Summary: Even minor iodine deficiency can have negative effects on thyroid health, while excess iodine intake can lead to thyroid disorders. Seaweed is a source of iodine that is gaining popularity as a food in Western countries. In addition to its role in thyroid health, gaseous iodine released from seaweeds plays a significant role in influencing coastal climate through cloud formation.

Summary: The study indicates that pregnant and postpartum women have mild-to-moderate iodine deficiency, and low iodine intake is associated with thyroid dysfunction. Initiating and continuing the use of iodine-containing supplements before pregnancy can help maintain better thyroid function.

Summary: Iodine is essential for thyroid hormone synthesis and plays a crucial role in infant development. The concentration of iodine in breast milk depends on maternal intake, and there are significant variations in iodine intake worldwide for lactating women, infants, and toddlers.

Summary: This study investigated the prevalence of iodine deficiency and associated factors in Canadian adults. Overall, the study found that Canadian adults have adequate iodine status, but there is a population with moderate to severe iodine deficiency. Factors such as iodine supplements, urinary volume, daily sodium excretion, and thyroxine use were found to be protective against iodine deficiency. Self-reported intake of dairy products was strongly associated with iodine status. Residents in Quebec City and Vancouver were more susceptible to iodine deficiency.

Summary: Despite some concerns, studies have shown that iodine supplementation does not have significant negative effects on thyroid autoimmunity or related dysfunction. Thus, promoting iodine supplementation in the general population is considered to be safe and beneficial.

Summary: Iodine deficiency disorder (IDDs) is a common health issue in mountainous communities, and using iodized salt is an effective control method. However, recent studies show that iodized salt is mostly lost during cooking. This study investigates the effects of organic and inorganic soil amendments on iodine uptake in coriander crops. Results indicate that applying an inorganic iodine source significantly enhances iodine uptake and that a suitable soil amendment can be an alternative to iodized salt in preventing IDDs.

Summary: The study found that iron deficiency, but not mild iodine deficiency, is a determinant of serum free thyroxine and total thyroxine levels in pregnant women. Correcting iron deficiency may help to maintain optimal thyroid function, in addition to preventing anemia during pregnancy.

Summary: This paper reviews recent studies on the re-emerging issue of iodine deficiency and declining intake among populations in developed countries. Iodine nutrition is becoming increasingly important within industrialized countries, but declining dietary patterns and food manufacturing practices have resulted in decreased iodine intake.

Summary: The article introduces a new method for the synthesis of iodine/beta-cyclodextrin complex and outlines the development of a new quantitative analysis method. Validation results of the high-performance liquid chromatography method demonstrate the reliability and accuracy of the method. The study found that the thyroid-stimulating activity of the iodine/beta-cyclodextrin complex is comparable to that of the conventional drug potassium iodide.

Summary: Pregnant women in Shanghai are at risk for iodine deficiency, which is associated with thyroid autoimmunity. The study found that consuming non-iodized salt and having inadequate iodine intake are individually associated with increased risk of thyroid autoimmunity.

Summary: This study evaluated the average dietary iodine intake and iodine status of a random sample of the Italian general adult population, finding that the iodine intake was lower than recommended levels despite the implementation of iodine prophylaxis strategy since 2005.

Summary: This study aims to investigate the effects of heat and light on the iodine content of packaged and open salt brands. The findings reveal that heat and light decrease the iodine content of salt samples. This study provides valuable insights into the stability of iodized salt against heat and light, and helps identify the optimal time to add salt while cooking and the appropriate storage conditions for salt in households.

Summary: This study aimed to assess the long-term effects of the transition in iodine status on the incidence of thyroid disorders. The findings showed that shifting to adequate iodine status significantly reduced the incidence of subclinical hyperthyroidism, positive thyroid antibodies, and goiter. However, it also resulted in an increased incidence of thyroid nodules.
