Stroke is a leading cause of morbidity and mortality in many countries. Green tea is a simple and inexpensive beverage that is showing promise in the prevention of several diseases, including stroke. However, epidemiological studies examining the preventive effects of tea on stroke have generated inconsistent results.
To review the emerging evidence for green tea in stroke prevention.
Published articles were located by searching the PubMed, ProQuest, CINAHL and other databases, using the keywords 'tea' and 'stroke' with no restriction on publication date. Reference lists of identified articles were also searched for relevant publications.
Two published epidemiological studies on green tea reported positive findings. A large number of studies have also proposed biological mechanisms by which tea or tea components may reduce the stroke risk. Additional studies are required from a variety of populations, assessing duration and different types of tea consumption on subtypes of stroke to provide further evidence.
Green tea is a safe and cheap beverage. Its consumption should be encouraged because it could potentially serve as a practical method for stroke prevention.
在许多国家，中风是发病和死亡的主要原因。绿茶是一种简单且价格低廉的饮品，在预防包括中风在内的多种疾病方面显示出前景。然而，关于茶对中风预防作用的流行病学研究结果并不一致。
综述绿茶在预防中风方面的新证据。
通过检索PubMed、ProQuest、CINAHL及其他数据库，使用关键词“茶”和“中风”，对发表日期无限制，以查找已发表的文章。还检索了已识别文章的参考文献列表以获取相关出版物。
两项已发表的关于绿茶的流行病学研究报告了阳性结果。大量研究也提出了茶或茶成分可能降低中风风险的生物学机制。需要来自不同人群的更多研究，评估饮茶持续时间和不同类型的茶对中风亚型的影响，以提供进一步的证据。
绿茶是一种安全且廉价的饮品。应鼓励饮用绿茶，因为它有可能成为预防中风的实用方法。
