This figure presents the distribution of macular pigments constituent carotenoids meso-zeaxanthin, zeaxanthin and lutein on a healthy human retina.
33.
Additionally, due to the abundance of lutein and vitamin A in carrots, they are often recommended to maintain good eyesight.
34.
For example, the Lcy-e gene is highly expressed in leaves, which results in the production of the carotenoid lutein.
35.
Lutein is not used as a colorant in other foods due to its limited stability, especially in the presence of other dyes.
36.
There is plasma concentrations of lutein and zeaxanthin, and an increased risk of developing age-related macular degeneration ( AMD ).

38.

39.
Other carotenoid phytochemicals, such as lycopene, lutein and zeaxanthin, are not yet fully understood for their possible nutritional or biological effects.
40.
The study reported that there was no overall additional benefit from adding omega-3 fatty acids or lutein and zeaxanthin to the formulation.
