Sea salt lacks enough iodine to make a difference. Lots of processed foods contain so much sodium you don’t need table salt (which has iodine added). There are other foods that contain iodine. http://www.weightlossforall.com/foods-rich-iodine.htm
“Lots of processed foods contain so much sodium you don’t need table salt (which has iodine added).”
What is the source of the non-salt sodium in those foods?
