I find this story about iodine insufficiency causing problems and how adding just a teensy bit to the water supply in poorer countries would raise the IQ up a few points. (also here if you prefer that whole paper-of-record thing)
butting heads with this post on my favorite blog after this one:
I don’t think most people really appreciate how important good salt and good pepper are for cooking. I watch people go through all sorts of elaborate rituals with their cooking, using expensive ingredients and arcane procedures to cook their “gourmet” meal, and then I watch them use Morton’s table salt and/or McCormick’s pure ground pepper (which is really only good for sneezing) and wonder what the hell they are thinking.
Me and my husband HP use kosher salt for cooking. It's easier to work with and all the chefs on foodnetwork.com always say to use it. Over and over again. It goes without saying what I think of pre-ground pepper. I won't let that drek in the kitchen.
But I sometimes wonder about where I'm supposed to get my iodine, since I'm not getting it in my salt. And now I know why I keep forgetting to do something about it – I'm 'effing retarded from iodine insufficiency, that's why.
