Fruits and vegetables have ;yet another ;disease-fighting ;weapon to
offer you: Lutein. Studies show this carotenoid prevents and, to some
extent, ;reverses vision loss, immune system problems, cancer ;and
cardiovascular disease. With that in mind, load up your plate with
foods high in lutein -- ;carrots, corn, kale, spinach, Swiss chard,
collard, mustard greens, red peppers, dill, parsley, romaine lettuce,
tomatoes, potatoes and red, blue ;and purple fruits ;-- and read all
about what ;this amazing plant nutrient will do ;for your body.
Is your vision blurry? I ;know mine is after sitting in front of the
computer for a while. In that case, you and I need to eat ;more
lutein-rich foods, according to Drs. Michael R. and Marc ;R. Rose. In
their book, Save Your Sight, they write, "A few weeks after consuming
more lutein-rich foods or lutein supplements, some normal-sighted
people report less glare, improved color vision and sharper vision."
Theory suggests that lutein and its ;companion carotenoid zeaxanthin
may save our sight by acting "as a shield ;or filter that helps to
absorb harmful UVB light and dangerous free-radical molecules, both of
which threaten the retinal tissue," according ;to Life Extension
Foundation's Disease Prevention and Treatment.
Though everyone's sight could benefit from a diet high in lutein, it
can literally save the sight of those who have ;family histories of
macular degeneration and other vision loss problems. ;If someone in
your family has experienced loss of sight in old ;age, then your
high-lutein diet ;should start long ;before you reach middle ;age. In a
Harvard University-based study, women with diets high in lutein ;and
zeaxanthin experienced a 22 ;percent reduced risk of ;cataracts, while
men reduced their risk by 19 percent, according to ;Reader's Digest's
Fight Back with Food.
Based on a study described by Laurie Deutsch Mozian in her book, Foods
that ;Fight ;Disease, a dietary intake of only six milligrams of lutein
per day decreases your chances of developing ;age-related macular
degeneration by 43 percent. For that reason, in Bill Gottlieb's
Alternative Cures, Dr. Mark Grossman of the Integral Health Center in
Rye and New Paltz, New York, advises, "Everyone over the age of 50
should be taking lutein supplements." However, if you are already
experiencing macular degeneration or other vision problems, a
high-lutein diet can still help you save your ;sight ;by increasing the
density ;of your macular pigment. "Macular degeneration ;may be
stabilized or reversed with nutritional intervention," says ;Dr.
Grossman. ;He later goes on to say, ;"By far, it's (lutein) the number
one nutritional ;treatment for the ;disease."
Not only will lutein save your sight, it may also boost your immune
system and, ;accordingly, prevent cancer. ;"Healthy people seeking to
boost overall immune function should consider ;consuming 5,000 IU of
beta-carotene daily, along with other carotenoids, ;such as lycopene
and lutein," writes the Life Extension ;Foundation. By boosting your
immunity, lutein decreases your ;chances of getting cancer, since
development of cancer as a disease ;is associated with immune system
impairment. I know you've probably heard this a million times, but
just in case you haven't, I'll say it again: We all have cancer cells.
Cancer cells develop in our bodies all the time, but ;our immune
systems normally remove the malignant cells before they can develop
into the ;symptoms we ;call cancer. In addition to boosting your ;immune
system, lutein may ;also fight cancer ;by both protecting your ;cells
from free radical damage and increasing cell-to-cell communication,
thus preventing them from turning malignant.
However lutein prevents cancer, we know it works. According to
Professor Ralph Moss' book, Antioxidants against Cancer, more than 250
scientific papers demonstrate ;lutein's potential as an anti-cancer
agent. In a study described in ;Mark Stengler's Natural Physician's
Healing Therapies, people with high-lutein diets at any age decreased
their chances of developing ;colon ;cancer by 17 percent; furthermore,
young people with high-lutein diets decreased their chances by 34
percent. Studies show ;that a diet high in lutein will also ;decrease
your ;chances of other cancers, including cancers of the lung and
breast. ;According to a study reported ;in Disease Prevention and
Treatment, women who have low ;levels of lutein have a 2.08-fold
increased ;risk of breast cancer, so not eating enough lutein-rich
foods ;can actually harm ;you.
In this age of fast food and junk food, cardiovascular disease is more
prevalent than ever. Instead of ;eating french fries as our vegetables,
we should be eating more lutein-rich foods. The Life ;Extension
Foundation reports the results in one study, in which participants
with the highest blood levels of lutein showed virtually no arterial
wall thickening. "This was ;a good sign that the bad ;LDL cholesterol
had ;not oxidized inside them and formed ;the dangerous plaque that can
lead to heart attacks," the editors of FC&A Medical ;Publishing
conclude from the results of the ;same study. ;High-lutein diets can
even decrease smokers' odds of developing cardiovascular disease,
according ;to a study Selena Yeager describes in her book, New Foods
For Healing. In this study of 1,900 men, smokers with high lutein
levels in their blood experienced 25 percent fewer heart attacks than
those with low lutein levels.
It's easy to add more lutein to your diet because it's found in ;so
many foods. Just refer back to the list you read above. Moreover,
"lutein ;is five times more readily available from ;vegetables than
beta-carotene," writes Professor Moss. Just adding a few ;more fruits
and vegetables to your plate each day may save your sight, boost your
immune ;system, prevent you from developing cancer and reduce your
chances of having a heart attack. It's ;so easy to be so healthy.
The experts speak on lutein and its health benefits:
Other useful nutrients ;for ensuring vision health are the carotenoids
lutein, lycopene, and zeaxanthin. Food sources of ;lutein: kale,
collard and ;mustard greens, spinach, Swiss chard, red peppers,
parsley, romaine lettuce, dill, celery, carrots, corn, tomatoes,
potatoes, and red, blue, and purple ;fruits...
Alternative Medicine ;by Burton Goldberg, page 946
Even though cooking any food reduces the amount of ;lutein
will
absorb more of that protective substance if you add a little ;bit of
fat when cooking.
;use olive oil instead of animal fats.

Lutein ;and vision-health benefits
A few ;weeks ;after ;consuming more lutein-rich foods or lutein
supplements, some ;normal-sighted people report ;less glare, ;improved
color vision, and sharper vision.

A study conducted by researchers ;at Harvard University showed that
women with the highest intake of dietary lutein (and its companion
carotenoid, zeaxanthin) had ;a 22% reduced risk for cataracts, while
men reduced their risk by 19%.

The study showed that a daily intake of 6 milligrams of lutein ;was
associated with ;a 43-percent lower incidence of age-related macular
degeneration.
Foods That Fight Disease by Laurie Deutsch Mozian MS RD, ;page 122
"Everyone over the age of 50 should be taking lutein supplements," Dr.
Grossman says. That's because many scientific studies have shown that
regular intake of the nutrient, which is a pigment found in leafy
green vegetables such as kale, collard greens, and spinach, can
prevent macular degeneration, he says.
Alternative Cures by Bill Gottlieb, page 428
"Macular degeneration may be stabilized or reversed with nutritional
intervention," says Marc Grossman, O.D., an optometrist, licensed
acupuncturist, and codirector of the Integral Health Center in Rye and
New Paltz, New York. And the single ;most important nutrient to prevent
or ;treat ;it is lutein.
Alternative ;Cures ;by Bill Gottlieb, ;page 428
Besides preventing the condition, lutein may be ;able to stop or even
reverse existing macular degeneration by ;increasing the density of the
macula pigment. "By ;far, it's the number one nutritional treatment for
the disease," Dr. Grossman says.

zeaxanthin
Together, these two carotenoids help protect
various delicate tissues from free radical damage. lutein ;even beats
beta-carotene at protecting fats inside eye cells from such damage.
Antioxidants Against Cancer by Ralph Moss PhD, page 36
The fact that lutein and zeaxanthin are particularly concentrated in
these parts of the eye suggests ;that they may act as a shield or
filter that helps to absorb harmful UVB light and dangerous
free-radical molecules, both of ;which ;threaten the retinal tissue

Lutein and immune system function in general
Healthy people seeking to boost overall immune function should
consider consuming 5000 IU of ;beta-carotene daily, along with other
carotenoids, such as lycopene and lutein.

When plasma levels were measured for all antioxidant micronutrients
in persons with HIV and in controls, ;it was observed that these
patients showed a significant depletion of all ;carotenoids (lutein,
lycopene, ;alpha-carotene, etc.) and vitamin C.

Lutein ;as an anti-cancer ;agent
A ;family of nutrients called lutein and zeaxanthin
. They're
antioxidants, which means that they have the ability to ;neutralize
harmful free radicals. In this way, antioxidants (see related ;ebook ;on
antioxidants) safeguard the maculae against free-radical damage.

"Lutein and lycopene possess exceptionally high antioxidant capacity
compared to other carotenoids and may be useful in preventing cancer,"
said Dr. Fred Khachik, a chemist with the U.S. Department ;of
Agriculture. lutein promotes healthy immunity ;and decreases the ;growth
of cancer. There are already over 250 scientific ;papers referring to
lutein's potential as an anticancer agent. And lutein is five times
more readily available from vegetables than beta-carotene.

A recent study showed ;that high-lutein diets were associated with a 17
percent decrease in colon cancer risk, and ;young ;people with ;a diet
high in ;lutein had a 34 percent lower risk of colon cancer.

;Eating a lutein-rich diet cut ;colon ;cancer risk ;by 17%.
Theory:
lutein protects colon cells from ;damage caused by highly ;reactive
compounds called free radicals. Good sources of lutein include
tomatoes, carrots, oranges, broccoli, ;kale, ;Romaine lettuce and spinach.

At Japan's ;National Cancer Center Research Institute in Tokyo,
scientists showed that lutein protects against the formation of colon
cancer, as measured by the number of ;pre-cancers per mouse. (203,308)

The risk of ;breast cancer associated with low levels of other
carotenoids was similar, that is, a ;2.08-fold increased risk if lutein
is ;deficient
;Analysis showed that lycopene was associated with
decreased breast ;cancer risk ;in postmenopausal women, but in
premenopausal women, lutein offered greater protection (Hulten et al.
2001).
Disease Prevention And Treatment ;by Life Extension ;Foundation, page 220
Lutein has many beneficial effects in experimental animals. It
increases ;the time until the tumor appears, suppresses the growth of
breast tumors, ;and also enhances ;the growth of normal white blood
cells. (340) What was particularly ;exciting was that ;very low amounts
of lutein, comprising no more than two-thousands of the overall diet
by weight, "can efficiently decrease mammary [breast] tumor
development and growth in mice." ;(341)
Antioxidants Against Cancer by Ralph Moss PhD, page 36
Lutein and cardiovascular health
For ;example, individuals participating in the Toulouse study who had
higher blood levels ;of lutein also had a lower incidence of coronary
artery disease
Participants with the highest blood levels of lutein
showed virtually ;no artery wall thickening, while those with the
lowest lutein ;levels showed increased arterial thickness. In ;addition,
lutein reduces the oxidation of LDL cholesterol
Disease Prevention And Treatment by Life Extension Foundation, ;page 466
The study followed 480 middle-aged men and women for 18 months. During
that time, those who had the most lutein in their bloodstream had
almost no increase in the thickness of their carotid (neck) arteries.
This was a ;good sign that the bad LDL cholesterol had not oxidized
inside them and formed the dangerous plaque that can lead to ;heart
attacks. Results of ;two other parts of the study, one done in the lab
with human tissue and the ;other ;with mice, supported the findings of
the first.
The Folk Remedy Encyclopedia by the Editors of FC&A Medical
Publishing, page 184
In a study of almost ;1,900 ;men, Dr. Morris and his colleagues found
that men who had the most carotenoids in their bloodnot just
beta-carotene but also such things as lutein and zeaxanthinhad 72
percent fewer heart attacks ;than those with the lowest levels. Even
smokers,
who got the most of these protective compounds had 25
percent fewer heart attacks than those who got the ;least.
New Foods For Healing by Selene Yeager, page 517
Dr. ;James ;Dwyer, who led this research, ;recommends eating plenty of
lutein-rich foods to keep your arteries clear. "A diet rich in
vegetables, including the dark green leafy variety," he says, "will
provide sufficient lutein ;to achieve the levels of persons in our study."
The Folk ;Remedy Encyclopedia by the Editors of FC&A Medical
Publishing, ;page 184
Lutein may also offer protection against lung infections and
osteoarthritis
Thirdly, certain plant alcohols in the leaves (notably xanthophyll
or lutein) ;disinfect the lungs, making it much ;harder for the bacilli
to remain there.
Heinerman's ;Encyclopedia of Healing Juices by John Heinerman, page 117
Other antioxidants beta cryptoxanthine, lutein, and lycopene
appeared to ;lower ;the chances ;of getting OA of the knee by 30 to 40
percent, Jordan says. These phytochemicals, which are common ;in orange
and green vegetables and tomatoes, put you ahead of the game when it
comes to arthritis protection.
