Drinking Hot Tea Can Increase the Risk of Esophageal Cancer
A new study conducted on February 5, 2018 reveals that drinking hot tea can be associated with a 5-fold increased risk for esophageal cancer.
Studies have found that consumption of hot tea at high temperatures can increase the risk of esophageal cancer in people who smoke cigarettes and consume alcohol. 450,000 participants were included in the study. Survival rates are poor in people who suffer from esophageal cancer. This cancer is highly prevalent in China as there are many tea drinkers who also consume alcohol and smoke. Tobacco, alcohol, chemical compounds present in these and the hot tea is found to complicate the relation between drinking tea and risk of cancer.
Participants who had enrolled in the China Kadoorie Biobank (CKB) were surveyed by the researchers to carry out a study. 456,155 participants between the age of 30 and 79 were included in the study. A strong relation was found between hot tea consumption and esophageal cancer along with consumption of alcohol and smoking. Compared to the participants who did not have any of these habits, a 5 times higher risk of esophageal cancer was observed in participants who consume hot tea, drink alcohol and smoke. However, absence of these habits were not related to the risk of cancer.
According to the study authors, these findings suggest that abstaining from hot tea may be beneficial for persons who drink alcohol excessively or smoke. Researchers suggest that people who consume alcohol and smoke should abstain themselves from consuming hot tea. Therefore, people who are fond of drinking tea can switch to herbal tea, which has many health benefits. This will increase the growth of herbal tea market, as detailed in the herbal tea market report published by Coherent Market Insights.
