Celery is good at fighting bad breath because it’s full of fiber. Fiber-rich foods help produce saliva, which helps to wash away plaque build-up, a cause of halitosis. Carrots and apples are other good, fiber-rich snack options.
Vitamin C can help prevent gum disease and gingivitis – major causes of bad breath. By eating foods rich in vitamin C, you also create an inhospitable environment for bacteria growth. Chow down on citrus fruits like oranges, or grab some berries and melons to get your daily dose of vitamin C.
Black tea helps keep your breath smelling sweet because it is full of polyphenols, powerful antioxidants that stop plaque from clinging to your teeth. Plaque build-up leads to bad breath, among another dental problems. Studies have also found polyphenols inhibit the growth of bacteria in the mouth, thus minimizing the foul-smelling compounds that those bacteria produce.
