黄酮类化合物可能预防心血管疾病发生。茶是黄酮的一个主要来源。研究表明红茶能改善血管内皮功能,但红茶对动脉血流动力学、血压和胰岛素抵抗的作用还不是很清楚[J Hypertens,2009,27(4):774-781]。可能由于研究设计或黄酮剂量测试的缺陷,研究结果还不一致。此外,还没有研究评
Flavonoids may prevent cardiovascular disease. Tea is a major source of flavonoids. Studies have shown that black tea can improve endothelial function, but the role of black tea on arterial hemodynamics, blood pressure and insulin resistance is still not clear [J Hypertens, 2009, 27 (4): 774-781]. The results may not be consistent, perhaps due to deficiencies in research design or flavonoid testing. In addition, there is no research review
