Recognizing Differences in Ethnicities in Iron Status

A recent review shows that genetic influences on iron status differ among ethnic groups, with predominant research on Europeans. The applicability of these findings to other ethnicities is uncertain due to genetic variation. Using polygenic risk scores and direct measures of nutrient utilization could more accurately assess iron-related issues across populations. This understanding is crucial for evaluating iron supplementation policies and customizing iron intake guidelines for different groups.
