Why the study?
Diet and lifestyle modifications are essential in NAFLD management, prompting investigation into the association between diet-related inflammation and NAFLD.
Is diet-related inflammation associated with NAFLD in Iranian adults?
Population
3110 Iranian adults participating in the Amol Cohort Study
Comparison
Dietary inflammatory potential quantified by energy-adjusted dietary index (E-DII) score
Design
Cohort study using structural equation modeling
Key result
The energy-adjusted dietary inflammatory index showed no direct effect on NAFLD but was significantly associated with the disease through indirect mediation by hypertension, C-reactive protein, diabetes, and dyslipidemia.

Dietary inflammation is associated with NAFLD, with the effect mediated by hypertension, CRP, diabetes, and dyslipidemia, highlighting the importance of anti-inflammatory diets in metabolic disease management.
Doustmohammadian et al. (2024) conducted a cross-sectional in Nonalcoholic fatty liver disease (NAFLD) (n=3,110). Energy-adjusted dietary inflammatory index (E-DII) was evaluated on Direct association between E-DII and NAFLD (β 0.024, 95% CI 0.034-0.15, p=0.234). The energy-adjusted dietary inflammatory index showed no direct effect on NAFLD but was significantly associated with the disease through indirect mediation by hypertension, C-reactive protein, diabetes, and dyslipidemia.
