Drinking six cups of black tea daily may boost heart and vascular health, study finds

A new scientific study has found that regularly drinking black tea can lower the risk of cardiovascular disease by up to 11% compared to those who do not consume tea.

The study, published in the Journal of Internal Medicine, highlighted the role of tea in supporting circulatory system health.

Analysis of consumption levels showed that the lowest estimated risk was recorded among participants who drank between six and eight cups of tea daily, suggesting a possible link between the amount consumed and the level of protection.

The research team examined the combined relationship between tea consumption, smoking, and physical activity levels. They found that the lowest risk appeared among individuals who regularly drank tea, did not smoke, and engaged in high levels of physical activity. The study also noted that drinking tea of moderate strength was associated with the lowest risk compared to other strengths, indicating that preparation methods may play an important role in the relationship between tea consumption and vascular health.

The results showed that black tea had a more consistent inverse association with vascular disease risk than green tea, suggesting that the health effects may differ depending on the type of tea and its composition.

A previous study involving half a million tea drinkers in the United Kingdom also found that high tea consumption was linked to a slight reduction in mortality risk.
