Boston -- Tufts scientists have discovered that eggs and leafy greens may protect against a common form of blindness. New research by University researchers appears to link components in the two foods to the prevention of macular degeneration -- a condition that causes blindness in 13 million Americans. "One in six Americans between the ages of 55 and 65 has some signs of macular degeneration," Tufts researcher Dr. Jim Joseph told WCVB-TV, ABC's Boston affiliate. "The good news is we're learning that dietary factors can help prevent this condition."
"Most healthy people can eat an egg a day and get lots of lutein and zeaxanthine in the process without any adverse risk for heart disease," Blumberg told WCVB.

said lutein and zeaxanthine -- two components found in eggs and
leafy vegetables, including spinach and kale -- act as antioxidants
and protect eyes from harmful ultraviolet eyes. According to Blumberg,
the dietary recommendations for fruits and vegetables -- at least
five servings each day -- and a couple eggs each week, should
be sufficient to protect the eyes.
