New research, appearing in the International Journal of Cancer,finds an association between drinking tea at very high temperatures and the risk of developing esophageal cancer.
According to the American Cancer Society, in 2019, there will be approximately 17,650 new cases of esophageal Cancer and over 16,000 people will die from it.
Numerous factors may raise a person’s risk of developing cancer of the esophagus. These include being older than 55, being male, having acid reflux or eating a diet high in processed meats and low in fruits and vegetables.
Some researchers have also suggested that regularly drinking very hot liquids may also raise the risk of esophageal cancer.
The researchers divided tea temperature into “very hot” — meaning a temperature of over 60°C, and “cold [or] lukewarm,” that is, a temperature that is or falls below 60°C.
In their analysis, the researchers also considered a “reported shorter time from pouring tea to drinking” it — that is, on a scale between 2 and 6 minutes’ wait, as well as “reported preference for very hot tea drinking.”
Overall, the study found that drinking 700 milliliters (ml) of “very hot” tea per day increased the chances of esophageal cancer by 90 percent compared with drinking the same daily amount of cold or lukewarm tea.
“Our results substantially strengthen the existing evidence supporting an association between hot beverage drinking and [esophageal cancer risk],” conclude the researchers.null
