Brazil’s iodized salt program builds on its success

(Eduardo Tomimori, Eduardo Nilson, Luiz Césio Caetano)
Brazil is the largest country in Latin America by both size and population, with over 200 million people. Iodized salt has been available in Brazil for more than 60 years and has eliminated IDD from most of the country: the Ministry of Health has promoted iodization of all salt for human consumption by establishing the legal, administrative, and operational conditions for USI. However, the IDD program faces new challenges, including possible mild iodine deficiency in pregnant women and harmonization with salt intake reduction efforts.

Thyroglobulin: a promising biomarker of iodine status

(Excerpted from Ma, ZF and Skeaff, SA)
Iodine deficiency is assessed by measuring urinary iodine concentration (UIC). But due to large intra- and inter-individual variation, UIC is only appropriate for groups. Thyroglobulin (Tg) is a thyroid storage protein and is a precursor for the synthesis of T3 and T4. In their paper, Ma and Skeaff reviewed the evidence on the usefulness of Tg to assess iodine status....

More iodine recommended for U.S. pregnant and lactating women

A policy statement developed by the American Academy of Pediatrics (AAP) appeared in the journal Pediatrics on May 26. It recommends iodine supplementation for breastfeeding mothers and recommends that young infants not be exposed to tobacco smoke or drinking water with excess nitrate. This is the first time that the AAP has issued a statement on iodine....

Why are iodine supplements recommended? A pediatrician’s view

(Stephanie Cajigal, Heather L. Brumberg)
Why do clinicians need to be aware of [iodine deficiency]?

We know that iodine deficiency in the United States is occurring at least marginally in about one third of pregnant women. Also, this deficiency may be compounded by environmental exposures that are ubiquitous: for example, perchlorate, which may take the place of iodide and thus make iodide less available for the thyroid and for breastmilk....

Salt iodization in Bangladesh: leaving no household behind

The Bangladesh Small and Cottage Industries Corporation (BSCIC), with the financial and technical support of GAIN, convened a day-long national workshop on 21 May 2014 in Dhaka, Bangladesh, on improving access to quality iodized salt for Bangladeshis...

Teaching students about iodine: an eye-catching article in ‘Science in School’

(Frithjof C Küpper, Martin C Feiters, Berit Olofsson, Tatsuo Kaiho, Shozo Yanagida et al.)
The discovery of iodine can be traced back to the 19th century and the Napoleonic wars. With the British imposing a blockade on European ports, the French were faced with shortages of saltpeter (KNO3) for manufacturing gunpowder. Chemist Bernard Courtois investigated the potential of seaweed (brown algae, Laminaria sp.) as the potassium source for this crucial substance...

Iodine biomarkers: a new interactive web interface

(Ramkripa Raghavan, Fabian Rohner, Daniel J Raiten)
The need for better data on the prevalence of health conditions and micronutrient deficiencies to guide intervention programs nationally and set priorities globally is well known. To address this need, the Biomarkers of Nutrition for Development (BOND) project was initiated in 2010 led by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD)/National Institutes of Health (NIH)...

IDD continues to threaten health and development in South Tajikistan

(Abridged from: Matthys et al.)
The independence of the Central Asian region from the Soviet Union in 1991 and the subsequent civil unrest in Tajikistan led to discontinuation of salt iodization programs in the country, resulting in an increase in IDD. The government designed legislation on salt iodization and launched the National Program for Elimination of IDD in 1997...

New Iodine Nutrition Survey Toolkit

A Survey Toolkit for Nutritional Assessment has been developed by the U.S. Centers for Disease Control and Prevention (CDC)’s International Micronutrient Malnutrition Prevention and Control Program (IMMPaCt) to provide epidemiological support to countries that want to assess and monitor the elimination of micronutrient malnutrition...

International standards: improving the quality of iodized salt supplies

(Frits van der Haar)
Since Universal Salt Iodization (USI) was first recommended as a key strategy for eliminating iodine deficiency in the 1990s, regulations on salt iodization have been enacted around the world. Salt iodization efforts straddle different interests across sectors of society, and effective follow-through of such regulations requires a collaborative partnership among public, private, and civic organizations, each with unique roles and responsibilities...

Bridging science and programs: iodine highlights from the 2014 Micronutrient Forum

The 3rd Micronutrient Forum Global Conference was held in Addis Ababa, Ethiopia on 2–6 June 2014 and marked the revival of the Micronutrient Forum. The theme of this year’s conference, “Bridging Discovery and Delivery” was driven
by the need to approach micronutrient malnutrition differently than in the past. ICCIDD Global Network (GN) had a strong presence at the Forum, taking the lead in several well-attended sessions....
