A large-scale study involving nearly 486,000 adults has found that regular tea consumption is associated with an 11 percent lower risk of cardiovascular disease, including heart attacks and strokes. Researchers observed that the protective effect was most pronounced among those who drank approximately six to eight cups daily, suggesting a dose-dependent relationship between tea intake and heart health. The findings, drawn from a substantial cohort, add to a growing body of evidence linking tea drinking to cardiovascular benefits.
However, the study carries a notable caveat: black tea demonstrated more consistent benefits than green tea, a finding that surprised researchers given green tea's reputation for higher antioxidant content. Scientists caution that the observational nature of the research means it cannot establish causation, and factors such as lifestyle, diet, and socioeconomic status may influence results. They also warn that consuming six to eight cups daily may not suit everyone, particularly those sensitive to caffeine. Further clinical trials are needed to confirm the mechanisms behind tea's apparent protective effects on the heart and blood vessels.
