Drinking tea can be considered a healthy habit but a recent study has revealed people who drink very hot tea are at a greater risk of developing oesophageal cancer.
A study published in the International Journal of Cancer and reported by the Cable News Network revealed tea lovers who usually consume their tea hotter than 60 degrees Celsius and drink more than 700ml per day have 90 oercent more chance of developing oesophageal cancer compared with those that take lesser quantity and cooler tempratures.
More than 50,000 people in Golestan, a province in Northern Iran were studied.
According to the study’s lead author, Dr Farhad Islami of the American Cancer Society, “Many people enjoy drinking tea, coffee, or other hot beverages. However, according to our report, drinking very hot tea can increase the risk of esophageal cancer, and it is, therefore, advisable to wait until hot beverages cool down before drinking.”
Although some previous studies had found a link between drinking hot tea and oesophageal cancer, this is the first time an exact temperature was highlighted.
The esophagus is a long tube through which swallowed food and liquids travel to reach the stomach.
The American Cancer Society estimates that 13,750 new cases of oesophageal cancer will be diagnosed in men and 3,900 new cases in women in the United States in 2019.
The researchers followed 50,045 people, aged between 40 and 75, for an average of 10 years between 2004 and 2017. They detected 317 new cases of oesophageal cancer during the period.
The study authors, however, said more research was needed on why drinking very hot tea could be associated with the higher risk of esophageal cancer.
