May improve gut health

According to research, the type of bacteria in your stomach may have a big impact on your health. Some bacteria in your stomach are favorable to your health, while others are not. Indeed, some research suggests that the kind of bacteria in your gut may play a crucial role in lowering your risk of certain health issues such as inflammatory bowel disease, type 2 diabetes, cardiovascular disease, obesity, and even cancer. Black tea polyphenols may help maintain a healthy gut by encouraging the growth of beneficial bacteria while suppressing the growth of harmful bacteria.

Furthermore, black tea may possess antibacterial characteristics that eliminate dangerous chemicals and boost gut flora and immunity by assisting in the healing of the digestive tract lining. However, further study is needed before drawing firm conclusions about the effect of black tea on immunological function.
