A new study published in the International Journal Of Cancer on March 20, 2019, showed people who drank extremely hot tea could almost double the risk of being stricken with esophageal cancer.
The study found people who drank tea hotter than 140 degrees Fahrenheit (60 degrees Celsius) and consumed more than 23 ounces (700 ml) had a 90 percent greater risk of developing esophageal cancer than those who drank the beverage at a cooler temperature at a lesser amount.
The study included over 500,000 people from Golestan in Iran, between 40 years old and 75 years old. The study participants were followed for ten years between 20014 and 2017. Three hundred seventeen of the participants developed esophageal cancer.
Dr. Farhad Islami, the leader of the study from the American Cancer Society said many people enjoy drinking hot beverages such as tea and coffee. The research shows that drinking very hot tea can increase esophageal cancer risk. The doctor advised waiting for beverages to cool before drinking.
Previous research on the subject also found a link between esophageal cancer and hot tea. The study published on March 20 pinpoints the exact temperature.
In the United States and Europe, tea is usually served at 149 degrees Fahrenheit (65 degrees Celsius.) However, in South America, Turkey, Iran, and Russia, it is common to consume tea hotter than that temperature.
Senior research associate at the University College London, Dr. James Doidge, said that it was well established hot drinks could increase the risk of developing esophageal cancer.
He said that a scientist or study is not necessary to know that if an individual repeatedly irritates a body surface, it can increase the cancer risk. Sunburn can give cancer, food and drink can contribute to gastrointestinal cancers, and smoking can contribute to lung cancer.
