摘要： The health effects of tea made from tender shoots of tea plant (Camellia sinensis) have been studied extensively. This review article assesses the evidence for the health effects of tea consumption in humans, using results from studies in animal models and in vitro as supportive evidence and for mechanistic understanding. The evidence is solid for the prevention of cardiovascular diseases, obesity, diabetes, and some types of cancer. The prevention of cognitive decline and muscle loss in seniors, as well as the antimicrobial, anti-inflammatory, and hypouricemic activities, are all promising topics for additional studies in humans. Most of these data were obtained from studies with green tea. Black tea and other types of tea have also shown some beneficial health effects. Comparative studies on the health effects of the six major types of Chinese tea have been conducted in animal models; however, no conclusive results can be projected to humans. The presence of sugar, artificial sweeteners, or refined starch, as well as flavoring agents and preservatives, in bottled or bubble tea beverages may cause health concerns in reducing or overshadowing the beneficial health effects of tea. Pesticide residues, heavy metals, and other contaminants in tea can be health concerns. However, risk assessment based on the levels of these contaminants in tea brews suggests that regular tea consumption should not pose a health risk. In summary, tea is a healthy beverage; consumers can select the tea types that they enjoy. Additional research would further elucidate the health benefits and assess some of the health concerns of tea consumption.
