Red Wine Polyphenols may Help Fight Cavity-Causing Bacteria


Red wine polyphenols may help fight cavity-causing bacteria, suggests the test laboratory studies by researchers in Spain.



Red wine contains compounds that help in the fight against tooth decay and gum disease, according to a study published in the Journal of Agricultural and Food Chemistry.

Polyphenols naturally occur in plants and fruits. These compounds have health-promoting benefits such as lowering the risk of type 2 diabetes, reducing heart disease risk, and regulating body weight.

During the study, scientists looked into whether polyphenols, such as those in red wine, might also be good for oral health and oral microbiota. They compared effects of two polyphenols from grape seed’s and red wine extract supplements on bacteria that stick to teeth and gums and lead to cavities, gum disease, and dental plaque.

As a result, they found the polyphenols compounds and extracts reduced the ability of the bacteria to stick to the cells while the polyphenols – caffeic and p-coumaric acids were more effective.

“There is no good evidence that drinking wine per se is overall good for health – on the contrary, more and more evidence from other sources now suggests the less wine or alcohol one drinks, the lower the risks of range of disease and the lower the mortality risks,” said  the British Dental Association’s scientific adviser, Professor Damien Walmsley.

Polyphenols are also found in drinks like coffee, green tea, black tea, orange juice and lemon juice. Foods including apple, vitamin C foods, blueberries, kiwis, and cherries can help prevent tooth decay and gum diseases.
