  • 绿茶和白茶目前逐渐开始全球化。
  • 儿茶素最为关注,特别是EGCG;其强抗氧化能力对退化性疾病有一定防治作用。
  • 没食子酸、咖啡因、茶碱、茶氨酸等功能成分和微量营养素也得到了关注。
  • 茶叶在调节血压、预防心血管疾病和2型糖尿病、体重控制、增加骨密度、降低癌症风险等方面的作用,获得一些研究证据支持。
  • 未来需要高质量的人群干预试验和流行病学研究论证茶叶功效;并研究儿茶素等成分的分子机制、吸收和生物转化过程。

Abstract:收起
Green tea has been consumed for centuries in Japan, China and Morocco. White tea, which is considered a variety of green tea, is mostly consumed in China and is very appreciated for its flavor. Currently the consumption of both types of tea has been extended to the western countries even as a functional ingredient. A group of polyphenols called catechins stands out among their bioactive components, the most abundant being the (-) epigallocatechin gallate, with high antioxidant power. Teas also contain other phenolic compounds such as gallic, caffeic, chlorogenic or cinnamic acids, quercetin and proanthocyanidols, caffeine, theophylline, l-theanine and minerals such as fluorine, manganese or chromium. Investigations have mainly been focused on their antioxidant potential and their implication in the prevention and treatment of degenerative diseases. Several studies have evaluated their role in cardiovascular diseases, body weight control, bone mass increase, protection against neurodegenerative diseases and improvement of type 2 diabetes, among other pathologies. The main points of controversy are the design and interpretation of epidemiological and human intervention studies and the lack of information on catechins availability, metabolism and biotransformation. This review compiles and analyzes the latest peer-reviewed papers published from 2002 up to February 2017, including systematic reviews and meta-analyses.
