Here are 5 Benefits Green Tea Supported by Science

You can say green tea is the original tea, as it was drank this way by ancient people. It is the fresh leaves of the camellia sinensis plant, newly picked and very green. Prone to easy spoilage, and a bitter taste. Unlike black tea and other kinds of tea which are fermented or semi-fermented, green tea undergoes minimal processing. This is why it has the most potent amount of antioxidants and other health-boosting qualities.

Green tea is sometimes called Matcha or Matcha green tea powder. Matcha tea is a Japanese version of green tea, traditionally ground into a powder with a heavy stone. Green tea can also come in the form of whole leaves or rolled leaves, not just powder. You might expect to buy instant matcha tea, already mixed with creamer and sugar. Matcha is sold premixed because pure matcha tea has a sharp, grassy and bitter taste, which most people do not enjoy.

There are four different kinds of teas, which only differ in how the tea leaf is oxidized. There is white tea, which are white buds of the tea plant, nonoxidized, sold as soon as they are harvested. Green tea is also nonoxidized. The green tea leaves are only steamed, dried, pan-fried or roasted, then packed and ready to sell.

Green tea is not the most popular tea, people prefer black tea. Only 20% of tea drinkers worldwide will have green tea on the table, and most of those green tea drinkers are in Asia.  Oolong tea is fermented up to 80%. Black tea, the star of the tea world, is fully fermented or fully oxidized.

The fermentation process oxidizes polyphenols or antioxidant compounds. Tea polyphenols are responsible for many health benefits attributed to tea, including antioxidative, anti-inflammatory, and anticarcinogenic effects. The American Food and Drug Administration has been petitioned to include several health benefits of green tea on labels, which the FDA rejected in 2006. However, so much has happened since 2006, and there is now so much more information on the real benefits of green tea.
