Hot tea increases the risk of cancer of esophageal cancer from alcohol and cigarettes
For many people, there is hardly anything better than a nice hot cup of tea when you want to relax. However, the temperature of the drink should not be too high. A new study showed that hot tea increases the risk of cancer from smoking and alcohol consumption.
Tea has long been known for its beneficial effects
Tea has long been known for its beneficial effects. Many people can relax with it. Some teas can also help you lose weight, and some can even prevent illness. Green tea in particular is very healthy. Studies with animals have even shown that it can potentially protect against cancer. However, tea should apparently not be drunk too hot, otherwise it increases the risk of esophageal cancer from alcohol and smoking. Researchers from China have now found that out.
Do not drink hot drinks too hot
Scientists from the United States reported a few months ago about a study that showed that hot black tea can protect our eyes. This reduces the risk of glaucoma (glaucoma).
The International Agency for Research on Cancer (IARC) of the World Health Organization (WHO), however, came to the conclusion in an older study that the temperature of drinks should not be too high, since very hot drinks can be carcinogenic.
The study results "suggest that the consumption of very hot drinks is a likely cause of esophageal cancer and that the temperature, rather than the drinks themselves, appear to be responsible," said IARC Director Dr. Christopher Wild, then.
A Chinese research group is now reporting similar results. In a study published in the journal "Annals of Internal Medicine", the scientists found that consuming hot tea increased the risk of esophageal cancer from smoking and alcohol consumption.
Increased risk of esophageal cancer from alcohol and smoking
As the specialist magazine "Eurek Alert!" Reports, esophageal carcinomas (esophageal cancer) are increasing in frequency and have poor survival rates.
China is one of the countries with the most cases of esophageal cancer. Tea drinkers, especially Chinese men, smoke and drink alcohol more often.
Both alcohol and tobacco use are considered risk factors for esophageal cancer.
Chinese researchers have now analyzed data from subjects who participated in the China Kadoorie Biobank (CKB) study to determine whether drinking very hot tea was associated with an increased risk of esophageal cancer.
This did not apply to data from people who had previously had cancer or reduced their tea, alcohol or cigarette consumption.
A total of 450,000 adult Chinese from ten regions participated in the study. After around nine years, more than 1,700 participants were newly diagnosed with cancer.
Hot tea in combination with alcohol and cigarette consumption increases the risk of cancer
"Drinking high-temperature tea in combination with either alcohol consumption or smoking was associated with a greater risk of esophageal cancer," the study authors write.
Study participants who drank hot tea every day and were smokers were twice as likely to develop esophageal cancer as non-smoking tea abstainers.
Tea drinkers who consumed at least 15 grams of alcohol a day in addition to cigarettes even had a five-fold increased risk of esophageal carcinoma.
According to the researchers, those who drank tea regularly but kept their hands off of cigarettes and alcohol had no increased risk of developing cancer.
"According to the authors of the study, these results indicate that avoiding hot tea can be beneficial for people who drink or smoke excess alcohol," says the journal "Eurek Alert!"
The respective results refer to male study participants. Women were generally less likely to fall ill. This could have to do with the fact that they rarely drink their tea very hot and also hold back more when consuming alcohol and tobacco. (ad)
