The
SECRET that
chocolate companies don't want you to know!

Biosynthesis
Flavonoids are synthesized by the phenylpropanoid metabolic
pathway in which the amino acid phenylalanine is used to produce
4-coumaroyl-CoA[3]. This can be combined with malonyl-CoA to yield
the true backbone of flavonoids, a group of compounds called
chalcones, which contain two phenyl rings (see polyphenols).
Conjugate ring-closure of chalcones results in the familiar form of
flavonoids, the three-ringed structure of a flavone. The metabolic
pathway continues through a series of enzymatic modifications to
yield flavanones → dihydroflavonols → anthocyanins. Along this
pathway, many products can be formed, including the flavonols,
flavan-3-ols, proanthocyanidins (tannins) and a host of other
polyphenolics.
Good sources of flavonoids include all citrus fruits, berries,
ginkgo biloba, onions parsley, pulses, tea (especially white and
green tea), red wine, seabuckthorn, and
dark chocolate
(with a cocoa content of seventy percent or greater).

Dark chocolate

Flavanoids exist naturally in cacao, but because they can be bitter,
they are often removed from chocolate, even the dark variety.
Active
Biological Effects
Flavonoids are widely distributed
in plants fulfilling many functions including producing yellow or
red/blue pigmentation in flowers and protection from attack by
microbes and insects. The widespread distribution of flavonoids,
their variety and their relatively low toxicity compared to other
active plant compounds (for instance alkaloids) mean that many
animals, including humans, ingest significant quantities in their
diet. Flavonoids have been referred to as "nature's biological
response modifiers" because of strong experimental evidence of their
inherent ability to modify the body's reaction to allergens,
viruses, and carcinogens. They show anti-allergic, anti-inflammatory, anti-microbial and anti-cancer
activity.
Consumers and food manufacturers have become interested in
flavonoids for their medicinal properties, especially their
potential role in the prevention of cancers and cardiovascular
disease. The beneficial effects of fruit, vegetables, and tea or
even red wine have been attributed to flavonoid compounds rather
than to known nutrients and vitamins
Active Health benefits aside from
antioxidant values
In 2007, research conducted at the
Linus Pauling Institute and published in Free Radical Biology
and Medicine indicates that inside the human body, flavonoids
themselves are of little or no direct antioxidant value. Unlike in
the controlled conditions of a test tube, flavonoids are poorly
absorbed by the human body (less than 5%), and most of what is
absorbed is quickly metabolized and excreted from the body.
The huge increase in antioxidant capacity of blood seen after the
consumption of flavonoid-rich foods is not caused directly by the
flavonoids themselves, but most likely is due to increased uric acid
levels that result from expelling flavonoids from the body.
According to Frei, "we can now follow the activity of flavonoids in
the body, and one thing that is clear is that the body sees them as
foreign compounds and is trying to get rid of them. But this process
of gearing up to get rid of unwanted compounds is inducing so-called
Phase II enzymes that also help eliminate mutagens and carcinogens,
and therefore may be of value in cancer prevention... Flavonoids
could also induce mechanisms that help kill cancer cells and inhibit
tumor invasion."
Cocoa Inhibits Diarrhea
A study done at Children's Hospital & Research Center Oakland, in
collaboration with scientists at Heinrich Heine University in
Germany, has shown that epicatechin, quercetin and luteolin
can
inhibit the development of fluids that result in diarrhea
by targeting the intestinal cystic fibrosis transmembrane
conductance regulator Cl– transport inhibiting cAMP-stimulated Cl–
secretion in the intestine.
Active
Important flavonoids
Active
Quercetin
Quercetin is a flavonoid and, to be more specific, a 'flavonol',
that constitutes the aglycone of the glycosides rutin and
quercitrin. In studies, quercetin is found to be the most active of
the flavonoids, and many medicinal plants owe much of their activity
to their high quercetin content. Quercetin has demonstrated
significant anti-inflammatory activity because of direct inhibition
of several initial processes of inflammation. For example, quercetin
inhibits both the production and release of histamine and other
allergic/inflammatory mediators. In addition, it exerts potent
antioxidant activity and vitamin C-sparing action. It may also help
to prevent some types of cancer.
Active
Epicatechin
Epicatechin (EC)
Epicatechin improves blood flow and thus seems good for cardiac
health. Cocoa, the major ingredient of dark chocolate, contains
relatively high amounts of epicatechin and has been found to have
nearly twice the antioxidant content of red wine and up to three
times that of green tea in in-vitro tests. But in the test outlined
above it now appears the beneficial antioxidant effects are minimal
as the antioxidants are rapidly excreted from the body.
Active
Oligomeric Proanthocyanidins
Proanthocyanidins extracts demonstrate a wide range of
pharmacological activity. Their effects include increasing
intracellular vitamin C levels, decreasing capillary permeability
and fragility, scavenging oxidants and free radicals, and inhibiting
destruction of collagen, the most abundant protein in the body.

Active
Citrus

The citrus bioflavonoids include hesperidin (a glycoside of the
flavanone hesperetin), quercitrin, rutin (two glycosides of the
flavonol quercetin), and the flavone tangeritin. In addition to
possessing antioxidant activity and an ability to increase
intracellular levels of vitamin C, rutin and hesperidin exert
beneficial effects on capillary permeability and blood flow. They
also exhibit some of the anti-allergy and anti-inflammatory benefits
of quercetin. Quercetin can also inhibit reverse transcriptase, part
of the replication process of retroviruses. The therapeutical
relevance of this inhibition has not been established.
Hydroxyethylrutosides (HER) have been used in the treatment of
capillary permeability, easy bruising, hemorrhoids, and varicose
veins.
Active
Ginkgo
Leaf extract from the Ginkgo tree is widely marketed as an herbal
supplement. The active ingredients are flavoglycosides.
Active
Wine
Grape skins contain significant amounts of flavonoids as well as
other polyphenols. Both red and white wine contain flavonoids;
however, since red wine is produced by fermentation in the presence
of the grape skins, red wine has been observed to contain higher
levels of flavonoids, and other polyphenolics such as resveratrol.
