Topic 2: Tea’s Nutritional Value
Brief Commentary
The common tea plant, Camellia Sinensis, produces a beverage called tea by steeping its leaves, twigs, or buds in hot water for 1 to 5 minutes.
Tea’s color is determined by its fermentation. White tea has the least fermentation. Black tea has the most fermentation. The fermentation process stops once the tea leaves have been fully dried. This is how the tea leaves retain their color (white, green, black) after drying.
Many people are aware today that tea has many health benefits (especially green tea). It is true that green tea was hardly available in grocery stores, convenience stores, and restaurants two years ago. Today, you can find it everywhere. Fast food restaurants serve it as well.
