Green Tea - Discover the Benefits Of This Super Antioxidant

"If we do not find time to take care of our health, we will
reluctantly have to find time for our illness"
-Hippocrates
Lately there's a lot of buzz in the news and online about
green tea and its' health benefits, particularly the role of
polyphenols in green tea.
Polyphenols are chemical compounds found in fruits,
vegetables and green tea and further divided into sub groups
called catechins. There are 4 major catechins in green tea
of which EGCG ((-)-epigallocatechin gallate (EGCG) is the
most potent and found in abundance in green tea.
This compound is dubbed the "super antioxidant" because it's
more powerful than the popular antioxidants Vitamin E &
Vitamin C. This super antioxidant eliminates free radicals,
the unstable molecules in the body that are the major cause
of both aging and disease, which continually attack the body
and leave the body vulnerable to disease.
All of which are vital for normal cellular function. They are highly reactive molecules; their activities cause damage to critical structures such as DNA, lipids and proteins. Free radicals indiscriminately kill cells, destroy enzymes and produce toxic chemicals which cause damage to cellular functions. Free radicals disrupt the biochemical processes within cells, and our body's natural defenses become compromised leading to illness.
Free radicals in the body are toxic forms of reactive oxygen
metabolites (ROM). It's ironic that on one hand oxygen
sustains us and on the other hand oxygen can be responsible
for much of the destruction and aging of our cells. Free
radicals are responsible for many ailments including but not
limited to aging, cancer, heart disease, stroke and
arthritis. Without an antioxidant line of defense, your
cells oxidize or breakdown faster thus speeding up the aging
process, it's the free radicals oxidative damage that makes
us age.
Since EGCG contained in green tea is a potent antioxidant it neutralizes free radicals and hence is responsible for the health promoting benefits listed below.
Lower total cholesterol and LDL (bad)-cholesterol levels
Increase HDL (good)-cholesterol levels
Reduce the risk of cancer
Reduce the risk of heart attack
Decrease the risk of stroke
Decrease the risk of developing rheumatoid arthritis
Enhance immune function
Act as an antibacterial and antiviral agent
Help in weight loss
Boost longevity due to potent antioxidant properties
As mentioned above EGCG is believed to possess 100 times more potency as an antioxidant than vitamin C and at least 25 times more potency as an antioxidant than vitamin C and at least 25 times more potency as an antioxidant than vitamin C and at least 25 times more potency than Vitamin E and protects cells and DNA from damage believed to be linked to cancer, heart disease and other potentially fatal illnesses. One cup of green tea usually provides 100-300 mg of polyphenols and contains EGCG in high concentrations.
We're just now scratching the surface of what green tea has to offer, new studies come out constantly that provide data on the effectiveness of green tea can be attributed to polyphenols, particularly EGCG. Green tea has been used for centuries in China for the health benefits it provides.
Green tea comes in various dosage forms but the more popular
versions are the liquid forms and the patch. The patch seems
to be gaining in popularity due to the convenience factor
and delivery of the same amount of the active ingredient of
green tea at a constant rate. Place the patch on the skin
and wear it for 48 hours and replace it every other day. It
can't get any simpler than that :-)
As you can see EGCG is an important component of green tea
responsible for all of the health benefits listed above.
Recent studies also indicate green tea as being effective in
promoting weight loss.
Green tea is truly a 'wonder compound' with a large array
of benefits for improving
health. It's been around for thousands of years and now it
has finally been re-discovered
for our benefit.

The Green Tea Secret

The chemical compound known as a phenol is characterized by an aromatic benzene ring with a hydroxyl group (OH) attached. This makes sense that poly-phenols refer to a chemical substance with more than one phenol group. Phenols function as potent antioxidants, reacting with free radicals. Phenols are responsible for the bright coloring in many fruits and vegetables. These fruit and vegetable phenols protect the plants from damage by disease and ultraviolet light.
Polyphenols are phytonutrients or phytochemicals. Phytonutrients are biologically active compounds in food. However, these phytonutrients are not classified as essential nutrients. This is because the body does not depend on these nutrients for proper bodily function. Phytonutrients do play a vital role in affecting our health just as significantly as vitamins and minerals do.
Polyphenols also protect and regenerate other dietary oxidants such as vitamin E. Polyphenols are potent free radical scavengers in the body. This is beneficial because excess levels of these cations promotes the generation of free radicals.

This reduces the absorption of the mineral. Polyphenols can form complexes with metal cations such as iron, zinc, and copper. Polyphenols are classified as flavonoids, which is a class of phytonutrient.
Polyphenols are plentiful in green tea. Polyphenols have been found to be more powerful as an antioxidant than even vitamins C and E. In particular, EGCG or epigallocatechin gallate is the major polyphenolic constituent of green tea. EGCG is a potent antioxidant. A number of chronic diseases have been thought to be caused by free radical damage such as cancer, aging, and heart disease.
Antioxidants protect the body from free radical damage. What are free radicals? Free radicals are caused by cigarette smoking, radiation, pollution, and herbicides. Free radicals are atoms with unpaired electrons in the outer shell. The unpaired electrons make free radicals unstable. Free radicals want only to be stable. Free radical stability requires the electrons to be paired. Free radicals are extremely reactive and will oxidize the nearest molecule.
In fact, researchers believe this is how many forms of cancer arise. DNA and free radical interactions usually result in mutations that adversely affect the cell cycle and potentially lead to malignancy. However, DNA is usually preferred. Free radicals can attack proteins, carbohydrates, lipids, and DNA.

This creates a chain reaction continuing until the disruption of a living cell. Oxidizing causes the free radical to gain an electron but also creates another free radical.
The antioxidant is stable with or without the electron, making this a win-win situation. Antioxidants donate an electron to the free radical, hence stabilizing the free radical and preventing damage. Antioxidants safely interact with free radicals to prevent damage to vital molecules.

Antioxidants protect the body from damaging oxidation reactions.
Black teas and some green teas are fermented and roasted, damaging the bioactive substances in the tea leaf. Steamed white and green tea retains more polyphenols and nutrients than roasting and fermenting. Of course, the level of polyphenols along with other nutrients is based on how the tea is processed. Polyphenols can be found in white, black, and green tea.
Green tea studies suggest an increase in exercise endurance by improving the metabolism of fat. Green tea has been shown to protect the brain from oxidative stress and lower monoamine oxidase activity; preventing age related brain degeneration. Green tea helps prevent cavities, strengthens teeth, and is thought to kill oral bacteria that is responsible for bad breath.

Regular consumption of green tea shows no significant side effects. Dietary intake of green tea has been linked to a reduced risk of cancer and heart disease. Many studies have been done on the health benefits of green tea. Why should you drink green tea?
Green tea offers many health benefits to those who drink green tea regularly. Besides offering antioxidant benefits, green tea is excellent as a weight loss supplement offering weight loss results and safety. Of course, green tea should be used in combination with a healthy diet and exercise program. If you take medications for a health condition, consult your doctor before adding green tea to your diet.
