For a Picture-Perfect Smile, Eat Raisins.

Researchers at the American Society for Microbiology Annual Meeting in Atlanta, GA (June 7, 2005) found phytochemicals in raisins appear to fight cavities by inhibiting the growth of certain types of oral bacteria. Raisins also prevent the bacteria from sticking to teeth. Natural chemical compounds in raisins were shown to inhibit bacteria such as cavity-causing S. mutans as well as P. gingivalis, which promote periodontal disease.
