Cause 10: Inadequate Iodine Supplementation
In many regions around the world, iodine supplementation has been implemented as a public health measure to prevent and combat iodine deficiency. The most common strategy is iodization of salt, which is considered one of the most cost-effective ways to supply the population with sufficient iodine. However, inadequate iodine supplementation can, paradoxically, be a cause of iodine deficiency.
This could occur for several reasons. For instance, not all salt available in the market is iodized. Consumers may unintentionally purchase non-iodized salt, or they may choose it due to taste preferences or misconceptions about the health effects of iodized salt. This could lead to inadequate iodine intake despite the availability of iodized salt in the market.
Even when iodized salt is used, the level of iodization may not be adequate to meet the individual’s iodine requirements. This can happen if the salt is poorly iodized or if the individual’s iodine needs are higher due to factors like pregnancy, breastfeeding, or certain health conditions.
Lastly, relying solely on iodized salt for iodine intake can be problematic if people are cutting down on salt intake for other health reasons, like managing hypertension. In such cases, individuals might not consume enough iodized salt to meet their iodine needs, leading to iodine deficiency. (10)
