According to the information that was compiled, participants who drank 700ml of tea (or around 24 ounces) per day had a 90% greater chance of having esophageal cancer when the tea was hotter than 60 degrees Celsius (140 degrees Fahrenheit). But those who drink it piping hot could be increasing their risk of esophageal cancer, according to a new study.
TEHRAN: Avoid taking hot tea to protect against oesophageal cancer as research has found that regularly swallowing hot drinks almost doubles the risk of developing diseases of the gullet and researchers have advised people to allow beverages to cool.
For the study, over 50,000 people in the Golestan region of Iran were examined over ten years.
"Many people enjoy drinking tea, coffee, or other hot beverages", Dr. Islami said. All in all, 317 new cases of ESCC (esophageal squamous-cell carcinoma, one type of esophagus cancer) were identified during the study, which followed up with participants at a median duration of 10.1 years.
In the US and Europe, hot drinks are typically served at lower temperatures. For so man people in Ireland, drinking tea in Ireland is a way of life and quite a healthy habit. Then, they were given a cup of scalding hot tea and asked to tell researchers when the tea reached their preferred temperature as it cooled down.
"As there is no known health benefit from drinking very hot beverages, it will be reasonable to advise people in Golestan and elsewhere to wait for their hot beverages to cool down before drinking", the researchers concluded, though they noted more research is needed.
The American Cancer Society estimates over 13,750 cases of esophageal cancer will come to light in men this year, with a further 3,900 new cases in women.
Last year, a Chinese study found that regularly drinking hot tea could multiply by five the risks of developing esophageal cancer.
