Tea consumption linked to lower cardiovascular risk in large-scale study
A large-scale study involving approximately 486,000 participants has found that regular tea consumption is associated with an 11% lower risk of vascular diseases, including heart disease and stroke. The research, published in the Journal of Internal Medicine, tracked individuals over a nine-year period.
Key findings suggest that drinking six to eight cups of tea per day provides the greatest protection. Black tea showed a more consistent association with risk reduction than green tea, though both offer benefits. The study also noted that moderate tea strength was most effective, whereas extremely strong or very weak tea had less impact.
A significant warning was issued regarding beverage temperature: consuming tea that is “scalding hot” was linked to a 16% increase in cardiovascular disease risk. Additionally, separate research involving nearly one million people in the UK highlighted that very hot beverages can triple the risk of esophageal squamous cell carcinoma.
Experts emphasize that tea should be viewed as part of a broader healthy lifestyle. The benefits are most pronounced in individuals who also avoid smoking and maintain regular physical activity. Researchers cautioned that these findings are observational and that tea consumption alone is not a guaranteed preventative measure.
