People who regularly drink tea are more likely to have esophageal cancer. Research by Iranian scientists has confirmed the doubts of experts since 2016.
There are several factors that increase the risk of cancer. Drinking, smoking and overweight are one of the factors that increase the risk of cancer and is not surprising. However, researchers from Tehran University in Iran have found that this is another risk-increasing beverage.
According to a comprehensive study conducted, people who regularly consume hot beverages more than 60 degrees are more likely to develop esophagus, ie esophageal cancer.
Iranian researchers have watched more than 50,000 men and women in the 13-year period between 2004 and 2017 in the Gülistan province of Northern Iraq. During this period, the type of esophageal cancer was found in 317 cases.
Scientists have found a 90-percent correlation between the risk of esophageal cancer and consumption of 700 ml or more per day of tea with a temperature of at least 60 degrees.
In South America, Asia and Africa, the risk is higher
The work of the University of Tehran confirms longstanding suspicions. In 2016, the International Cancer Research Agency (IARC) rated excessive consumption of hot potions as a possible cancer.
Specifically, the organization referred to traditional teas that were consumed at very high temperatures, especially in beverages consumed at 65 degrees Celsius and especially in the continents of South America, Asia and Africa.
Does it mean that tea poses a great danger to raucous drinks or cigarettes that are known to increase the risk of esophageal cancer?
It really depends on where you live. That's exactly what they said in the Carpathian study. However, the American Cancer Society (ACS), on the other hand, points out that hot beverages such as tea, coffee and cocoa in the US usually drink at temperatures below 65 degrees.
According to the Germans, tea is not a risk
German experts do not see hot drinks as a basic risk. Thomas Seufferlein, medical director of the Ulm Clinic for Internal Diseases at Ulm University Hospital in Baden-Württemberg, treated patients diagnosed with esophageal cancer for 20 years. Seufferlein says the consumption of hot drinks has not recorded esophageal cancer cases.
No persuasive evidence yet
Seufferlein emphasizes that there is no need to worry about the consumption of hot tea in Germany at this time. "In Germany alcohol and cigarettes are often not consumed, but people who suffer from esophageal cancer due to the consumption of hot drinks are certainly an exception." It is useful to emphasize that tea is consumed colder than the usual temperature is less harmful than drinking hot tea. Due to the cooking of drinks the pain of the esophagus of the esophagus. "In these cases, there is a chronic heat-induced damage," says Seufferlein.
These errors can cause mutations when they appear in cell division. Simply put, cancer cells appear in this way. The medical director also emphasizes that there is still uncertainty about the process of damage to hot pancreas. But for now, waiting for the tea to cool off before you drink, it seems to be the smartest move.
