If a lot of salt now says “this salt does not supply iodide, a necessary nutrient,” where are we getting our iodide from?

Question

If salt is no longer a supplier of iodide, but there is no longer outbreaks of iodine deficiency like goitre, how are we all getting enough iodide in our diets?

Answer 1

Part of it will be the global supply chain. Deficiency to the point of physical abnormality was historically very localised to areas with soil nutrient deficiency. Nowadays it’s highly unlikely you are only buying local produce.

Now, consider that the problem is broader than just extreme cases. Reality is that iodine deficiency _is_ re-emerging. In Australia, Tasmania hits the news over it every few years. We might not be seeing goitres, but the problem persists at a level.
