Benefits of Green Tea- An Ultimate Guide to Unveil the Nature’s Love

Green tea is considered one of the best beverages in the world due to its health benefits. Initially, it was used as a medicine in India and China. Now it is being used in America, Europe and all across the world due to its miraculous health benefits. In the world, 2.5 million tons of tea leaves are produced annually, and 20% of it is green tea.

A lot of people get confused about the source of green tea and black tea. The fact is that the same plant Camellia sinensis produce both of these drinks. These differ in post-production processing. For green tea production, camellia leaves are readily steamed. Steam inhibits fermentation and denatures enzymes responsible for the breakdown of color pigment. In contrast, fermented leaves result in the production of oolong tea and black tea.

Green tea leaves mainly contain protein, amino acid, carbohydrates, fiber, polyphenol, caffeine and pigments. Healthy bioactive component polyphenol accounts for 30% of dry weight and caffeine 0.4-10% dry weight.
