The study featured 500,000 men and women aged 40-69 in the UK Biobank. Nearly 90 percent said they drink tea.
Researchers found that those who claimed to drink two or more cups per day of back tea reduced their risk of dying by 9 to 13 percent. It also made no difference whether they took it with milk or sugar or drank coffee as well.
Even in high amounts, tea may be part of a healthy diet. And yet this may offer some reassurance for those that drink black tea, but it does not necessarily mean that those who don’t should immediately begin.
The benefits of black tea may be related to antioxidant compounds, like polyphenols and flavonoids, found within it. These compounds, particularly a type of polyphenol called catechins, may have protective effects.
Of course, tea alone is unlikely to make somebody healthier or allow them to live longer. It won’t counteract the effects of an unhealthy diet or lifestyle, for example, but it may amplify the effects in those already eating and living healthy.
When looking at health and longevity, it is essential to pay attention to the diet as a whole, making sure you’re eating plenty of food that promotes an anti-inflammatory response.
People are likely to benefit most when tea is part of a diet that is already rich in fruits, vegetables, healthy fats, and other heart-healthy, anti-inflammatory foods.
This is not the first study to highlight the potential health benefits of tea. Both black and green tea, which is also a rich source of antioxidants, may help extend life as part of a healthy lifestyle.
