Wine News: Wine May Curb Cavities, Study Shows

Even with the alcohol removed, red wine and white wine may fight bacteria that cause cavities, an Italian study shows.
Before you toast the findings, remember that the study was done in test tubes. So it's too soon to count on a glass of wine to chase your cavities away.

The researchers, who work at Italy's University of Pavia, included Gabriella Gazzani, Ph.D.

First, they went to a local grocery store, where they bought some valpolicella (an Italian red wine) and pinot nero (an Italian white wine).

Back at their lab, the researchers stripped the alcohol out of the wine. They did that to prevent ethanol from interfering with their lab tests.

Next, the researchers marinated cavity-causing streptococcal bacteria in the wines. Both types of wine countered those bacteria and other streptococcal bacteria that cause some cases of throat infection.

Red wine might have had more antibacterial properties than white wine, but that wasn't certain, Gazzani's team notes.
