Final answer:
Kosher salt is less refined and has larger crystals, while iodized salt is fortified with iodine to support thyroid function.
Step-by-step explanation:
Kosher salt and iodized salt are two types of salt that have some key differences. Kosher salt is less refined than iodized salt and has larger, coarser crystals. It is often used in cooking and preparing kosher foods. On the other hand, iodized salt is table salt that has been fortified with iodine. Iodine is an essential nutrient that helps support thyroid function. It was added to salt to combat iodine deficiency, which can lead to developmental difficulties. The addition of iodine to salt has greatly improved health and development.
