I like salt too Lise.
Salt shouldn't be used just to make things salty. If used properly in cooking, it actually draws the flavours of foods out making them more distinct and flavourful.
Although goiter is a thing of the past here, it is still common in other parts of the world, due to the lack of iodized salt. Before the early part of the 20th century, the most common cause of goiter was a shortage of iodine in the diet in areas where the soil was deficient in iodine. Without enough dietary iodine, your thyroid can't make and release enough of the two essential iodine-containing hormones.
Moderation.
