A DGA-aligned pulse-protein diet may support iron homeostasis in older adults: an exploratory analysis of the PRODMED1 trial

Background/objectivesIron homeostasis is essential for healthy aging, yet whether Dietary Guidelines for Americans (DGA)–aligned diets support iron status in older adults remains unclear, particularly when iron is provided exclusively as non-heme iron. This exploratory secondary analysis of PRODMED1 examined iron-related outcomes, and nutrient-responsive signals involving methionine and FGF21 i...
