Tea consumption and risk of ischaemic heart disease

Li X, Yu C, Guo Y, et al. - Heart 2017; published online ahead of print

Background

Polyphenols, particularly flavonoids, are ingredients of tea and have antithrombotic and anti-inflammatory properties. They also inhibit oxidative reactions, reverse endothelial dysfunction, and prevent or delay atherosclerosis [1]. Studies evaluating the association between tea consumption and risk of ischemic heart disease (IHD) have resulted in conflicting conclusions [2,3]. However, these studies were small and low-powered.

In this study, the association of regular tea consumption with the risk of IHD was prospectively examined in 0.5 million adults included in the China Kadoorie Biobank (CKB) study [4,5].

Main results

Conclusion

In a large prospective cohort of Chinese adults, daily tea consumption was associated with 8% relative risk reduction in IHD, compared to never drinking tea. These findings confirm the protective effect of tea consumption on IHD.
