Who is likely to be deficient of Lutein?
While a deficiency has not been identified, people who eat more lutein-containing foods appear to be at lower risk of macular degeneration. One study found that adults with the highest dietary intake of lutein had a 57% decreased risk of macular degeneration compared with those people with the lowest intake, and of the carotenoids, lutein and zeaxanthin are most strongly associated with this protection.1 In a preliminary study, a similar link was suggested between low dietary lutein and increased risk of cataracts.
