iodinepoor
Iodinepoor is a term used to describe soils, diets, and populations that provide insufficient iodine to meet physiological needs. In agronomy, iodine-poor soils yield crops with low iodine content, reducing dietary iodine intake from plant foods. In human nutrition, iodine-poor diets can contribute to iodine deficiency disorders (IDD), which range from goiter and hypothyroidism to neurodevelopmental impairment in fetuses and young children.
Causes and geography: Soil iodine content varies; iodine is readily leached from soils by rainfall, especially
Health implications: IDD can be subclinical or present as goiter; deficiency during pregnancy increases risk of
Mitigation: Monitoring urinary iodine concentration, adopting iodized salt programs, iodine-enriched fertilizers, and targeted supplementation for pregnant
