10Prevent Infections
The catechin component in green tea can also provide some biological effects. Some studies have proved that it would inhibit bacteria and eliminate viruses such as the flu virus, thus reducing the risks of infections. For example, drinking tea can reduce the attack of Streptococcus mutans, which is the main bacteria in your mouth and causes tooth decay or cavities. Thus, this drink is associated with improved oral health and a reduced risk of cavities. Additionally, green tea would help with your bad breath by killing odor-causing bacteria and restore fresh breath. [10]
