Anti-inflammatory diet could reduce gingivitis

An anti-inflammatory diet could reduce gingivitis, according to a new study published in the Journal of Clinical Periodontology.  

Thirty patients were randomly assigned to one of two diets, experimental or control, stratified by their plaque values. For four weeks, the experimental group ate a diet low in processed carbohydrates and animal proteins, and high in omega-3 fatty acids, vitamin C, vitamin D, antioxidants, plant nitrates, and fiber. The control group did not change their diet.

Both groups suspended interdental cleaning during the study, and serological and subgingival plaque samples were taken at baseline and at the end, according to the abstract. Periodontal parameters were assessed by an independent dentist.

While researchers found no differences in plaque values, the experimental group showed a significant reduction in gingival bleeding, the study said. In addition, participants saw an increase in vitamin D and weight loss. The researchers found no differences in inflammatory serological parameters, serological omega fatty acids, or subgingival microbiome composition.

The plant-based, whole food, anti-inflammatory diet could significantly reduce gingivitis, said Johan Woelber, PhD, lead author lead author from the University of Freiburg in Germany.

"Study results clearly demonstrate the possibility to naturally reduce gingivitis by an optimized diet that also promotes general health,” he said. “According to this, dental teams should address dietary habits and give adequate recommendations in the treatment of gingivitis, since it might be a side effect of a pro-inflammatory western diet.”
