Fight bad breath with a cup of green or black tea. Research suggests that the polyphenols in tea can reduce odor-causing bacteria.
Worried about bad breath? Sip on a cup of tea. Bad breath, or halitosis, occurs when oral bacteria produce foul-smelling sulfur compounds that stink up the mouth. Chemicals in green, black, oolong and white tea called polyphenols help prevent the bacteria responsible for bad breath and, at the same time, keep existing bacteria from making the offensive sulfur mixture. If you’re concerned about getting the most polyphenols per cup, white tea generally has the most, followed by green, oolong and black. However, studies on halitosis and tea show that black tea, which has the fewest polyphenols, is still effective in reducing bad breath. So drink whichever flavor suits you best.
