Raisins have a nasty habit of sticking on teeth. Because of their sugars and stickiness, people would normally think they are bad for dental health. But recent evidence suggests that this is not the case at all. It was discovered that raisins have no effect on the pH levels of the oral cavity and therefore don’t cause tooth erosion. Researchers also found that raisins do not stick on the teeth longer than other foods. Plus, they are natural cavity fighters!
How does it work?
According to the findings of Dr. Wong and his team of researchers, raisins contain antioxidants which inhibit the proliferation of Streptococcus Mutans, bacteria that is thought to be the main cause of dental cavities. An earlier study by Christine D. Wu, professor at the Chicago College of Dentistry of the University of Illinois, supports the bacteria-fighting effects of raisins. Wu says raisins contain phytochemicals which fight off bacteria that may cause dental cavities and gum disease. These dried and often sweetened treats contain oleanolic acid, a phytochemical that slows down or stops the growth of Streptococcus mutans, and Porphyromonas gingivalis, bacteria that is known to cause gum disease. Raisins also prevent these bacteria from sticking to teeth, which leads to the formation of plaques and cavities later on.
Recommendation: Snack on raisins after every meal or any time throughout the day to improve your dental health.
