Lutein
How to Use It
People showing protection from macular degeneration have been reported to have eaten about 6 mg of lutein per day from food. Lutein, in supplemental form, should be taken with fat-containing food to improve absorption.1
Where to Find It
Spinach, kale, collard greens, romaine lettuce, leeks, peas, and egg yolks are good sources of lutein.2
Possible Deficiencies
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.3 In a preliminary study, a similar link was suggested between low dietary lutein and increased risk of cataracts.4
