Green tea is an important nutrient that is either taken in the form of supplement or simply as a refreshing beverage. Green tea has many benefits for our health.
The first reference to green tea was found in Chinese literature dates back 5000 years ago. An emperor was sitting under a tree, reading with a cup of hot water. Some leaves fell into the water and the emperor drank it accidentally. He liked the taste of the drink and felt much re-vitalized. Green tea has been enjoyed in the Asian culture ever since. An ancient Chinese proverb said “Better be deprived of food for three days than eat for one”
The main ingredient in green tea is the Epigallocatechin (EGCG), carotenoids, tocopherols, ascorbic acids, chromium, manganese, selenium and zinc. Green tea leaves are steamed as opposed to black and white tea leaves, which are fermented. The steaming process prevent the EGCG is being oxidized, hence preserving the high level.

One cup of green tea contains 50-150 mg of polyphenols. Drink 2-3 cups a day will give you sufficient amount of antioxidants in your body.
