vascular disease – a condition affecting blood vessels and the circulation of blood around the body

Example: Regular physical activity may help reduce the risk of vascular disease.

associate – to consider two things connected or related

Example: Researchers associated regular tea consumption with a lower risk of cardiovascular problems.

compound – a substance formed from two or more chemical elements

Example: Certain plant compounds may help protect cells against damage.

inflammation – the body's response to injury or illness, often involving swelling and pain

polyphenol – a natural chemical found in plants that may have antioxidant effects

Reading

Introduction

"Tea is enjoyed around the world, but researchers are investigating whether drinking it regularly could benefit heart health. However, its temperature and other lifestyle habits may also matter. Read and focus on the main ideas."

Article (All Levels)

A study from China suggests that drinking tea regularly may help protect the heart and blood vessels. Researchers studied almost 486,000 people over several years.

People who drank tea at least three days a week had a lower risk of heart disease and stroke than those who drank it less often.

However, drinking tea that is extremely hot was associated with a higher risk of vascular disease. Tea contains natural substances called polyphenols, which may help reduce inflammation.

The researchers explained that tea alone cannot guarantee good health. Exercise, not smoking, and other healthy habits are also important.

Developed Article (B1–C2)

A large study conducted in China suggests that regular tea consumption may be associated with a reduced risk of cardiovascular disease, including heart disease and stroke. Researchers examined data from almost 486,000 adults over an average period of nine years.

Participants who drank tea on at least three days per week had an 11% lower risk of vascular disease than those who consumed it less frequently. Black tea showed a more consistent association with lower risk than green tea, while moderate-strength tea was also linked to potential benefits.

However, participants who described their tea as "burning hot" had a 16% higher risk of vascular disease than those who did not regularly drink tea. One possible explanation is that extremely hot drinks may have harmful effects, although the study did not establish a direct cause.

Tea contains polyphenols, plant-based compounds that may help reduce inflammation, protect blood vessel cells, and support healthy circulation. Nevertheless, researchers emphasized that these findings do not prove that tea itself caused the differences in health outcomes.

Other confounding factors, including diet, physical activity, smoking, and existing health conditions, may also influence cardiovascular health. The findings therefore suggest that tea could form part of a healthy lifestyle, rather than serve as a substitute for other protective habits.
