Consuming Very Hot Drinks May Cause Esophageal Cancer
In June 2016, the International Agency for Research on Cancer (IARC) reported on their evaluation of studies of coffee, maté (a caffeine-rich tea drink made from steeping yerba mate [Ilex paraguariensis] ground-up leaves in hot water), and other hot beverages and their relationship to esophageal cancer.
The working group found no conclusive evidence that drinking coffee or maté causes cancer. However, the scientists did conclude from their studies that drinking very hot beverages of almost any type probably causes cancer of the esophagus in humans. Consequently, their results suggest that drinking very hot beverages is one possible cause of esophageal cancer. They concluded that drinking very hot beverages should be classified as probably carcinogenic to humans.
