Health studies link beverage temperature and consumption to cancer and bone density risks

Recent scientific studies have identified various health correlations related to the consumption of hot beverages like tea and coffee.

An Oxford University study involving nearly one million people found that regularly consuming beverages at temperatures of 65 degrees Celsius or higher is associated with a three-fold increase in the risk of esophageal squamous cell carcinoma. Researchers noted that consuming six or more hot drinks daily may further increase this risk, though they emphasized that these are observational findings showing correlation rather than direct causation.

Other research focusing on bone health has yielded different results. A study of approximately 9,700 older women suggested that tea consumption may be linked to slightly higher hip bone mineral density, potentially due to catechins. Conversely, excessive coffee consumption—defined as more than five cups per day—was associated with lower bone mineral density, particularly in women with higher alcohol intake.

Additionally, moderate coffee consumption has been linked to potential benefits, such as a lower risk of type 2 diabetes, liver disease, and Parkinson’s disease, though researchers advise moderation and emphasize the importance of calcium and vitamin D intake.
