茶是一种由茶树叶制成的受欢迎的饮料，近几十年来一直被广泛研究，因为它在预防肥胖、代谢综合征、糖尿病、癌症和其他疾病方面具有有益的健康作用。虽然这些有益的影响已经在大多数实验室研究中得到了令人信服的证明，但人类研究的结果并不一致。一些研究表明，只有每天饮用3-4杯茶(600-900毫克茶儿茶素)或更多的人才能观察到体重减轻、代谢综合征缓解和糖尿病风险降低。本章回顾了其中的一些研究，茶叶成分可能的作用机制，以及将实验室研究外推到人类情况的挑战。
Tea, a popular beverage made from leaves of the plant Camellia sinensis, has been studied extensively in recent decades for its beneficial health effects in the prevention of obesity, metabolic syndrome, diabetes, cancer, and other diseases. Whereas these beneficial effects have been convincingly demonstrated in most laboratory studies, results from human studies have not been consistent. Some studies demonstrated that weight reduction, alleviation of metabolic syndrome and risk reduction in diabetes were only observed in individuals who consume 3–4 cups of tea (600–900 mg tea catechins) or more daily. This chapter reviews some of these studies, the possible mechanisms of actions of tea constituents, and the challenges in extrapolating laboratory studies to human situations.
