A new study based on data from the British Biobank found that people who drink two or more cups of black tea a day have a 9-13% lower risk of death. An article about this was published in the Annals of Internal Medicine.
What’s particularly interesting is the data when adding milk or sugar to the tea – these additions had no effect. Similarly, with the temperature of the drink – it did not matter.
The researchers also noted that the results were the same regardless of the genetic variants that affect the metabolic rate of the caffeine found in tea. In other words, the correlation is about the same for everyone.
In this study, researchers used data from half a million men and women aged 40 to 69 reported, 85% of whom drink tea regularly. 89% of them love black. All subjects were surveyed from 2006 to 2010, and the observation lasted more than ten years.
Fernando Rodríguez Artalejo, professor of preventive medicine and public health at the Autonomous University of Madrid, called the study “a significant advance in this field.” According to him, most of these studies were carried out in Asia, where green tea is most popular, and there was little data on the use of black.
This article shows that regular consumption of black tea (the most widely consumed tea in Europe) is associated with modest reductions in overall mortality and especially cardiovascular mortality over 10 years in middle-aged adults.
It is noteworthy that more recently, similar work by Chinese scientists, also based on data from the British Biobank, proved a decrease in the risk of mortality with daily coffee consumption.
