I love salted kelp from the store. It is like eating potato chips, but far more healthy.
It is loaded with minerals & does contain some needed iodine. We also love seaweed soup.
Unfortunately there is not enough Iodine in seafoods to detox our body from the toxins of Fluoride, Bromide & chlorine. See this for how these toxins take over every cell in our body to make us sickly and ruin our immune system. http://tinyurl.com/iodine-and-halogen-robbers
In order to properly detox, Dr. Brownstein recommend his Iodine protocol for at least a year. Then after all the toxins have been driven out, and our cells are once again filled with iodine, we can drop down to a maintenance level of Iodine for good health. Eating a lot of seafoods or 12.5 mg of iodine daily may be sufficient if we can avoid foods & drinks loaded with bromide, fluoride & chlorine.
