How much iodine is in iodized salt?
The Recommended Dietary Allowance (RDA) for iodine is 150 micrograms (µg) a day for adults. Iodine content varies widely in foods, as shown in the following examples: Food source Iodine content (in µg) Salt, iodized, 1 tsp. 400 Bread, made with iodized conditioner, 1 slice 142 Haddock, 3 oz. 104 – 145 Cottage cheese, ½ cup 26 – 71 Shrimp, 3 oz. 21 – 37 Cheddar cheese, 1 oz. 5 – 23 As a side note — lots of processed foods contain high levels of sodium. This sodium is not iodized, so don’t count on meeting your iodine needs through chips and other junk food! Hope this is helpful. If you’re looking to supplement iodine, kelp tabs contain approx. 225 mcg’s per taks. Buy them in a health food store and be sure your kelp comes from Iceland or Norway. Why? Because kelp absorbs radiation and you want to be sure the waters from which kelp comes, has not been contaminated.
