There are recent studies that say blueberries help fight gum disease (periodontal disease). The Centers for Disease Control and Prevention (CDC) have found that nearly half of American adults over 30 have some form of periodontal (gum) disease.
Periodontal disease can lead to infections that need to have antibiotics. The blueberry extract has been found to have antibacterial and anti-inflammatory properties.
Another benefit of blueberries, who knew?
