Tea is a widely consumed beverage enjoyed by people of all ages. Its popularity stems from its rich flavor, cultural significance, and potential health benefits. This article delves into the composition of tea, its effects on the body, and considerations for its consumption.
Composition of Tea
Tea is derived from the leaves of the Camellia sinensis plant. The different types of tea, such as green tea, black tea, and herbal tea, arise from the processing methods and the plant’s origin.
Green tea undergoes minimal oxidation, preserving its delicate flavor and high concentration of antioxidants. Black tea, on the other hand, is fully oxidized, resulting in a stronger flavor and higher caffeine content. Herbal teas are made from the leaves, flowers, or roots of various herbs and are naturally caffeine-free.
