Carrot Juice, Daucus Carota
Carrots
are an excellent source of antioxidant compounds, and the richest vegetable
source of the pro-vitamin A carotenes. Carrots' antioxidant compounds
help protect against cardiovascular disease and cancer and also promote
good vision, especially night vision. Source of certain carotenoids
and immune boosting enzymes. Legendary for youthfulness, energy and
freedom from colds and flu. Antiparasitic.

Carrots contain
many important nutrients: beta carotene and other carotenoids, B
vitamins, vitamin C, the minerals calcium and potassium, and much more.
Of all of these, it is beta carotene that traditionally has received the
most attention.
Beta carotene
Beta carotene is one of about 500 similar compounds called
carotenoids, which are present in many fruits and vegetables. The body
changes beta carotene into vitamin A, which is important in
strengthening the immune system and promoting healthy cell growth.
However, beta carotene is much more than the precursor for vitamin A.
Only so much beta carotene can be changed into vitamin A, and that which
is not changed contributes to boosting the immune system and is also a
potent antioxidant. Antioxidants fight free radicals and help prevent
them from causing membrane damage, DNA mutation, and lipid (fat)
oxidation, all of which may lead to many of the diseases that we
consider "degenerative."
Alpha carotene
Beta carotene is not the only carotenoid. Often overlooked, and also
found in carrots, is alpha carotene. According to an article in NCI
Cancer Weekly (Nov. 13, 1989), Michiaki Murakoshi, who leads a team of
biochemists at Japan's Kyoto Prefectural University of Medicine,
contends that alpha carotene may be more powerful than beta carotene in
inhibiting processes that may lead to tumor growth. Murakoshi indicates
that neuroblastoma (cancer) cells coated with carotenoids experience a
drop in N-myc activity compared to untreated cells. N-myc is a gene that
codes for cell growth-stimulating proteins and can contribute to cancer
formation and growth. Alpha carotene was found to be about ten times
more inhibitory toward N-myc activity than beta carotene. Murakoshi
concludes that all types of carotenoids should be studied for possible
health benefits.
Carotenoids and Heart Disease
When six epidemiological studies that looked at the association of diets high
in carotenoids and heart disease were reviewed, the research demonstrated that
high-carotenoid diets are associated with a reduced risk of heart disease. In
one study that examined the diets of 1,300 elderly persons in Massachusetts,
those who had at least one serving of carrots and/or squash each day had a 60%
reduction in their risk of heart attacks compared to those who ate less than one
serving of these carotenoid-rich foods per day.
Better Vision
Beta-carotene helps to protect vision, especially night vision. After
beta-carotene is converted to vitamin A in the liver, it travels to the retina
where it is transformed into rhodopsin--a purple pigment that is necessary for
night-vision. Plus beta-carotene's powerful antioxidant actions help provide
protection against macular degeneration and the development of senile
cataracts--the leading cause of blindness in the elderly.
Carotenoids and Cancer
Carrots are by far one of the richest source of carotenoids--just one cup
provides 16,679 IUs of beta-carotene, more than 250% of the RDA, and 3,432 REs
(retinol equivalents), or roughly 686.3% the RDA for vitamin A. High carotenoid
intake has been linked with a 20% decrease in postmenopausal breast cancer and
an up to 50% decrease in the incidence of cancers of the bladder, cervix,
prostate, colon, larynx, and esophagus. Extensive human studies suggest that a
diet including as little as one carrot per day could conceivably cut the rate of
lung cancer in half. Remember the study in which heavy long-term cigarette
smokers were given synthetic beta-carotene, and it did not appear to prevent
them from developing lung cancer? Well, not only is synthetic beta-carotene not
biochemically identical to the real stuff found in carrots, but scientists now
think that carrots' protective effects are the result of a team effort among
several substances abundant in carrots, including alpha-carotene--another, less
publicized carotenoid. A recent National Cancer Institute study found lung
cancer occurence was higher in men whose diets did not supply a healthy intake
of alpha-carotene.
Carotenoids and Blood Sugar
Intake of foods such as carrots that are rich in carotenoids may be
beneficial to blood sugar regulation. Research has suggested that physiological
levels, as well as dietary intake, of carotenoids may be inversely associated
with insulin resistance and high blood sugar levels.
Protection against Emphysema
If you or someone you love is a smoker, or if you are frequently exposed to
second hand smoke, then making vitamin A-rich
foods, such as carrots, part of your healthy way of eating may save your life,
suggests research conducted at Kansas State University.
While studying the relationship between vitamin A, lung inflammation, and
emphysema, Richard Baybutt, associate professor of nutrition at Kansas State,
made a surprising discovery: a common carcinogen in cigarette smoke,
benzo(a)pyrene, induces vitamin A deficiency.
Baybutt's earlier research had shown that rats fed a vitamin A-deficient diet
developed emphysema. His latest animal studies indicate that not only does the
benzo(a)pyrene in cigarette smoke cause vitamin A deficiency, but that a diet
rich in vitamin A can help counter this effect, thus greatly reducing emphysema.
In his initial research, Baybutt took just weaned male rats and divided them
into two groups, one of which was exposed to cigarette smoke, and the other to
air. In the rats exposed to cigarette smoke, levels of vitamin A dropped
significantly in direct correlation with their development of emphysema. In the
second study, both groups of rats were exposed to cigarette smoke, but one group
was given a diet rich in vitamin A. Among those rats receiving the vitamin
A-rich foods, emphysema was effectively reduced.
Baybutt believes vitamin A's protective effects may help explain why some
smokers do not develop emphysema. "There are a lot of people who live to be 90
years old and are smokers," he said. "Why? Probably because of their diet? The
implications are that those who start smoking at an early age are more likely to
become vitamin A deficient and develop complications associated with cancer and
emphysema. And if they have a poor diet, forget it." If you or someone you love
smokes, or if your work necessitates exposure to second hand smoke, protect
yourself by making sure the World's Healthiest Foods rich in vitamin A (carrot's
beta-carotene is converted in the body into vitamin A) are a daily part of your
healthy way of eating. (October 21, 2004)
Description
Carrots benefits are legendary. Bet your mother told you that eating carrots
would keep your eyesight bright. While we usually associate carrots with the color
orange, in fact, carrots
grow in a host of other colors including white, yellow, red, or purple, the
latter being the color of the original variety. The carrot is a plant with a
thick, fleshy, deeply colored root, which grows underground, and feathery green
leaves that emerge above ground. It is known scientifically as Daucus carota,
a name that can be traced back to ancient Roman writings of the 3rd century.
Carrots belong to the Umbelliferae family, named after the umbrella
like flower clusters that plants in this family produce. As such, carrots are
related to parsnips, fennel, caraway, cumin and dill. There are over 100
different varieties that vary in size and color. Carrots can be as small as two
inches or as long as three feet, ranging in diameter from one-half of an inch to
over 2 inches. Carrot roots have a crunchy texture and a sweet and minty
aromatic taste, while the greens are fresh tasting and slightly bitter.
