From China, green tea spread to Japan, Korea, and other parts of Asia, where it became an integral part of the culture and tradition.

The production process of green tea is crucial in determining its nutritional value. Green tea is made from the leaves of the Camellia sinensis plant, which is also used to produce black tea.

Factors Affecting Nutritional Value

- Quality of the leaves: High-quality leaves are rich in antioxidants and other nutrients.
