Corn could offer a solution to vision problems that many people face as they age, according to a new study from the University of Guelph.
Researchers at Guelph bred a new strain of corn to contain the antioxidants lutein and zeaxanthin, which protect eyes. The corn was fed to chickens that laid eggs rich in these helpful carotenoids. The researchers speculated that the carotenoids in the egg yolk would be more concentrated and absorbed better than those ingested directly from corn.
In age-related macular degeneration, a progressive eye disease that is the leading cause of blindness in older adults, the eyes are low in lutein and zeaxanthin. Doctors routinely recommend eating leafy greens, the only other vegetables rich in these antioxidants.
