The study aimed to examine the association between a pro-inflammatory diet, estimated using the energy-adjusted dietary inflammatory index (E-DII), and the risk of periodontitis.
Association between inflammatory potential of diet and periodontitis disease risks: Results from a Korean population-based cohort study
Many study subjects from the population-wide Korean Genome and Epidemiology Study Health Examinee cohort were included for cross-sectional analysis and prospective analysis. DII and E-DII scores were calculated based on the intake reported on a validated semi-quantitative food frequency questionnaire.
The applied models revealed a significantly increased risk of incident periodontitis in individuals consuming high E-DII (more pro-inflammatory) diets in the total population and both men and women. The association remained significant even after excluding cases diagnosed early in the follow-up. In the cross-sectional analysis, a significant association was observed between the E-DII score and the prevalence of periodontitis among all study subjects and men; however, the association did not reach statistical significance in women.
Findings support the hypothesis that diets with high pro-inflammatory potential increase the risk of periodontitis. It is concluded that because of good chances and low risks, an anti-inflammatory diet can be recommended for the prevention of periodontitis.
