Diet and Oral Health Connection
A new study has found that following the Mediterranean diet lowers the risk of gum disease, which in turn reduces inflammation tied to chronic illnesses and dementia. Experts highlight that gum health is closely connected to cardiovascular disease and systemic inflammation, both of which can increase the likelihood of conditions such as vascular dementia, diabetes, and fatty liver disease.
Role of Inflammation
Inflammation caused by periodontal disease can weaken blood vessels and damage major organs, including the brain. It can also disrupt the immune system and promote insulin resistance. Researchers emphasize that a predominantly plant-based diet like the Mediterranean model helps reduce inflammation and supports overall health. However, this must reflect the authentic plant-first approach, not a version heavy in red meat and cheese.
What the Mediterranean Diet Involves
The Mediterranean diet centers on fruits, vegetables, whole grains, legumes, seeds, nuts, and extra-virgin olive oil. Red meat is eaten sparingly, while fish rich in omega-3 fatty acids is encouraged. Poultry, dairy, and eggs are limited, and refined sugars are consumed only occasionally. Social aspects such as eating with family and friends, as well as exercise, are also integral parts of this lifestyle. The approach has been linked to lower risks of diabetes, dementia, depression, breast cancer, and cardiovascular disease.
Study Findings
Published in the Journal of Periodontology, the study assessed 200 UK participants through dental exams, blood tests, and dietary surveys. Results showed that low adherence to the Mediterranean diet and high red meat consumption were linked to severe gum disease and elevated inflammatory markers such as interleukin-6 and C-reactive protein. Conversely, higher consumption of vegetables, legumes, dairy, and olive oil correlated with reduced inflammation.
Practical Takeaways
Chewing vegetables, apples, and citrus fruits—key staples of the diet—promotes healthy gums by stimulating saliva and supporting beneficial bacteria. Experts recommend mindful eating and oral care as part of a holistic approach to reducing chronic disease risks. As one researcher noted, adopting this eating style benefits not just the teeth but the entire body.
