Recent research suggests that short-term calorie restriction may help alleviate gum inflammation. This study, conducted by Dr. Giuseppe Mainas and Professor Luigi Nibali at the Dental Institute, King's College London, published its findings in the Journal of Clinical Periodontology.

What is a Fasting-Mimicking Diet?

A Fasting-Mimicking Diet (FMD) isn't about complete fasting but rather a way to control calorie intake in a manner similar to fasting. The researchers conducted a clinical trial involving 28 participants with moderate to severe periodontitis recruited from five hospitals in Spain.

Study Methodology and Procedure

Participants were divided into two groups: one followed the Fasting-Mimicking Diet, and the other maintained a regular diet. The FMD group consumed 1100 kcal per day for the first two days, then reduced it to 750 kcal per day for the subsequent three days. Starting from day six, they gradually increased calorie intake with soft foods, returning to their usual diet from day seven. This program was implemented three times over a six-month period.

Study Findings and the Link to Gum Inflammation

The results showed that the group adhering to the FMD had lower indicators of gum inflammation compared to the control group. Specifically, inflammatory markers in blood and periodontal tissues also decreased. Gum inflammation is a key indicator of the progression of periodontitis.

Oxidative Stress and Dietary Changes

The researchers attributed the benefits of fasting for patients with gum disease to reduced oxidative stress and changes in dietary habits. Oxidative stress occurs when the balance between free radicals and antioxidants in the body is disrupted, known to promote cell and DNA damage, as well as inflammatory responses. They also explained that reducing the intake of high-calorie foods like cakes and biscuits, along with refined carbohydrates, may have contributed to the reduced inflammation.

Professor Luigi Nibali emphasized, "There could be several reasons why fasting benefits patients with gum disease. Reduced oxidative stress and changes in dietary habits appear to have influenced the reduction in inflammation."

Finally, the research team noted that these findings suggest dietary modification could be a potential supplementary tool for managing periodontitis. However, it's important to remember that the study involved a small sample size of 28 participants, necessitating further research to confirm these effects.
