As International Tea Day approaches, new evidence suggests that the UK’s beloved drink—black tea, whether with milk or without—may be doing much more than simply providing a morning boost. Tea could be a natural ally in protecting heart health.
A recent poll of 1,000 adults, analysed by the Tea Advisory Panel, found that over three-quarters of Brits (76%) are concerned about their heart health, underscoring the widespread desire for easy, effective ways to safeguard wellbeing. Fortunately, one of the simplest habits for heart protection may already be brewing in your kitchen cupboard.
Dr Tim Bond, tea expert from the Tea Advisory Panel, explains: “Tea contains natural plant compounds called polyphenols, known for their range of cardiovascular benefits. These bioactive compounds support healthy blood vessel function, help maintain balanced cholesterol levels, and reduce inflammation—all critical for a healthy heart.”

Supporting these claims, a major study of more than 207,000 adults from the UK Biobank revealed that individuals consuming the highest levels of polyphenol-rich foods and drinks—including tea—had a 22% lower risk of developing heart disease. Additionally, a large-scale analysis involving nearly one million adults linked regular black tea consumption to a reduced risk of coronary heart disease. Researchers attribute this effect to flavonoids, a specific group of polyphenols abundant in tea.
There’s even more encouraging news for tea enthusiasts. Dr Bond notes, “Studies suggest heart health benefits can begin from as little as two cups daily, with each additional cup offering further cardiovascular support.” Conveniently, the average Brit already enjoys between four and five cups of tea every day, according to the Tea Advisory Panel’s survey.
However, how you brew your tea matters. “To maximize the benefits of tea’s polyphenols, it should be brewed for at least two minutes,” says Dr Bond. “A brief steep won’t release the same levels of heart-supporting compounds. Proper brewing ensures these nutrients fully infuse into your cup.”
Experts also recommend opting for freshly brewed unsweetened tea over sugary drinks. This simple switch can reduce sugar intake while increasing polyphenol consumption.
Despite growing scientific evidence, awareness remains low. The TAP survey found that two-thirds of respondents were unaware that tea polyphenols can help protect against heart disease and stroke, and only a quarter associated regular tea drinking with a lower heart attack risk.
Enjoying your daily cup of tea might just be a delicious way to nurture your heart health.
