Iodine is an essential micronutrient that is critical for human health, particularly for the normal functioning of the thyroid gland. The thyroid gland produces hormones that regulate metabolism, growth, and development. Iodine is crucial for the synthesis of these thyroid hormones.
Iodine deficiency is a significant global health problem, affecting around two billion people worldwide, particularly in regions where soil lacks iodine. Insufficient iodine intake can lead to various health issues, including goiter (an enlarged thyroid gland), hypothyroidism (underactive thyroid), mental retardation, developmental delays, and impaired growth in children. In pregnant women, iodine deficiency can result in fetal brain damage, stillbirth, or miscarriage.
Nutrition experts emphasize the importance of consuming adequate iodine to prevent these adverse effects. They recommend the use of iodized salt, which is salt fortified with iodine, as a cost-effective and convenient method to ensure sufficient iodine intake. Additionally, nutrition experts educate the public about iodine-rich foods like seafood, dairy products, and eggs, as well as the potential risks of excessive iodine consumption, particularly in the form of supplements.
Overall, iodine matters to nutrition experts because it plays a crucial role in maintaining optimal thyroid function and preventing various health problems associated with iodine deficiency.
