Short-term fasting may reduce inflammation linked to gum disease

A study by King’s College London found that short-term low-calorie diets may reduce inflammation markers linked to gum disease. Published in the Journal of Clinical Periodontology (JCP), the research suggests that lifestyle modifications could support traditional plaque control and professional cleaning in managing periodontitis.

How did the low-calorie diet affect gum inflammation?

Patients who followed a restrictive diet showed reduced markers of inflammation in both blood and gum tissue compared to a control group. This included lower levels of C-reactive protein, which is a general indicator of inflammation throughout the body. Researchers also found reduced molecules specifically linked to inflammation in the gums.

The study tracked 28 patients across hospitals in Spain. One group continued their usual diet, while the other followed a specific fasting cycle three times over six months. These patients ate 1,100 calories for two days, followed by 750 calories for three days. On the sixth day, they introduced soft foods before returning to a normal diet on the seventh day.

To measure results, researchers analyzed blood and gingival crevicular fluid. This fluid exists in the small space between the tooth and gum to help fight germs and maintain health.

Why does fasting help patients with periodontitis?

Prof. Luigi Nibali, a senior author of the study, stated that fasting reduces oxidative stress in the body. This stress is a common cause of inflammation that can damage DNA and cells. Restricting high-caloric foods and refined carbohydrates, such as biscuits and cakes, further reduces this oxidative stress.

Nibali also noted that fasting may have beneficial effects on the microbiome, the community of bacteria that helps keep the body healthy. However, he clarified that more research is required to confirm this specific relationship.

Dr. Giuseppe Mainas, the study’s first author, noted that lifestyle modifications could be important alongside proper tooth brushing. This is significant because periodontitis affects millions worldwide and is linked to systemic issues like diabetes and heart disease.

What happens next for gum disease treatment?

Researchers may investigate fasting-mimicking diets as supporting therapies alongside professional cleaning and oral hygiene support. Dr. Mainas indicated that a larger study is a likely next step before these methods are potentially incorporated into standard gum disease treatment.

The application of these diets may not be universal. Dr. Mainas warned that restricting foods could be dangerous for certain patient groups, such as those with diabetes. Consequently, future dietary advice would need to be targeted to specific groups. Researchers are currently investigating how to provide these benefits to high-risk patients who may be unable to fast.
