茶是世界上最受欢迎的饮料之一。人们享受消费,获得健康,普遍认为茶中生物活性物质可以使人体保持健康,免遭疾患。但当前的研究结果相互矛盾,要断定茶与人类健康的确切关系,证据不够充分,尤其是体外实验与临床结果的不一致,要明确阐述茶与人体的健康关系为时尚早。因此,需要更多的研究手段、研究技术和流行病调查,跨越饮茶的传统方式,采用更先进的方法,如纳米技术等,以求确凿的科学证据。
Tea is one of the most popular drinks in the world. People enjoy spending, get healthy, generally believed that bio-active substances in tea can keep the body healthy, from disease. However, the current research results are contradictory. To determine the exact relationship between tea and human health, the evidence is not sufficient, especially in vitro experiments and clinical results are inconsistent. It is too early to clearly explain the health relationship between tea and human body. Therefore, more research tools are needed to study techniques and epidemiological investigations, to cross the traditional way of drinking tea and adopt more advanced methods, such as nanotechnology, for conclusive scientific evidence.
