Tea Helps Prevent Bad Breath

Compounds found in tea can stop bad breath, according to researchers at the University of Illinois at Chicago. Also known as halitosis, bad breath is caused by foul-smelling sulfur compounds, such as hydrogen sulfide, produced by bacteria that thrive in environments such as the back of the tongue and deep gum pockets. Polyphenols, chemical components of tea, prevent both the growth of such bacteria and its production of the bad-smelling compounds, the researchers say.
