Think Twice Before Taking That Scalding Sip: Oxford Study Highlights Cancer Risk
Published on October 17 at 19:59
Scientists at Oxford University examined data from nearly one million UK participants and discovered a significant association between consuming very hot drinks and an increased risk of esophageal squamous cell carcinoma. Their findings, based on over 977,000 individuals from the Million Women Study and UK Biobank cohorts, were recently featured in the International Journal of Cancer.
The study revealed that people regularly drinking very hot beverages faced more than triple the risk (3.17 times) of developing this form of esophageal cancer compared to those who consumed warm drinks. Additionally, drinking hot drinks raised the cancer risk by 69%. Notably, consuming six or more cups daily increased the risk by 71%, regardless of the beverage's temperature.
Implications and Background
Back in 2016, the International Agency for Research on Cancer (IARC) classified drinks served above 65 °C as probably carcinogenic to humans. Animal experiments further showed that water hotter than 70 °C could cause precancerous damage and tissue death in the esophagus. According to the new study, switching from very hot to just hot drinks might prevent about 14% of esophageal cancer cases, equating to roughly 440 cases annually in the UK.
Temperature data for the drinks relied on participants’ self-reports. It's important to note this investigation is observational and does not establish a direct cause-and-effect relationship.
"It remains unclear whether these findings apply to the temperatures at which hot drinks are typically consumed in Western populations," commented Keren Papier.
These results emphasize the need for caution when drinking hot beverages, given the serious health implications connected to esophageal cancer risk. The study opens avenues for further research into how drink temperature affects human health and could influence future public health guidelines on beverage consumption.
While the link between extremely hot beverages and esophageal cancer is concerning, it's crucial to consider other lifestyle factors that may also impact health. For instance, a recent study from Oregon highlights how eating late at night can raise the risk of liver disease by 20-30%. Understanding these various health risks can help individuals make more informed choices about their daily habits.
