I watched a documentary some years ago regarding the poor in Nepal being placed at rrisk of serious health problems as they could not afford sea salt and only consumed rock salt which did not have any iodine.
A person only needs around a single teaspoon of iodine in their lifetime but without it, especially whilst growing up, serious problems occur.
Hilmalayan pink rock salt comtains very little iodine.
“Although pink Himalayan salt may naturally contain some iodine, it most likely contains less iodine than iodized salt. Therefore, those who have iodine deficiency or are at risk of deficiency may need to source iodine elsewhere if using pink salt instead of table salt.”
