Tea consumption linked to lower vascular disease risk

A large-scale observational study involving nearly 486,000 adults in China has found that regular tea consumption is associated with an 11 percent lower risk of developing vascular diseases, including cardiovascular and cerebrovascular conditions.

The research, published in the Journal of Internal Medicine, tracked participants aged 30 to 79 for approximately nine years. Key findings suggest that black tea may offer greater protection against various vascular diseases compared to green tea, potentially due to bioactive compounds like theaflavins which possess anti-inflammatory properties.

Consumption patterns significantly impact health outcomes. The study identified an optimal intake of approximately six to eight cups per day, noting that the lowest risk was observed at this level. However, excessive consumption—around 20 cups daily—was associated with increased risks, likely due to high caffeine intake.

Temperature and preparation also play critical roles. Participants who consumed tea at very high temperatures faced a 16 percent higher risk of vascular disease compared to those who did not. Additionally, tea brewed at a moderate strength showed more positive results than extremely strong or weak varieties.
