Description
Qi He, Qianying Guang, Yien Xu, and Jian Zhao mined United States survey data from 2003 to 2014 for a 2026 study on diet variety and gum disease. Eating a wider mix of foods might calm the inflammation behind periodontitis, but the link was unproven.
After full adjustment, each step up in dietary diversity score came with lower odds of gum disease, at an odds ratio of 0.95 in the adjusted model, with a smooth dose pattern and no curve. Five food groups shared the credit almost evenly, hinting at synergy rather than one hero food. Body roundness and a red cell spread measure carried small parts of the effect. Widening the weekly menu, they argue, is a simple prevention lever.
