Hot tea, combined with heavy smoking and alcohol use, increases cancer risk


Dr Canqing Yu and colleagues from the National Natural Science Foundation of China wrote in the journal Annals of Internal Medicine: 'Compared with participants who drank tea less than weekly and consumed fewer than 15g of alcohol daily, those who drank burning hot tea and 15g or more of alcohol daily had the greatest risk for oesophageal cancer'.

The researchers found that people who regularly drank hot tea, smoked and drank alcohol had the highest esophageal cancer risk.

Esophageal cancer kills approximately 400,000 people every year, according to the International Agency for Research on Cancer, cancer research arm of the World Health Organization.

The findings was based 456,155 Chinese men and women aged 30 to 79 who were followed for a median of 9.2 years. "Nevertheless, accumulating data suggest that drinking very hot tea may also increase the risk of esophageal cancer, and it may be prudent for people who drink very hot beverages to wait until it cools down a bit before drinking, whether or not they also smoke cigarettes or drink alcohol".

A new study has suggested that boiling hot tea has been linked to the increase in esophageal cancer.


'Most people drink their tea and coffee at a temperature that seems unlikely to cause cancer'.

But even those who don't touch alcohol or cigarettes appear to have a higher risk, researchers warned, but they stressed more tests are needed to assess how damaging it could be. But the authors speculate that hot tea may damage the tissue lining the esophagus, which could increase the chance of injury from other risk factors like smoking and drinking.

"If you go to the Middle East or to Russian Federation, they drink it out of a samovar that's constantly under heat", said Peter Goggi, president of the Tea Association of the USA. Do you agree? Do you drink your tea or coffee extra hot?

In the end, the researchers indicated 1,731 cases of esophageal cancer. The risk of this cancer is more in men than women.

At the beginning of the study, the people completed a lifestyle questionnaire that asked how frequently they consumed tea, how much they consumed, how they prepared the beverage and which type of tea they drank.

"Of course, keeping away from both tobacco and excessive alcohol use is the most important means for esophageal cancer prevention", she added.
