Lutein, a nutrient found in green vegetables, is thought to protect against common eye conditions such as cataracts and age-related macular degeneration, both of which cause blurred vision. Recently, researchers at Tufts University found that an even better, more absorbable source of lutein can be found in eggs.
After comparing the amounts of lutein absorbed from spinach, two types of lutein supplements and lutein-enriched eggs, the researchers concluded that the eggs were superior in terms of lutein absorption. Reporting in the November 2004 issue of the Tuft’s University Health & Nutrition Letter, the researchers said, “The enriched egg increased the level of lutein in the subjects on average two times greater than spinach and three times greater than lutein supplements. . . . It might be that enriched eggs are an ideal way to increase lutein consumption.”
