Having Piping-Hot Tea May Increase Cancer Risk
Tea is a common beverage across the globe. We all love to enjoy a warm cup of tea, be it summer or winter. A lot of us just gulp down a piping hot cup of tea in one go. But science says that tea lovers who do not let their beverage cool down a bit can be at the risk of developing esophagus cancer.
Why is it harmful?
A decade long study published in the International Journal of Cancer revealed that people who drank a lot of tea and mostly like to have it very hot- above 60 degrees- had double the risk of esophageal squamous cell carcinoma compared to the one who had cooler tea.
Even The World Health Organization’s International Agency for Research on Cancer has made it clear that drinking very hot beverage above 65 degrees C is “probably carcinogenic” for a human being.
What is esophagus cancer?
Esophagus cancer, also known as esophageal squamous cell carcinoma is the sixth most common cause of cancer death across the world. It occurs in the esophagus- a long, hollow tube that connects the throat to the stomach.
The study was published in the International Journal of Cancer in which around 50,000 adults living in the Golestan Province in northeastern Iran participated. This area was chosen for the study as a huge number of people staying over here are suffering from the problem of esophageal cancer and interestingly, they drink an average of 1,100 milliliters (about 37 ounces) of black tea daily.
In the study which was started in 2003 and concluded in 2017, researchers collected information about preferences for tea temperature. By 2017, it was found that almost 317 of all the people developed esophageal squamous cell carcinoma.
The researchers even took other factors like tobacco, alcohol or opium consumption in consideration during the study. Although more research is needed in this matter.
The research suggests that even though black and green teas have antioxidants, but there are other unknown compounds in the teas that can be harmful to the body when consumed hot. So, let your tea cool down for a while before having it.
