High blood pressure (BP) is a leading risk factor contributing to the global burden of disease. Small changes in BP due to dietary modification may have a significant impact on the prevalence of hypertension and risk of cardiovascular disease.Tea is a popular beverage worldwide and is usually the major source of population flavonoid intake, often providing more than half of total intake.2 There is mounting evidence that tea and its flavonoids can make an important contribution to vascular health.3 However, the effects of regular consumption of black tea on BP remain unclear.
