What this research studies

Our current guidelines for daily iron intake are based on older information from a less diverse population. This project will gather new information from a large group of US adults to see how much iron their bodies lose and how well they absorb iron from different foods. We will also look at other factors that might affect iron levels. The goal is to create more accurate and personalized iron recommendations for everyone.

Who could benefit from this research

Good fit: Ideal candidates are adults aged 21 and older who are already participating in the Nutrition for Precision Health (NPH) trial powered by the All of Us Research Program.

Not a fit: Patients not enrolled in the NPH trial or those outside the adult age range may not directly benefit from participation in this specific project.

Why it matters

Potential benefit: If successful, this work will lead to updated dietary iron guidelines that better reflect the needs of the diverse US population, helping more people maintain healthy iron levels.

How similar studies have performed: This project builds upon existing, but outdated, dietary iron recommendations and aims to provide new, more comprehensive data for a diverse population.
