BEIJING(The COW News Digital) Incorporating regular tea consumption into daily routines may play a protective role in long-term cardiovascular health. A extensive medical study published in the Journal of Internal Medicine reveals that individuals who regularly consume tea experience a significantly lower risk of developing major vascular and heart-related conditions compared to non-tea drinkers.
The scientific investigation drew data from the China Kadoorie Biobank, tracking a cohort of 485,934 adult participants across China over a mean follow-up period of 9.05 years. Throughout this monitoring timeframe, medical researchers documented 14,863 incident cases of various vascular diseases, encompassing conditions such as ischemic heart disease, cerebrovascular illness, pulmonary heart disease, and peripheral arterial issues.
Statistical analyses showed that habitual tea intake was linked to an overall 11 percent reduction in total vascular disease risk. Researchers observed a non-linear dose-response curve among weekly drinkers, noting that the lowest overall risk profile emerged among individuals consuming approximately 6 to 8 cups of tea per day.
Interestingly, the study pointed out notable variations based on the type, strength, and serving temperature of the beverage. Black tea exhibited a more consistent inverse association with vascular disease risks when compared to green tea variants. Furthermore, participants who drank tea brewed at a moderate strength demonstrated optimal risk reduction. Conversely, consuming “scalding hot” or extremely hot tea was associated with an elevated risk of vascular complications, emphasizing that beverage temperature plays a crucial role in health outcomes.
Beyond individual consumption factors, the authors highlighted the cumulative impact of overall lifestyle habits. The lowest vascular disease risk occurred when regular tea drinking was combined with a non-smoking status and high physical activity levels. These findings reinforce that while tea serves as a beneficial beverage, combining it with healthy habits offers the strongest defense against long-term cardiovascular illnesses.
