Researchers have highlighted the positive effects of coffee and tea in reducing the risk of head and neck cancer. But did you know that their excess can also cause cancer?
Tea or coffee is consumed by millions of people around the world every day and it may play a protective role against certain cancers.
A new study published in the American Cancer Society’s journal Cancer shows that these two popular drinks reduce the risk of head and neck cancer, which accounts for 6% of all cancers worldwide.
Researchers analyzed data from 14 international studies that included nearly 25,000 participants. Participants provided information on their daily, weekly, monthly or annual coffee or tea intake, with which the researchers analyzed their health outcomes.
The results revealed that drinking more than four cups of coffee per day reduced the overall risk of head and neck cancer by 17%.
However, on the other hand, drinking more than one cup of tea per day increases the risk of laryngeal cancer by 38%.
