Associations between dietary iron intake from different sources and the risk of hyperuricemia among US adults: a cross-sectional

Background: Currently available evidence on the association between dietary iron intake and hyperuricemia is limited and inconsistent. Objective: This study aimed to examine the relationships between animal-derived dietary iron (ADDI) in- take, plant-derived dietary iron (PDDI) intake, and the ratio PDDI:ADDI and hyperuricemia risk among US adults.
