Summary
This review article, published in the journal Nutrients, provides a comprehensive synthesis of the evidence on dietary iron bioavailability, covering the physiological and dietary determinants that govern iron absorption in humans. Gibson and colleagues examine how food composition, meal patterns, and host factors such as iron status interact to influence the efficiency of iron uptake. The paper is likely intended as a reference resource for researchers and practitioners working on iron deficiency and dietary adequacy across diverse populations.
UK applicability
Although the review is international in scope, its findings are directly applicable to UK dietary guidance and public health practice, particularly in the context of iron deficiency anaemia, which remains a concern among UK women of reproductive age and certain dietary groups such as vegetarians and vegans.
Key measures
Iron absorption (%; fractional and total); dietary iron bioavailability modifiers (phytate, ascorbic acid, polyphenols); haem vs non-haem iron content of foods
Outcomes reported
The paper examines the bioavailability of dietary iron, reviewing the host, dietary, and food-processing factors that enhance or inhibit iron absorption. It likely reports on the relative contributions of haem and non-haem iron sources and the influence of dietary constituents such as phytate, ascorbic acid, and polyphenols on iron uptake.
