At a Washington, D.C. panel hosted by the Pan American Health Organization November 3rd, panelists representing the ICCIDD, US AID, Health Canada, PAHO, US FDA and the International Life Sciences Institute (ILSI) affirmed unanimously that there is no conflict between the global campaign to iodize salt and efforts in many countries to moderate salt intake levels.

Representing ICCIDD was Americas Regional Coordinator Eduardo Pretell, former minister of health from Peru. Pretell explained that as salt intake levels may vary, or as the iodine contribution of iodized salt changes within the overall diet, salt iodization programs have proved they can simply and easily adjust the level of iodine fortification. He emphasized the necessity of systematic monitoring of iodine sufficiency either through measuring the household use of iodized salt or, better, through regular population surveys of urinary iodine excretion.

Pretell also pointed out that there is no evidence that countries which iodize salt have different salt intakes from those that have inadequate iodization, nor has salt consumption changed when a country achieves salt iodization. He emphasized that special care must be taken to ensure adequate iodine intakes for pregnant and lactating women and educational efforts directed to these groups urging use of iodized salt as part of any population salt reduction effort.

He reminded the group that iodine deficiency is a perpetual threat for persons living in areas with iodine-deficient soils and that, for those areas, universal salt iodization is the consensus strategy to improve iodine nutrition because fortifying salt with iodine is the easiest and least expensive option.

Pretell’s comments were amplified by Dr. Omar Dary from US AID who spoke generally on micronutrient fortification, but chose virtually all his examples from salt iodization initiatives. Dary explained that salt is the ideal carrier for iodine and other vital nutrients because its intake is consistent and predictable. He warned that the U.S. is at risk of iodine deficiency, urged American food processors to use iodized salt and reiterated Dr. Pretell’s insistence that monitoring is the key to success in salt iodization.

The importance of Dr. Dary’s advocacy for food processors to use iodized salt was brought home by Dr. Eric Hentges, president of ILSI, who presented new data confirming that, in the U.S., about three-fourths of salt is consumed as part of processed foods (none of which is iodized).

The other speakers confined their remarks to advocacy of salt reduction, but all affirmed the importance of successful salt iodization.
