Abstract

The objective of this study is to test the hypothesis that drinking tea has favourable effects on cardiovascular disease risk, and ability to cope with psychological stress. The study is a randomised controlled trial of tea versus matched placebo carried out over six weeks. Assessments will be made at the commencement of the study, after a four-week washout period, and after six weeks of tea or placebo. Measures will be obtained of blood pressure, heart rate, platelet activation, vascular adhesion molecules, inflammatory cytokines, haemostatic factors and mood, both at rest and in response to standard psychological stressors. Cortisol will be measured repeatedly over the working day using saliva sampling. The results will have implications for understanding the influence of tea on behavioural and biological responses relevant to health, and for consolidating a market advantage for the UK beverage industry.
