During a recent interview, a deputy director of scientific studies at a national center focused on food systems discussed iodine in iodized salt. The discussion highlighted that iodine in its common salt form is not always absorbed efficiently by the body and can fade over time. Several experts emphasized the need for stable iodine sources in nutrition and pointed to different chemical forms that dominate in salt products. [Citation: socialbites.ca]
According to the researcher, not all iodine compounds are equally stable. In some cases iodine compounds may degrade when exposed to light and heat, reducing their availability in food consumed by people. This insight underscores why simply relying on iodized salt may not provide consistent iodine levels in the diet. [Citation: socialbites.ca]
Another key point noted is that a common practice uses potassium iodate to iodize sodium chloride. While this method helps address iodine deficiency, it may not offer the best digestibility for every consumer. The practical takeaway is that the chemical form matters for absorption and effectiveness in real-world diets. [Citation: socialbites.ca]
Experts recommended exploring stable organic forms of iodine as better options. Organic iodine can be found in iodized proteins or in foods naturally rich in iodine, such as certain species of seaweed. When iodine appears in organic form, the body tends to absorb it more efficiently, supporting thyroid function and metabolic processes. [Citation: socialbites.ca]
In the food industry, iodized salt is not universally applied to every product. Some items may suffer from aftertastes or other sensory changes when iodine is added, so manufacturers weigh taste, texture, and shelf life in their decisions. Even so, iodized salt remains a cost effective strategy for reducing iodine deficiency on a population level. [Citation: socialbites.ca]
The expert also advised that dietary sources beyond salt are important. Consuming foods naturally containing iodine, like eggs and certain breads enriched with iodine, can enhance overall intake. These sources often provide iodine in a form that the body absorbs more readily compared with some fortified salt products. [Citation: socialbites.ca]
