Drinking tea while it’s too hot may increase chances of developing esophageal cancer, a new health study suggests.
As per the new research study, excessive drinking of hot tea by smokers and alcoholics may lead to high esophageal cancer risks. Fortunately, people who are non-smokers and non-alcoholic drinkers can have their cup of tea without having to worry about any health issues, as the absence of alcohol and nicotine eliminates the risk of cancer.
For the purpose of the study, the researchers examined data from an ongoing population study known as the China Kadoorie Biobank study. They collected physical measurements and health-related questionnaires from more than half a million adults living throughout China from 2004 to 2008.
Ever since then, it’s kept track of their health outcomes. The researchers focused on some 400,000 people free of cancer at the start of the study. At the end of the study, it was found that there were 1,731 people who were diagnosed with esophageal cancer by 2015.
The health study found that the study participants who drank at least one beer, cocktail or glass of wine daily, and also consumed burning hot tea every day were 5 times more likely to develop oesophageal cancer than people who drank tea at any temperature less than once a week. Similarly, chain smokers who drank burning hot tea daily were twice as likely to develop cancer. Notably, both drinking and smoking are already known risk factors for that type of cancer.
“Drinking hot tea contributed to cancer only when it clustered with smoking and drinking alcohol excessively,” said lead author Jun Lv, Professor at Peking University in Beijing.
The study was funded by National Natural Science Foundation of China and National Key Research and Development Program. The results have been published in the journal Annals Of Internal Medicine.
