The Mediterranean diet is known for lowering the risk of heart disease and supporting longevity. Now, new research suggests it could also benefit your gums.
A study from King’s College London found that people who ate more plant-based foods typical of the Mediterranean diet, such as beans, vegetables, fruits and olive oil, had healthier gums and less inflammation in the body. Those who ate more red meat and fewer plant foods were more likely to have gum disease and higher signs of inflammation.
The research shows that what you eat could influence oral health just as much as brushing and flossing.
“Our findings suggest that a balanced, Mediterranean-type diet could potentially reduce gum disease and systemic inflammation,” said first author Dr. Giuseppe Mainas, a postdoctoral researcher at King’s.
The study, published in the Journal of Periodontology, followed 200 hospital patients. Participants had dental exams, blood tests and filled out diet questionnaires, allowing researchers to see how eating habits connected to both oral and overall health.
Professor Luigi Nibali, who led the study, said the results add to a growing body of evidence that food choices ripple through every part of health.
“There is emerging evidence about the role that a balanced diet might have in maintaining a periodontal healthy status,” he said. “Our research shows the potential effect that a nutrient-dense, plant-rich diet could play in improving the nation’s gum health. Nevertheless, more investigation is needed to develop personalized approaches to help people manage their gum health.”
Though the study was small, it highlights a surprising link: the same eating style that protects your heart and brain may also keep your smile healthier.
The study was supported by the Faculty of Dental Surgery (Royal College of Surgeons of England) and the British Society of Periodontology. It was also made possible through King’s College London’s Dental, Oral and Craniofacial Biobank and research unit.
