12 Ways to Better Health with Green Tea For
centuries green tea has been credited with restorative and healing properties.
Recent scientific studies have confirmed the truth of these claims. Green
tea is loaded with polyphenols - naturally occurring chemical compounds packed
with antioxidant power. These polyphenols give tea its unique flavor and color.
Despite the fact that green, black and oolong tea
are derived from the same plant, Camellia sinensis/Camellia assamica, the different
preparation processes used to produce each tea result in variations in the content
of active ingredients. By weight, polyphenols comprise
30 percent of the green tea leaf. Although it can vary, one cup of green tea typically
contains 252 mg of four separate polyphenols. The antioxidant potential of green
tea polyphenols has amazed even the scientists studying green tea. One study compared
green tea extract with the 'gold standard' of antioxidants: vitamin E. The extract
was shown to pack two hundred times the antioxidant punch of vitamin E.(1)

Anioxidants
have been shown to boost immunity, promote longevity, guard against heart disease
and cancer, and produce positive effects on cholesterol. Scientific
research confirms that green tea reduces the incidence of dental cavities, although
researchers believe that the polyphenols are primarily responsible for the anti-cavity
effects.(2) Green tea
supports good health in a dozen diverse ways. The following summary shows that
almost every system of the body is beneficially affected by green tea: (3) |
 |
* Lowers total cholesterol & LDL ('bad') cholesterol levels * Increases
HDL ('good') cholesterol levels * Reduces blood pressure & acts as a 'blood
thinner' thus decreasing risk of stroke * Reduces risk of & likelihood
of death from heart attack by supporting good circulatory and cholesterol health
* Aids in the proper function of the liver thus helping to detoxify the body
* Promotes normal blood sugar and insulin regulation thus aiding the control
of diabetic conditions * Reduces the risk of cancer by preventing it from
starting and spreading * Boosts longevity * Enhances immune function and
aids in fighting bacterial infections * Aids digestion and prevents ulcers
of stomach, esophagus and small intestine (4) *
Prevents dental cavities and gingivitis * Promotes weight loss by reducing
the rate and amount of dietary carbohydrates absorbed by the body (5)

| So
how many cups of green tea does one need to drink to obtain these wonderful health
benefits? The average green tea intake in Asian countries is about three cups
daily, or 240 to 320 milligrams of polyphenols. Scientific studies indicate that
300 to 400 mg of polyphenols, taken in the form of green tea extract, are needed
for effective health protection. This dosage is equivalent to four to ten cups
of green tea daily. (6) For
a comprehensive look at how green tea performs its healthful magic, read The
Green Tea Book, China's Fountain of Youth (by Lester A. Mitscher, Ph.D and
Victoria Dolby. They explore the scientific research, discuss green tea's long
and rich history, and examine the individual benefits green tea offers. An informative
and easy read. |
