Updated on February 22, 2013

Some health benefits of green tea are...

  • Green tea may have more health benefits than black tea because green tea is dried instead of fermented like black tea. The fermentation process destroys certain beneficial polyphenols.
  • CBS's The Early Show mentions ...

"Researchers in Japan conducted a study of 40,000 people ages 40-79. They followed people over 11 years and found that people who consume five or more cups of green tea a day, were 16 percent less likely to die from anything during that time compared to people who drink one cup a day."[4]

  • Some mice studies are finding that green tea catechins may be good for the brain by preventing oxidative damage of brain cells.[3]

The book The Chemistry of Calmsays ...

"Make pure water your main beverage. ... If you like green tea, you can drink it throughout the day." [page 69-70]

Unsweetened green tea can contain zero sugar. Its health benefit comes from its antioxidant capabilities. Green tea contains catechins such as epigallocatechin-3-gallate (EGCG) which inhibits cancer growth. Green tea is also good for the heart since it helps dilate blood vessels.
