Consuming black tea is associated with a lower risk of death

The study found that people who drank two or more cups of black tea a day had a 9 to 13 percent lower risk of dying.

Can drinking tea reduce the risk of death?

According to a prospective cohort study, drinking black tea may be associated with a slightly reduced risk of death. Those who drank two or more cups of tea a day had the lowest risk of death. The study was recently published in the journal Annals of Internal Diseases.

Tea is one of the most popular drinks in the world. Previous studies have found a link between tea drinking and a reduced risk of death in communities where green tea is the most consumed form of tea. In contrast, published studies in populations where black tea use is more widespread yield inconsistent results.

Using data from the UK’s Biobank, scientists from the National Institutes of Health conducted a study to investigate the links between tea consumption and death from any cause and cause-effect. They also looked at whether relationships differ depending on the use of common tea additives (milk and sugar), tea temperature, and genetic variants that determine how quickly people metabolize caffeine.

UK Biobank contains data on half a million men and women aged 40 to 69 who completed the basic questionnaire between 2006 and 2010. 85 percent declared drinking tea regularly, and 89 percent. was drinking black tea.

Participants who drank two or more cups of tea a day had a 9 to 13 percent lower risk of death compared with non-drinkers. The relationships were observed regardless of whether the subjects also drank coffee, added milk or sugar to tea, preferred tea temperature or genetic changes in caffeine metabolism. According to the authors, their findings suggest that tea, even at higher consumption levels, may be part of a healthy diet.
