Tea is a pleasant, popular, socially accepted, economical, and safe drink that is enjoyed every day by hundreds of millions of people across all continents. Tea also provides a dietary source of biologically active compounds that help prevent a wide variety of diseases. It is the richest source of a class of antioxidants called flavonoids and contains many other beneficial compounds such as vitamins and fluoride. A growing body of evidence suggests that moderate consumption of tea may protect against several forms of cancer, cardiovascular diseases, the formation of kidney stones, bacterial infections, and dental cavities. Future research needs to define the actual magnitude of health benefits, establish the safe range of tea consumption associated with these benefits, and elucidate potential mechanisms of action.
茶是一种宜人、受欢迎、为社会所接受、经济且安全的饮品，各大洲数以亿计的人每天都在享用。茶还提供了具有生物活性化合物的饮食来源，有助于预防多种疾病。它是一类名为黄酮类抗氧化剂的最丰富来源，还含有许多其他有益化合物，如维生素和氟化物。越来越多的证据表明，适度饮茶可能预防多种癌症、心血管疾病、肾结石形成、细菌感染和龋齿。未来的研究需要确定健康益处的实际程度，确定与这些益处相关的安全饮茶范围，并阐明潜在的作用机制。
