Hot tea linked to esophageal cancer in smokers, drinkers

Hot tea is one of the most commonly consumed beverages around the world especially in the winter season as it can be of great help when trying to stay warm and fighting colds or soothing a sore throat.

Tea lovers, your cup of tea could put you at higher risk of developing cancer.

For the purposes of the study, excessive alcohol use was defined as the equivalent of slightly more than a 12-ounce glass of beer per day.

Canqing Yu, PhD, from the Peking University Health Science Center in China, and colleagues examined whether high-temperature tea drinking is associated with esophageal cancer risk in a prospective cohort established during 2004 to 2008.

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

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

Chinese scientists today released the findings of a large study that has detected what they say is a "noticeable increase" in the risk of esophageal cancer associated with a combination of hot tea drinking, excessive alcohol consumption and tobacco smoking.

As long as we drink these hot drinks at the service temperature of under 65 degrees and in moderate quantities, we'll be safe from any side effects.

Which is the optimal temperature for consumption?

This study has some limitations.

They said: "Abstaining from hot tea might be beneficial for preventing oesophageal cancer in persons who drink alcohol excessively or smoke".

"However, the results of this study should not cause people to abandon their favorite beverage", Dr. Kamminger wrote.

People were only asked about tea, alcohol and tobacco consumption at the start of the study. This cohort study of 456 155 participants based in China had a median follow-up of 9.2 years. The independent link between near-boiling tea and esophageal tumors is not yet clear.

Even in this sample, oesophageal cancer was relatively rare - and the absolute increase in risk from hot tea was quite small.

In comparison, boozers and smokers risk was just 2.5 times higher if they stuck to cooler drinks. The different disease development may be the result of different exposures and risk factors.

"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. Drinking tea is unlikely to be the biggest of their health problems.
