普洱茶减肥、降脂机制的探讨

普洱茶(Pu-erhtea)产于云南省南部地区,具有悠久的发展历史和丰富的文化涵蕴,被认为具有减肥、降脂、降血糖、防止心脑血管疾病等代谢性疾病功效。近几年来在人、啮齿类和细胞水平的研究表明,普洱茶的确具有减肥、降脂功效,普洱茶中的茶色素、多糖、多酚和他汀类物质可能通过抑制脂肪合成、促进脂肪氧化分解而发挥其减肥、降脂功效。本文综述了目前关于普洱茶减肥、降脂的生物学功效、活性成分、以及作用机制的相关报道,同时探讨了该领域未来的一些研究方向。

The mechanisms of weight-cutting effect and bioactive components in Pu-erh tea

Originally grown and produced in southern of Yunnan, China, Pu-erh tea has a long history and carries rich cultural connotations. Consumption of Pu-erh has been thought to possess numerous health benefits including weight-loss, lowering of blood glucose levels, and preventing cardiovascular diseases. Research on humans, rodents, and cell lines have each confirmed that Pu-erh tea indeed displays weight-loss and blood lipid lowering effects. The main bioactive components, such as theabrownin (TB), polysaccharides, polyphenols, and statins, may down-regulate the biosynthesis of fat and up-regulate the oxidation of fat to cut weight and reduce the content of lipids in blood. Here, we summarize current progress on understanding the mechanisms and bioactive components of Pu-erh's weight-cutting effects as well as highlighting current weaknesses in the field in order to suggest possible solutions for future research on Pu-erh tea.
