Research: This systematic review and meta-analysis of randomized controlled trials investigated the effect of black tea consumption on serum concentrations of total, LDL and HDL cholesterol. Researchers identified relevant literature in PubMed, Scopus and the Cochrane Library. Inclusion of studies, data extraction, quality assessment and meta-analysis were conducted according to the PRISMA statement.
Results: Ten eligible studies with 411 participants were identified. No significant heterogeneity was found between studies. Consumption of black tea significantly reduced LDL cholesterol concentration (−4.64 mg/dL; 95% CI: −8.99, −0.30 mg/dL; P = 0.036). No remarkable change was detected in total cholesterol (−2.04 mg/dL; 95% CI: −6.43, 2.35 mg/dL; P = 0.363) or HDL cholesterol (−1.15 mg/dL; 95% CI: −3.04, 0.75 mg/dL; P = 0.236). Subgroup analysis showed that the lowering effect on LDL cholesterol was more effective in subjects with higher cardiovascular risk.
Researchers concluded that black tea consumption significantly lowered serum concentration of LDL cholesterol, especially in subjects with higher cardiovascular risk. Black tea intake did not impose obvious effect on serum concentrations of total and HDL cholesterol.
