Drinking tea can keep you healthy, but drinking too much tea is not only beneficial, but also harmful to your stomach and body.

Regarding the harm of tea to health, we must start with the characteristics of tea. Tea polyphenols in tea combine with glycoprotein in oral mucosa to produce a sense of convergence. Tea polyphenols can combine with protein of oral mucosa and destroy oral mucosa, so the more astringent the tea soup, the greater the damage.

Let's look at the characteristics of the human body. Human food pipelines are protected by mucosa, and mucosal proteins in mucosa are easily destroyed by high concentration of tea polyphenols. Therefore, drinking tea on an empty stomach or astringent tea soup will hurt the stomach.
