Benefits of Green tea
-
Cancer Prevention
The
majority of research to date on Green tea focuses on cancer prevention.
Population studies in Asia have found lower rates of cancer among those who
consume large amounts of Green tea. (10) A study of Japanese men
and women with a 13 year follow up revealed that increased consumption of
Green tea was associated with a delay of diagnosis of cancer. (1)
Mean age at cancer onset among men or women who consumed over 10 cups of
Green tea a day was 7.6 years later than those consuming less than three
cups. It was noted that the delay in cancer was only relevant to those below
the age of 79. Animal, human and test tube studies have shown that Green tea
may reduce the risk of prostate, breast, esophageal, lung, skin, pancreatic
and bladder cancers.(2)
Of the
hundreds of studies done on Green tea, only about 10% have involved humans.
(10) While the data is promising,
it is still limited. The good news
is that this data is providing insight and direction for further studies to
be done on the chemo preventive effects of Green tea.

Protecting the heart
There
is early evidence, though not conclusive, that regular intake of Green tea
may reduce the risk of cardiovascular diseases. Several well designed
studies have demonstrated significant risk reduction in people who drink
Green tea regularly.
>Coronary Heart Disease
A
recent cohort study assessed the effects of Green tea consumption on 8,522
Japanese men over a period over 12 years. The data showed that men who drank
10 cups of Green tea daily versus the men who consumed only three cups daily
had a lower risk of death from coronary heart disease. (3)
>Stroke
A
cohort study of Japanese women demonstrated an inverse relationship between
Green tea consumption and the incidence of stroke. The study followed 5,910
Japanese women who neither smoked nor drank alcohol for four years.
The
incidence of stroke was significantly lower in women who consumed at least
three to four cups of Green tea per day. (3)(11)
>Hypertension
In a
study published in the Archives of Internal Medicine, researchers concluded
that consumption of Green or oolong tea at 120 ml or more per day, for one
year, significantly reduced the risk of developing hypertension. (8)
Researchers also examined the impact of long term tea consumption on the
risk of developing hypertension in 1,507 men and women. Those who
consistently drank 120 ml or more of tea per day had a lower risk of
developing hypertension.
-
Exercise Endurance
People
have long used Green tea for energy. A new study might shed light on Green
tea as a tool for endurance. Published by the American Physiological
Society, the study demonstrated that Green tea extract markedly improved
endurance capacity in mice. (5)
Swimming time to exhaustion was evaluated in mice fed Green tea extract. The
mice that were fed Green tea extract had prolonged endurance capacity by
8-24% and the effect was accompanied by a stimulation of lipid metabolism.
It is also noted that the effects were dose dependent. Although not yet
confirmed in human studies, these results suggest Green tea might be a
useful tool for athletes.
-
Weight Loss
The
newest research on Green tea has been in the area of weight loss. Research
suggests Green tea promotes weight loss by favorably affecting lipid
metabolism in the blood, and through the stimulation of thermogenesis
(fat-burning).(4,12) Regarding Green tea and thermogenesis, a
study examining the benefits of functional foods for weight control showed
that Green tea increased energy expenditure over a 24 hour period. This is
probably due to the combination of catechins and caffeine naturally
occurring in Green tea.(4) Green tea extract looks to be a
promising new tool for weight loss.
Green tea: supplement vs. beverage
While
most of the studies on Green tea have been done on the consumption of brewed
tea, a study published in the American Journal of Clinical Nutrition
found that catechins absorption was enhanced when tea polyphenols were
administered as a Green tea supplement in pill form. (9) Simply
put, the Green tea in supplement form showed enhanced bioavailability
compared with that of Green or black tea in beverage form. Whether you
prefer to drink tea or take a pill, you are still getting the health
benefits of Green tea.
