Drink Hot Tea and it May Lead to Cancer
By Kirsten Whittaker
Drinking black tea heated to temperatures above 70ºC (that's 158ºF) is a tradition in the
This might help to explain the increased esophageal cancer risk in some non-Western, tea drinking populations.
The thing they all have in common however is tea drinking, and this case controlled study looked for an association between how people drink their tea and the risk of esophageal cancers.
The subjects in the study drank black tea regularly, on average over a liter a day, though the amount of tea they drank didn't have any association with cancer risk.
What the team found was that compared to drinking lukewarm tea (65ºC or less), drinking hot tea (65º-69ºC) was linked to two times the risk of esophageal cancer, while drinking very hot tea (70ºC or more) was associated with an eight times higher risk.
Drinking hot tea within two minutes after it was poured was linked to a five times higher risk of cancer as compared to drinking more slowly. This study should not be seen as only related to drinking hot tea.
