I'm curious to know how people dealt with goiters in the days before iodine was added to salt. I imagine that quite a few people had colloid goiter, unless there was plenty of iodine in the soil that their food was grown in. I wonder when they figured out the connection between goiters and the lack of enough iodine?
I'm also curious about how and when they started treating this disorder and what the treatment was? Anyone have any answers? Thanks.
