There recently was a study done that linked drinking tea while too hot may lead to esophageal cancer if you also smoke or drink alcohol. Also acid reflux can play a part in this. This study was printed in the Annals of Internal Medicine.
According to the International Agency for Research on Cancer, a part of the World Health Organization, this cancer is the eighth most common cancer worldwide. There is low survival rate for this cancer. Approximately 400,000 do not survive this cancer annually.
So to conclude, let your tea (or coffee) cool down before drinking it. Or switch to iced tea or cold brew!
Last summer the World Health Organization announced that regularly drinking coffee may prevent cancer. This is a reversal of the WHO’s position 25 years ago. Previously the organization had cautioned the beverage might be carcinogenic.
However, the WHO still warns that very hot beverages, around 160 degrees Fahrenheit, are still believed to cause cancer. This is about 10 degrees hotter than the average U.S., U.K. or European drinker prefers coffee, tea and other hot beverages. It is closer in temperature to the temperature at which South Americans and the Chinese drink maté or tea.
While the question of whether or not coffee is healthy for us has been going on for quite a long time, these days the health benefits warrant their own Wikipedia page. In this case conventional wisdom aligns nicely with the current research of the medical community.
