Nutritional iron deficiency (ID) is a widespread issue caused by insufficient dietary iron. Understanding iron absorption and losses is key to addressing this deficiency, especially in younger individuals.

Area of Science:

  • Nutritional Science
  • Human Physiology
  • Public Health

Background:

  • Nutritional iron deficiency (ID) results from inadequate dietary iron intake relative to physiological needs.
  • Previous research focused on iron absorption from whole diets, linking bioavailability, losses, and iron stores.
  • Recent studies offer new perspectives on regulating iron absorption and predicting changes in iron status.

Purpose of the Study:

  • To explore the regulation of iron absorption and its impact on iron stores and hemoglobin deficits.
  • To analyze the influence of age on the negative effects of iron deficiency.
  • To discuss challenges in assessing the prevalence of mild iron deficiency and potential underestimation.

Main Methods:

  • Review of studies on iron absorption, bioavailability, and iron losses.

  • Analysis of factors influencing iron stores and hemoglobin iron deficits.
  • Examination of diagnostic criteria for mild iron deficiency.

    • Main Results:

    • New insights into the regulation of iron absorption and the dynamics of iron stores.
    • Identification of age-related factors influencing the impact of iron deficiency.
    • Discussion on the underestimation of mild iron deficiency prevalence using multiple criteria.

    Conclusions:

    • Iron deficiency's effects are age-dependent, particularly up to age 20.
    • Current diagnostic methods may underestimate the prevalence of mild iron deficiency.
    • Sedentary lifestyles may contribute to the high prevalence of iron deficiency, obesity, and diabetes.
