Many Health Benefits of Green Tea

As you may know, the benefits of green tea may include:
Lowers total cholesterol and LDL (bad)-cholesterol levels
Increases HDL (good)-cholesterol levels
Reduces blood pressure
Lowers blood sugar
Acts as "blood thinner"
Reduces the risk of cancer
Reduces the risk of heart attack
Decreases the risk of stroke
Decrease the risk of developing rheumatoid arthritis
Protects against Parkinson's disease
Enhances immune function
Acts as an antibacterial and antiviral agent
Helps burn extra calories
Prevents dental cavities and gum disease
Builds stronger bones
Boosts longevity
Green Tea - Increase Metabolism Naturally
A University of Geneva medical study showed that over a 24-hour period, green tea extract increases the metabolic rate by 4%. This increase in fat oxidation was higher than in subjects who used a placebo or caffeine. In addition, this stimulation of thermogenesis and fat oxidation by the green tea extract was not accompanied by an increase in heart rate. Thus, green tea extract has a distinct advantage over stimulant diet drugs, which can have adverse cardiovascular effects, especially for obese individuals with hypertension and other cardiovascular complications. The Green Tea 300 Weight Loss System provides a safe way to burn fat for healthy weight loss.
Green Tea - Suppress Appetite Safely
Scientists at the University of Chicago have found that green tea caused rats to lose up to 21 percent of their body weight. Rats injected with a green tea extract lost their appetites and consumed up to 60 percent less food after seven days of daily injections. The lead scientist on the study explained that a person would have to drink green tea almost constantly to obtain these results. Thus, the Green Tea 300 Weight Loss System was designed to provide the constant supply of high potency green tea needed to achieve these weight loss results.
Green Tea and Polyphenols
Unfortunately, polyphenols have a quick life span (short half life) of about 3 hours, thus the scientific reason behind researchers' recommendation to drink green tea a minimum of 8 times a day. This super antioxidant eliminates free radicals, the unstable molecules in the body that are the major cause of both aging and disease, which are continually attacking the body. EGCG, the most abundant and powerful of green tea's 5 main catechins, is dubbed the 'super antioxidant' because it is 200 times more powerful than the popular antioxidant vitamin E.

Just one example is a subgroup of polyphenols, exclusive to green tea, called catechins. These extremely high levels of polyphenols deliver green tea's unique results in several ways. Green Tea is the #1 source of polyphenols, chemical compounds found in fruits and vegetables.
So try green tea today to take advantage of what many people have already discovered and live a happier healthier life.

The Health Benefits of Green Tea - Fact or Fairytale?

The Case For Green Tea
Here are some examples. The Chinese have been using it for thousands of years to treat everything from headaches to depression and some of those claims are now starting to be verified by scientific research. Green tea devotees claim that is has many health benefits.
In addition, researchers at the University of Purdue concluded that a compound in green tea inhibits the growth of cancer cells. Cancer: The Journal of the National Cancer Institute published the results of a study in 1994 which indicated that drinking green tea reduced the risk of oesophageal cancer in Chinese men and women by nearly sixty percent. 1.
It improves the ratio of HDL cholesterol (that's the good kind) to LDL cholesterol (the bad kind). Cholesterol: Some research indicates that drinking green tea can lower your overall cholesterol levels. 2.
In other words the green tea accentuated the stimulant properties of caffeine which raise the metabolic rate. University researchers found that men who were given a combination of caffeine and green tea extract burned more calories than those given only caffeine or a placebo. Weight Loss: The American Journal of Clinical Nutrition published the results in 1999 of a study conducted at the University of Geneva in Switzerland.

3.
Tooth Decay: Green tea kills the bacteria that causes dental plaque, thus helping to prevent tooth decay. 4.
Skin preparations containing green tea - from deodorants to creams - are starting to appear on the market. Infection: Green tea's anti-bacterial properties mean that it can also be used to fight infections and to prevent food poisoning. 5.
What Is Green Tea's Magic Ingredient?
EGCG has also been shown to be effective in lowering LDL cholesterol levels, and inhibiting the abnormal formation of blood clots that are the leading cause of heart attacks and strokes. EGCG is a powerful anti-oxidant that can inhibit, or even stop, the growth of cancer cells without harming normal healthy tissue. The benefits you can get from green tea arise because it is rich in beneficial antioxidants, in particular EGCG (epigallocatechin gallate).
EGCG is twice as powerful as another beneficial antioxidant called resveratrol. This antioxidant occurs in red wine and is the main reason why the French have a lower incidence of heart disease than Americans, even though they have a diet rich in fats, dairy produce and red meat.
The fermentation means the EGCG is converted into other compounds that are not as beneficial. The other part of the secret behind green tea is that the leaves of the same Camellia sinensis plant but the leaves are fermented during processing.
The Case Against Green Tea
On the other hand, the US Food and Drug Administration issued a report in May 2006 stating there is no credible scientific evidence that drinking green tea reduces the risk of heart disease.
The FDA report said it reviewed 105 articles and other publications submitted as part of the petition, but it could not find any evidence to support claims of the beverage's health benefits.
Are There Any Harmful Side Effects?
As you could reasonably expect, if you drink too much green tea you may suffer from insomnia and to date, insomnia is the only negative side effect reported from drinking green tea. Green tea does contain caffeine, however it contains less than coffee - approx one third to just over half the amount for the same weight.
Better put the kettle on! So it seems you have nothing to lose and everything to gain by drinking it. Green tea can certainly do you no harm, except to keep you awake at night if you drink too much, whether because of the caffeine or the frequent trips to the bathroom. Research is now steadily accumulating scientific evidence that proves these benefits.

Green tea has been recognized for its curative properties for thousands of years.
