“…That alone was giving the American population for decades a toxic overdose of iodine. Do we get iodine when we eat fresh fish as well? Yeah, having a serving of fish from the ocean once a week will pretty much guarantee our adequate iodine. And any seaweed kind of stuff too would give us plenty of iodine, right? Yeah, but you can overdose. A lot of people overdose by using iodine-rich seaweed. And what would the symptoms be of an overdose? I think it contributes to the high incidence of nearsightedness in the Japanese.”
