Vision and Macular Health - from Source Naturals - Lutein
One of the more surprising discoveries of
modern nutritional science is that the very pigments
which give brilliant color to our fruits and
vegetables are powerful nutrients which can protect
us from the rigors of time and environment.
Lutein is one of the most recent discoveries in
this field. In our diets, it’s found most abundantly
in dark green leafy vegetables such as spinach,
collards and kale. Like beta-carotene, lutein is a
powerful antioxidant which studies show can
contribute to the protection of cells. But the most
promising application of lutein may be its
beneficial influence on the eyes, particularly in
regard to macular degeneration.
Source Naturals LUTEIN is a concentrated
source of this important natural nutrient.
Like the beta-carotene that makes carrots orange and the lycopene that makes tomatoes red,
lutein is a carotenoid. It is the pigment that makes corn yellow, and gives marigolds their brilliant
golden color. One of the most interesting aspects of the way carotenoids interact with the human
body – beyond their broad spectrum antioxidant activity – is their tendency to be “organ specific.”
Different carotenoids have an affinity for different organs in the body. In the case of lutein, it
is found concentrated in the structure of our eyes.
Vision and Macular Health
The process of vision involves light being
focused through the lens and onto the retina,
the paper-thin tissue lining the back of the eyeball.
The central portion of the retina, called
the macula, receives the most light. Its millions
of cells produce the sharp vision needed to read
and see objects clearly. With age, tiny blood
vessels grow over this area, causing a gradual
distortion and loss of vision.
This degeneration of the macular region of the
retina is the leading cause of irreversible visual
impairment in the USA today. It affects almost
20% of people past the age of 65. Research has
shown that these people have lower tha ...
