Key Takeaways
- Regular tea consumption may lower the risk of vascular diseases by 11%.
- The type, strength, and temperature of tea may affect its health benefits.
- Black tea may have more consistent associations with reduced risk of vascular disease than green tea.
- Drinking tea at extremely high temperatures may increase the risk of vascular disease.
- Regular physical activity and not smoking may also contribute to reduced vascular disease risk.
Who benefits from regular tea consumption?
Regular tea consumption may offer important benefits for your heart and blood vessels, according to a massive study involving nearly 500,000 adults in China.
The study found that people who consumed tea regularly had a lower risk of developing several vascular diseases compared with those who did not drink tea.
What the study reveals about tea and vascular health
The researchers recorded 14,863 cases involving several types of vascular disease, including cardiovascular disease, cerebrovascular disease, pulmonary heart disease, and peripheral artery disease.
Although these conditions affect different parts of the body, they share an important feature: they interfere with the circulation of blood, which delivers oxygen and nutrients to organs and tissues.
By the numbers
- 485,934 adults in China participated in the study.
- 9.05 years was the median follow-up period.
- 14,863 cases of vascular disease were recorded.
- 11% lower risk of vascular disease was associated with regular tea consumption.
Black Tea vs. Green Tea: Does the type matter?
Black tea showed more consistent associations with a reduced risk of vascular disease than green tea.
Both black and green tea come from the same plant, Camellia sinensis, but they undergo different processing methods.
Tea strength and temperature: important considerations
Participants who drank tea of moderate strength had the lowest associated vascular disease risk, suggesting that stronger tea was not necessarily linked to greater benefits.
Drinking tea described as 'burning hot' was linked to an increased risk of vascular disease.
Tea, exercise, and smoking habits: a collective association
The researchers found that people who regularly drank tea, were not current smokers, and maintained high levels of physical activity had the lowest vascular disease risk.
Regular physical activity supports cardiovascular health in several ways, including improving circulation, helping regulate blood pressure, and supporting the function of the heart and blood vessels.

Readers can consider incorporating moderate tea consumption into their daily routine, while also being mindful of the type, strength, and temperature of their tea.
What to watch next
Further research is needed to determine whether tea consumption directly influences disease risk and to explore the biological mechanisms behind the observed associations.
Readers can stay informed about the latest developments in the field of tea consumption and heart health by following reputable sources and staying up-to-date with new studies and findings.
Expert perspective on tea consumption and heart health
Experts suggest that the antioxidant properties of tea, particularly polyphenols, may play a role in reducing the risk of vascular disease.
However, more research is needed to fully understand the relationship between tea consumption and heart health.
Timeline of tea consumption research
The study is part of a growing body of research on the health benefits of tea consumption, which dates back to the 1990s.
Future studies will continue to explore the relationship between tea consumption and heart health, including the potential benefits and risks of different types of tea.
Frequently Asked Questions
What is the recommended amount of tea consumption per day?
The study suggests that drinking 6-8 cups of tea per day may be associated with the lowest risk of vascular disease.
Is black tea or green tea better for heart health?
The study found that black tea showed more consistent associations with reduced risk of vascular disease than green tea.
Can drinking tea at high temperatures increase the risk of vascular disease?
Yes, the study found that drinking tea described as 'burning hot' was linked to an increased risk of vascular disease.
