Link Found Between Very Hot Tea and Esophageal Cancer

Esophageal Cancer

Drinking a minimum of 700 ml of very hot tea is associated with a 90 percent higher risk of esophageal cancer. This is the result of a large survey among more than 50,000 people from Iran, who have been followed on average for 10 years. The research is published in the International Journal of Cancer .

Hot drinks

A link has often been found between the consumption of hot drinks and the risk of esophageal cancer. In this study, for the first time, the temperature of the tea was actually measured when consumed. The research was conducted in northeastern Iran, where residents are used to drinking tea very hot and where esophageal cancer occurs relatively often. It's there on the 2 eplace of the most common types of cancer (after breast cancer in women and stomach cancer in men). In the Netherlands, esophageal cancer less common : it is on the 9th e instead of more common cancers. Only 2 percent of cancer cases in the Netherlands concern esophageal cancer. Incidentally, tea is becoming common in Europe and the United States not as hot  as in the Middle East.

Drinking quickly is also disadvantageous

In the study, drinking tea at a temperature of more than 60 o Celcius was accompanied by 41 percent more chance of esophageal cancer than drinking tea less hot. Drinking tea quickly also proved unfavorable for the risk of esophageal cancer. Participants who drink a cup of tea within 2 minutes are 51 percent more likely to have esophageal cancer than participants who take more than 6 minutes.

Damage to the esophagus

The researchers think that very hot drinks damage the esophagus, which increases the risk of cancer. They recommend that hot drinks cool slightly before consumption.
