| Question: |
| What is Lutein? |
| Answer: |
|
Lutein belongs to a class of antioxidant compounds called carotenoids. Lutein is the
primary carotenoid found in the central area of the retina (known as the macula).
Consequently, lutein appears to be associated with protection from age-related
macular degeneration, a leading cause of blindness in older adults.
While the roles lutein and zeaxanthin play in the physiology of the eye are not completely known, the links between
lutein and eye health are so strong that several national and regional health
organizations have recommended an increase in dietary lutein. Lutein is believed
to function in two ways: first as a filter of high-energy blue and ultraviolet
light, and second as an antioxidant that quenches light-induced free radicals
and reactive oxygen species.
Lutein and zeaxanthin are found together in many food sources. Dark green leafy vegetables are the
primary source, but they are also present in lesser amounts in other colorful
fruits and vegetables, including broccoli, orange peppers, corn, peas, persimmons,
and tangerines.
Unfortunately, diet surveys indicate that few people consume enough of the foods
rich in lutein and zeaxanthin.
