AllCharities interviewed our Chair, Prof. Michael Zimmermann, a global authority on iodine deficiency.

Prof. Eduardo A Pretell, MD, receives an award in recognition of his contribution to the elimination of IDD from the Americas and to mark 50 years of dedicated service to the ICCIDD (IGN) and the people of Peru and Latin America. Presented by Michael Zimmermann at the Micronutrient Forum on October 24, 2016 in Cancun, Mexico.

These maps show global progress made at the national level since the first global scorecard was published in 1993 to the most recent update in January 2015. The darker the colour, the more severe the iodine deficiency as a public health problem.

Inaugural session of the IGN's annual Management Council meeting, in Muscat, Oman. Speakers talk about global and regional (MENA) progress against IDD, and the role of the IGN in combining strategies for salt iodization with salt reduction.

Dr Basil Hetzel presented a Sansom Institute for Health Research Seminar on Wednesday 11 July 2012.

Salt iodization

"A simple, effective way to improve the health of the poor is to add iodine to the salt supply", says Nicholas D. Kristof in a video to accompany his New York Times article on salt iodizationAchtung Link öffnet sich in einem neuen Fenster, published in December 2008.

"An educated guess is that iodine deficiency results in a needless loss of more than 1 billion I.Q. points around the world", says Kristoff. "Probably no other technology ... offers as large an opportunity to improve lives ... at such low cost and in such a short time."

Iodine deficiency affects 2 billion people worldwide and is the leading preventable cause of intellectual and developmental disabilities. According to public health experts, iodization of salt, may be the world's simplest and most cost-effective measure available to improve health. Iodized salt is beneficial to the general public, however there is growing evidence that iodized salt may not provide a complete solution for pregnant and breast feeding women. Published on 30 October, 2015.

Consuming iodized salt helps to ensure adequate iodine nutrition among mothers-to-be, pregnant, and breastfeeding women. Optimal iodine status among women helps to ensure correct brain development in unborn babies.

Dibocor Salt is a small-scale salt harvester in the village of Farabougou in the Kaolack region of Senegal. Dibocor needs a new way to iodize his salt and the Micronutrient Initiative, harnessing the strength of its partners, may have the solution a sustainable solution for all of Senegal's small producers.

Video produced by Kenya's Ministry of Public Health and Sanitation. Children who consume iodized salt perform better at school, and this leads to higher achievements in life. Salt producers show support for salt iodization.

In Sudan, 22% of the population is affected by Iodine Deficiency Disorder, the single greatest preventable cause of mental retardation. This condition affects children's ability to learn. WFP is working with the Canadian foundation 'Micronutrient Initiative' to help address this issue. Salt producers in Sudan are being helped to improve their iodization capacity.

Micronutrient Initiative President Emeritus Venkatesh Mannar recounts his experience. This video was inspired by Venkatesh Mannar's interstitial discussion at the Scaling Up Nutrition side event during the 2012 UN General Assembly. The Micronutrient Initiative's work is undertaken with the support of the Government of Canada through the Canadian International Development Agency (CIDA) and other generous donors. Published on 30 Dec 2012.

Twenty years ago, Dr. Djokomoelyanto, a distinguished Indonesian endocrinologist injected large numbers of cretins in the surrounding area with iodine-infused oil. Kamidi was one of his patients. Within weeks, as Prof. Djokomoelyanto recounts in this moving Life programme, the cretins started feeling more energetic and lively.

Food fortification

Top executives, researchers and scientists in the field of nutrition answer the question, “What can the global development community do to ensure a #FutureFortified?” Among them is Jonathan Gorstein, the Executive Director of the Iodine Global Network.

We asked two of the world’s leading experts on nutrition and economics to document the benefits. Professor Susan Horton from University of Waterloo and professor John Hoddinott from Cornell have written a cost-benefit analysis of nutrition interventions aimed at reducing stunting; they conclude every dollar spent on nutrition in the first 1,000 days of a child’s life can give a saving of an average $45 and in some cases as much as $166. “The returns to investments in nutrition have high benefit cost ratios, and that this should be a top development priority.”

Representatives from government, the academe, civil society and the private sector converged on Arusha, Tanzania, for the #FutureFortified Global Summit, where they discussed ways to improve food fortification, an inexpensive way to introduce micronutrients in staples like rice, salt, milk, cereals and cooking oil. Devex associate editor Richard Jones delivers the highlights from Arusha, Tanzania.

Business Edition feature an interview with the Executive Director of GAIN, Marc van Ameringen and the Asst. Director of Nutrition Services from the MOH & Social Welfare and IGN Regional Coordinator for East Africa, Dr Vicent Assey as they talk about the #Future Fortified Global Summit held on 9-11 September in Arusha, Tanzania.

There are several key steps that can be taken to help elevate the profile of food fortification and help better address micronutrient deficiencies, Shawn Baker, the Gates Foundation’s director of nutrition, told Devex in an interview at the 2015 European Development Days. Published 26 June 2015.

Iodine supplementation

Every ten years the Swiss government distributes potassium iodide tablets to people living near nuclear plants, but how effective are they? In Switzerland there are four nuclear power plants currently generating electricity. Potassium iodide tablets are sent out by the Swiss National Emergency Operations Centre, as a precautionary measure in the event of a nuclear accident.

U.S. salt intake has shifted from table salt to processed foods. Gourmet salt, sea salt and salt in processed foods is not iodized. Because of this change, new iodine deficiencies may be showing up. This is important for pregnant moms, as iodine is essential to support the baby's brain development. Dr. Wendy Sue Swanson reviews new AAP recommendations for iodine supplements.

Global progress against IDD

An episode of Life Matters, with Amanda Smith on RN (Radio National) in Australia. Amanda interviews Creswell Eastman (Professor of Medicine Sydney Medical School, Principal at the Sydney Thyroid Clinic, Consultant Emeritus, Westmead Hospital) and Karen Charlton (Nutritional epidemiologist at the University of Wollongong's School of Medicine).

When Arnaud Laillou, a nutrition specialist with UNICEF, led a salt iodization study in 2014, he wanted to be sure that salt producers were not adding too much iodine.

Just four years earlier, UNICEF had stopped providing iodine to salt producers at the end of a decade-long, largely successful government-run iodization program. Laillou was stunned to find that 90 percent of coarse salt and 40-50 percent of fine salt was now not iodized. And all of it was labeled as iodized.

Endocrinologist Creswell Eastman does crucial work around the world, preventing birth defects caused by Iodine Deficiency Disorders. Professor Creswell (Cres) Eastman has led projects to abolish Iodine Deficiency Disorders (IDD) throughout the developing world.

Over the past decades, Cres and his teams have been effective in Malaysia, Laos, Thailand, Vietnam, Indonesia, China and Tibet. His transformative work with populations in remote areas of China led him to be dubbed "the man who saved a million brains".

Why does iodine deficiency still blight children in developing countries like India?

Justin Rowlatt travels to Dehradun in the Himalayas with world expert Chandrakant Pandav (IGN) to diagnose schoolchildren still suffering from goitre, and from the permanent mental retardation known as cretinism.

The iogeneration project intends to quantify iodine levels in school-aged children (6-12 years old) and to find a correlation between iodine levels and markers of cognitive development and thyroid health. This project also aims to explore the potential impact of iodized salt usage in meal preparation at school canteens and at home. In this study we collaborate with several schools form the North of Portugal with the involvement of Direção Geral da Educação (DGE).

In 2011 the UK became number 8 in the list of top iodine deficient countries in the world. Before the findings of this survey the UK was believed to be iodine sufficient. No significant improvement has been achieved since this finding in 2011. However recently there is a rapidly growing understanding of the importance of iodine for babies' IQ in the UK and worldwide too. Published on 30 October, 2015

NEW YORK, USA, 26 June 2008 - A new UNICEF report reveals that, over a period of almost two decades, enormous progress has been made in protecting children and mothers from the debilitating effects of iodine deficiency disorders (IDD). Thanks to a global campaign by UNICEF and its partners, about 70 per cent of households are now receiving iodine through iodized salt, and 34 countries have universal salt iodization.
