Respectfully, that is incorrect for all but the poorest of diets. Iodized salt remains an important source of iodine for populations with limited access to diverse diets. The most common, and natural place people get iodine from is food. I outlined this in detail in the post you have not read. The standard RDA of iodine for those who are not pregnant is 150 mcg. - "An eight-ounce serving of nonfat cow’s milk contains 85 mcg of iodine, more than half of what you need daily." * Some brands even contain up to 168 mcg in one cup. - "A single hard-boiled egg provides about 26 mcg of iodine." So, just two eight-ounce glasses of milk give you more than your RDA of iodine—or just one eight-ounce glass of milk and three hard-boiled eggs. In addition: - "A three-ounce serving of baked cod contains 158 mcg of iodine, which meets your daily minimum." - "A 10 gram serving of dried nori seaweed (the type of seaweed used in sushi) contains up to 232 mcg of iodine, more than 1.5 times the daily required minimum." - "Because Greek yogurt is denser than milk, it has a higher concentration of iodine: up to 116 mcg per eight ounces." ...etc., etc., etc. All of this is outlined in the post with many other iodine-rich foods, and is readily available information on the web.
