Italian researchers have found the same compounds that help give roasted coffee its aroma and flavor may also help fight cavities. After studying samples of ground and instant coffee, they found that the molecules in coffee help prevent cavity causing bacteria from sticking to tooth enamel.
The scientists looked at caffeinated and decaf, and determined that both have the same level of cavity fighting compounds. It's too early for any recommendations, but researchers say coffee may some day be known as the brew that helps battle decay, researchers say roasting is key, samples of unroasted beans didn't have near the cavity fighting power as roasted beans.
If you don't like coffee, try black tea. Studies in people show black and green teas also have the same ability to keep plaque away from teeth.
The study is published in the journal of Agricultural and Food Chemistry, a peer-reviewed publication of the American Chemical Society, the world's largest scientific society. The research was conducted at the University of Pavia and the University of Ancona in Italy.
