Study Links Hot Beverage Consumption to Esophageal Cancer Risk
A recent study reveals that drinking very hot beverages significantly increases the risk of esophageal cancer.
Hot drinks above 65°C are linked to higher cancer risk.
Participants preferring very hot drinks had over three times the risk of esophageal cancer.
Reducing beverage temperature could prevent many cancer cases annually.
A new study has found a concerning link between the temperature of hot beverages and the risk of esophageal cancer. Conducted by researchers from the University of Oxford, the research analyzed data from nearly a million participants in the UK, revealing that those who prefer their drinks at very high temperatures face a significantly increased risk of developing esophageal squamous cell carcinoma (SCC).
The International Agency for Research on Cancer (IARC) previously classified beverages served at temperatures above 65 °C (149 °F) as 'probably carcinogenic to humans.' This classification stemmed from earlier findings that linked the consumption of very hot mate, a traditional South American drink, to an increased risk of esophageal cancer. However, the impact of hot drinks at lower temperatures had not been thoroughly investigated until now.
In this extensive study, researchers gathered data from 977,282 participants, asking them about their hot drink preferences and consumption habits. The results indicated that individuals who enjoyed their beverages 'very hot' had a 3.17-fold higher relative risk of developing SCC compared to those who preferred their drinks 'warm.' Additionally, those consuming six or more hot drinks daily exhibited a 71% increase in cancer risk.
The implications of these findings are significant, suggesting that even a slight reduction in beverage temperature could prevent a considerable number of esophageal cancer cases. Researchers estimate that if individuals who typically consume very hot drinks switched to a lower temperature, approximately 14% of esophageal SCC cases could be avoided, translating to around 440 preventable cancers each year in the UK alone.
Despite the compelling nature of these findings, the study does have limitations, particularly regarding the lack of precise temperature measurements of the beverages consumed. Future research is needed to clarify these associations further. Nevertheless, the study highlights the importance of beverage temperature as a potential risk factor for esophageal cancer, emphasizing that it may be the heat rather than the drink itself that poses the greatest danger.
