Which one is better, iodized salt or non-iodized salt, cannot be generalized, and the choice should be made according to the individual’s condition as well as the region. 1. Whether or not to eat iodized salt is related to whether or not an individual suffers from thyroid disease. If one suffers from hypothyroidism, it is generally recommended to consume iodized salt in moderation, while if one suffers from hyperthyroidism, iodine intake needs to be strictly controlled, and non-iodized salt should be chosen. 2. If the area is high in iodine, such as people living by the sea, it is recommended to choose non-iodized salt to avoid excessive intake. If the area is inland and iodine deficiency, it is recommended to use iodized salt as appropriate. Iodine is an essential element for the human body and is very important for the human body, so it should not be consumed too much or too little. Foods with high iodine content include seaweed, nori and other seafood.
