Unlock Healthy Gums: The Benefits of a Mediterranean Diet

Study Findings from King’s College London

Research conducted by King’s College London reveals that individuals who do not follow a Mediterranean-style diet are more likely to exhibit severe gum disease, particularly those with high red meat consumption.

In this cohort, researchers detected increased levels of circulating inflammatory markers, including Interleukin-6 (IL-6) and C-reactive protein (CRP).

Diet and Inflammation

Conversely, participants whose diets were rich in plant-based foods typical of the Mediterranean diet—such as legumes, vegetables, fruits, and olive oil—demonstrated lower levels of various inflammatory markers.

The research, published on September 15 in the Journal of Periodontology, assessed 200 hospital patients enrolled in the King’s College London Oral, Dental and Craniofacial Biobank. The study involved dental examinations, blood sample analysis, and dietary questionnaires.

Understanding the Mediterranean Diet

The Mediterranean diet emphasizes fruits, vegetables, whole grains, and healthy fats, and is associated with a reduced risk of major diseases, including cardiovascular issues, neurodegenerative disorders, and certain cancers.

Substantial evidence suggests that diet significantly influences human health by affecting the immune system and modulating inflammation, which is determined by the composition of dietary molecules such as macronutrients, micronutrients, and phytochemicals. Plant-based diets often contain higher levels of these beneficial molecules, contributing to lower inflammation.

Expert Insights

Dr. Giuseppe Mainas, the first author of the study and a postdoctoral researcher at King’s College London, stated: “Our findings suggest that a balanced Mediterranean-type diet could potentially reduce gum disease and systemic inflammation. We observed a possible connection between the severity of periodontal disease, diet, and inflammation. These considerations should be integrated when evaluating treatment strategies for periodontitis. Our research serves as a foundational step for further investigation into the relationship between dietary intake and gum disease.”

Professor Luigi Nibali, the lead author and a Professor of Periodontology at King’s College London, remarked: “Emerging evidence highlights the role that a balanced diet may play in maintaining periodontal health. Our findings illustrate the potential benefits of a nutrient-dense, plant-rich diet in enhancing the nation’s gum health. However, further research is necessary to develop personalized strategies for managing gum health.”
