Iron deficiency in plants and humans: a common global challenge

Summary

Published in Trends in Plant Science in 2012, this review by Murgia et al. draws parallels between iron deficiency in crops and in human nutrition, framing both as manifestations of a shared global challenge. The paper likely synthesises current understanding of iron uptake mechanisms in plants and humans, highlighting how soil iron limitations constrain plant iron accumulation and thereby contribute to dietary iron deficiency affecting a substantial proportion of the global population. It is likely to discuss biofortification and agronomic approaches as dual-purpose solutions with relevance to both food production and public health.

UK applicability

While the paper takes a global perspective, its findings are applicable to the UK in the context of soil management, crop biofortification programmes, and dietary iron insufficiency in vulnerable population groups such as women of reproductive age. UK agricultural policy on soil health and nutrient stewardship may benefit from the integrated plant-human framework proposed.

Key measures

Iron bioavailability in soils and plant tissues; dietary iron intake and deficiency prevalence in human populations; biofortification strategies and their potential efficacy

Outcomes reported

The paper likely examines the parallel mechanisms of iron deficiency in plants and humans, exploring how low iron bioavailability in soils translates to inadequate dietary iron intake in human populations. It may also consider strategies such as biofortification and improved agronomic practices as interventions to address both problems simultaneously.
