Raise a glass to this good news – drinking wine may help protect you from cavities and gum disease.
Sipping wine may be good for your colon and heart, possibly because of the beverage’s abundant and structurally diverse polyphenols.
Now researchers report that wine polyphenols might also be good for your oral health.
Antioxidants and polyphenols
Traditionally, some health benefits of polyphenols have been attributed to the fact that these compounds are antioxidants. However, recent work indicates polyphenols might also promote health by actively interacting with bacteria in the gut.
That makes sense because plants and fruits produce polyphenols to ward off infection by harmful bacteria and other pathogens.
Researchers wanted to know whether wine and grape polyphenols would also protect teeth and gums.
They checked out the effect of two red wine polyphenols, as well as commercially available grape seed and red wine extracts, on bacteria that stick to teeth and gums and cause dental plaque, cavities and periodontal disease.
Digestion of polyphenols begins in the mouth
Working with cells that model gum tissue, they found that the two wine polyphenols in isolation – were generally better than the total wine extracts at cutting back on the bacteria’s ability to stick to the cells.
When combined with the Streptococcus dentisani, which is believed to be an oral probiotic, the polyphenols were even better at fending off the pathogenic bacteria.
The researchers also showed that metabolites formed when digestion of the polyphenols begins in the mouth might be responsible for some of these effects.
