III. Expert Reminder: These 4 Types of Tea Are Truly Carcinogenic
Ruan Guangfeng, Deputy Director of the Science and Health Information Exchange Center, stated that these are the types of tea that should be consumed less frequently in daily life:
1. Strong Tea: Strong tea contains rich amounts of caffeine and tea polyphenols, which can cause strong irritation to the gastrointestinal tract, leading to symptoms such as nausea, vomiting, and diarrhea. Over time, it may also increase the risk of cancer.
2. Overheated Tea: Tea water with a temperature >65 degrees Celsius can scald the esophageal mucosa, and repeated scalding can significantly increase the risk of esophageal cancer. It is recommended to drink tea at a moderate temperature.
