Abstract only (the AJCN supplement full text could not be retrieved): iron bioavailability is estimated at 14-18% for mixed diets and 5-12% for vegetarian diets in subjects with no iron stores, the values used to set dietary reference values. Phytate, polyphenols, calcium, ascorbic acid and muscle tissue shift absorption strongly in single-meal isotope studies but only modestly in multimeal studies with a varied diet; the nature of the meat factor is unresolved; iron status generally has a greater effect than diet composition. The abstract gives no separate heme vs non-heme absorption percentages (abstract, PMID 20200263).
