The association between the Dietary Inflammatory Index (DII), the glycemic index (GI), and the glycemic load (GL) is not known, although it is known that carbohydrates are pro-inflammatory. We aimed to measure the association between the DII and both GI and GL among college students. In this cross-sectional study, 110 college students completed a 3-day food diary, which was used to calculate the DII, the GI, the GL, and the healthy eating index (HEI)-2010. Least square means and 95% confidence intervals of the GI, the GL, and the HEI-2010 were presented per DII tertile using generalized linear mixed models. Participants in tertile 1 of DII scores had lower GI and GL scores, but higher HEI-2010 scores than those in tertile 3. Pearson correlations showed that DII score was positively correlated with the GI score ( = 0.30, < 0.01), but negatively correlated with the HEI-2010 ( = -0.56, < 0.001). DII score was not correlated with GL score. Results from this study suggest that increased inflammatory potential of diet, as represented by higher DII scores, was associated with increased GI scores and lower quality of diet on the HEI-2010. Use of the DII suggests new directions for dietary approaches for preventing chronic diseases that moves beyond convention by decreasing systemic inflammation.
饮食炎症指数（DII）、血糖指数（GI）和血糖负荷（GL）之间的关联尚不清楚，尽管已知碳水化合物具有促炎作用。我们旨在测量大学生饮食炎症指数与 GI 和 GL 之间的关联。在这项横断面研究中，110 名大学生完成了为期 3 天的饮食日记，用于计算 DII、GI、GL 和健康饮食指数（HEI）-2010。使用广义线性混合模型，根据 DII 三分位数呈现 GI、GL 和 HEI-2010 的最小二乘均数和 95%置信区间。DII 评分三分位数 1 组的 GI 和 GL 评分较低，但 HEI-2010 评分较高。Pearson 相关性分析表明，DII 评分与 GI 评分呈正相关（ = 0.30， < 0.01），与 HEI-2010 呈负相关（ = -0.56， < 0.001）。DII 评分与 GL 评分无相关性。本研究结果表明，饮食炎症潜力的增加，表现为更高的 DII 评分，与 GI 评分的增加和 HEI-2010 上饮食质量的降低有关。DII 的使用为预防慢性病的饮食方法提供了新的方向，通过降低全身炎症，超越了传统方法。
