsored Age-Related Eye Disease Study (AREDS) showed that high levels of antioxidants and zinc has no significant effect on the development or progression of cataract.
