Antioxidant - Green Tea Information

Camellia Sinensis, the tea plant

Benefit: Longer lifespan

Literally hundreds of studies have been carried out documenting the health benefits of catechins, the group of antioxidants concentrated in the leaves of tea plants. Among the most startling studies was one published by the American Medical Association in 2006. The study followed more than 40,000 Japanese adults for a decade, and at the 7-year follow-up, those who had been drinking five or more cups of tea per day were 26 percent less likely to die of any cause compared with those who averaged less than a cup. Looking for more-immediate results? Another Japanese study broke participants into two groups, only one of which was put on a catechin-rich green-tea diet. At the end of 12 weeks, the green-tea group had achieved significantly smaller body weights and waistlines than those in the control group. Why? Because researchers believe that catechins are effective at boosting metabolism.

What makes green tea so special?

The secret of green tea lies in the fact it is rich in catechin polyphenols, particularly epigallocatechin gallate (EGCG). EGCG is a powerful anti-oxidant: besides inhibiting the growth of cancer cells, it kills cancer cells without harming healthy tissue. It has also been effective in lowering LDL cholesterol levels, and inhibiting the abnormal formation of blood clots. The latter takes on added importance when you consider that thrombosis (the formation of abnormal blood clots) is the leading cause of heart attacks and stroke.

Links are being made between the effects of drinking green tea and the "French Paradox." For years, researchers were puzzled by the fact that, despite consuming a diet rich in fat, the French have a lower incidence of heart disease than Americans. The answer was found to lie in red wine, which contains resveratrol, a polyphenol that limits the negative effects of smoking and a fatty diet. In a 1997 study, researchers from the University of Kansas determined that EGCG is twice as powerful as resveratrol, which may explain why the rate of heart disease among Japanese men is quite low, even though approximately seventy-five percent are smokers.

The healthiest beverage on the market.
Matcha contains nearly 10 times the polyphenols and antioxidants of regular teas.
Approximately 9 times the beta-carotene of carrots.
Significantly increases energy (over 8 to 10 hours) without the caffeine "jitters". 100% pure green tea.

Why don't other Chinese teas have similar health-giving properties? Green, oolong, and black teas all come from the leaves of the Camellia sinensis plant. What sets green tea apart is the way it is processed. Green tea leaves are steamed, which prevents the EGCG compound from being oxidized. By contrast, black and oolong tea leaves are made from fermented leaves, which results in the EGCG being converted into other compounds that are not nearly as effective in preventing and fighting various diseases.

Other Benefits

New evidence is emerging that green tea can even help dieters. In November, 1999, the American Journal of Clinical Nutrition published the results of a study at the University of Geneva in Switzerland. 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.

Green tea can even help prevent tooth decay! Just as its bacteria-destroying abilities can help prevent food poisoning, it can also kill the bacteria that causes dental plaque. Meanwhile, skin preparations containing green tea - from deodorants to creams - are starting to appear on the market.

Harmful Effects?

To date, the only negative side effect reported from drinking green tea is insomnia due to the fact that it contains caffeine.
