Tea consumption linked to lower vascular disease risk
A large-scale observational study published in the Journal of Internal Medicine has found that regular tea consumption is associated with an 11.2% reduction in the risk of vascular diseases, including stroke, coronary heart disease, and myocardial infarction.
The study tracked 485,934 adults in China over a median period of nine years. Researchers noted that the strongest protective effects were observed for ischemic stroke, which saw a 36.6% risk reduction, and cerebrovascular diseases, which decreased by 19.1%.
Key findings regarding tea consumption include:
• Type and Strength: Black tea showed a more consistent association with lower vascular risk than green tea. Additionally, tea of moderate strength was linked to better health outcomes.
• Quantity: While the median consumption was two to three cups daily, the lowest estimated risk was observed among those drinking six to eight cups per day. However, researchers cautioned that this is not a formal daily recommendation.
• Temperature: Drinking tea at scalding hot temperatures was associated with a 16% higher risk of vascular disease compared to non-regular drinkers, suggesting that consumption temperature is a critical factor.
Experts emphasize that while the bioactive compounds in tea, such as polyphenols and flavonoids, offer antioxidant and anti-inflammatory benefits, these findings are observational and do not prove that tea directly prevents disease.
