Joodipuudust

Joodipuudust refers to a deficiency in iodine, an essential mineral that the human body needs for producing thyroid hormones. These hormones play a critical role in regulating metabolism, growth, and development. Iodine is primarily obtained from food sources, with seafood and dairy products being common contributors in many diets. Soil iodine content significantly influences the iodine levels in locally grown crops and animal products.

The most visible consequence of severe joodipuudust is the development of a goiter, which is an enlargement of the thyroid gland in the neck. This occurs because the thyroid gland attempts to compensate for the lack of iodine by growing larger. In pregnant women, joodipuudust can lead to serious developmental problems for the fetus, including cretinism, a condition characterized by severe intellectual disability and stunted physical growth. Even milder iodine deficiency during pregnancy can impair cognitive development in children, potentially affecting their learning abilities.

Iodized salt is the most common and effective public health measure to prevent and treat joodipuudust worldwide. Fortifying salt with iodine ensures that a broad population consumes adequate amounts of the mineral. Other sources include certain seaweeds, fish, and dairy products. The recommended daily intake of iodine varies by age and life stage, with pregnant and breastfeeding women having higher requirements. Monitoring iodine status within populations is important to ensure widespread sufficiency and prevent the adverse health effects associated with deficiency.
