“…Another limitation is that only 27 of the 45 food parameters identified in the original literature search were available to calculate the E-DII in our study. We were also unable to validate the E-DII scores with inflammatory biomarkers in the AACES population; however, a recent study 18 validated the E-DII in an African American population by correlating the E-DII scores and CRP concentrations. The literature search for the DII has not been updated since 2010; however, with each literature update, the DII scores have remained relatively stable over time.…”

“…to reflect the literature on diet and inflammation through 2010. The improved DII has been validated by examining its relationship to inflammatory biomarkers ( e.g ., CRP and interleukin‐6) . Additionally, a more pro‐inflammatory diet, as defined by higher DII scores, has been linked to an increased risk of several cancers, including colorectal, pancreatic, prostate, breast and endometrial cancer .…”

Dietary inflammatory index and risk of epithelial ovarian cancer in African American women

et al. 2016

Chronic inflammation has been implicated in the development of epithelial ovarian cancer (EOC); yet, the contribution of inflammatory foods and nutrients to EOC risk has been understudied. We investigated the association between the dietary inflammatory index (DII), a novel literature-derived tool to assess the inflammatory potential of one’s diet, and EOC risk in African American (AA) women in the African American Cancer Epidemiology Study (AACES), the largest population-based case-control study of EOC in AA women to date. The energy-adjusted DII (E-DII) was computed per 1,000 kilocalories from dietary intake data collected through a food frequency questionnaire, which measured usual dietary intake in the year prior to diagnosis for cases or interview for controls. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were estimated using multivariable logistic regression for the association between the E-DII and EOC risk. 493 cases and 662 controls were included in the analyses. We observed a 10% increase in EOC risk per a one-unit change in the E-DII (OR=1.10, 95% CI=1.03–1.17). Similarly, women consuming the most pro-inflammatory diet had a statistically significant increased EOC risk in comparison to the most anti-inflammatory diet (ORQuartile4/Quartile1=1.72; 95% CI=1.18–2.51). We also observed effect modification by age (p<0.05), where a strong, significant association between the E-DII and EOC risk was observed among women older than 60 years, but no association was observed in women aged 60 years or younger. Our findings suggest that a more pro-inflammatory diet was associated with an increased EOC risk, especially among women older than 60 years.

“…Recently, the Dietary Inflammatory Index (DII) has been developed, a dietary tool which determines the inflammatory potential of an specific individual diet [9]. The DII has been originally validated with several inflammatory biomarkers by Shivappa et al [9], and later validated in different populations with inflammatory biomarkers [10][11][12]. Therefore, a high DII (i.e., a pro-inflammatory diet) may be associated with increased risk of suffering chronic diseases and/or all-cause mortality in humans [7,13].…”

Dietary Inflammatory Index and S-Klotho Plasma Levels in Middle-Aged Adults

2020

View full text Add to dashboard Cite

Background: Soluble Klotho (S-Klotho) is an aging suppressor with a close link with inflammation. However, it is still unknown whether the dietary inflammatory potential is associated with S-Klotho plasma level. We aimed to investigate the association of the Dietary Inflammatory Index (DII) with S-Klotho plasma levels in middle-aged sedentary adults. Methods: 73 middle-aged sedentary adults (40–65 years old) participated in the present study. DII was determined from 28 dietary items obtained by 24 h recalls and food frequency questionnaires. The S-Klotho plasma levels were measured using a solid-phase sandwich enzyme-linked immunosorbent assay. Results: a weak positive association was observed between DII and S-Klotho plasma levels (β = 52.223, R2 = 0.057, p = 0.043), which disappeared after controlling for body mass index (p = 0.057). Conclusions: A pro-inflammatory dietary pattern measured with the DII was slightly and positively associated with S-Klotho plasma levels in middle-aged sedentary adults.

“…The first construct validation, against hs-CRP, was conducted in the SEASONS study [32]. Subsequently, construct validations have examined the association between DII score and serum levels of hs-CRP, IL-6, and TNF-α in several populations [33][34][35][36]. In addition, multiple studies demonstrated the positive link between adherence to proinflammatory diet (the higher DII score) and levels of serum glucose, as well as, the association between the DII score and serum levels of lipid profile [37][38][39][40].…”

Background: The prevalence of diseases associated with chronic inflammation is higher in postmenopausal women. The dietary inflammatory index (DII®) was developed to evaluate the diet-associated inflammation. The aim of this study was to evaluate the association between the DII score and levels of fasting blood sugar (FBS), lipid profile, and inflammatory biomarkers.Methods: This cross-sectional study was conducted on 175 postmenopausal women referred to the southern health centers and health clinics affiliated to the southern municipality of Tehran, Iran. The DII score was calculated using dietary intakes derived from a validated food frequency questionnaire (FFQ). Concentrations of FBS, triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), high sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) were determined. Using linear regression models, we evaluated the association between the DII score and blood biomarkers. Results: After adjustment for covariates, the highest DII score category was associated with higher TG value (bDIIt3vs1= 0.08, p=0.03), TG/HDL-C ratio (bDIIt3vs1= 0.10, p=0.04), and IL-6 concentration (bDIIt3vs1= 0.06, p=0.01) compared to the first category of the DII score. Conclusions: We found a positive association between pro-inflammatory diet and unfavorable biomarkers in postmenopausal women.
