To make a long story short, I had thyroid surgery at the end of November. Next Wednesday, for follow-up, I need to take a dose of Iodine-131. In preparation for that I need to cut iodine out of my diet for a week -- the basic idea being that if I deprive my cells of iodine they will more readily suck up the I-131. That's all I'll say about the medical aspects of this, however from a culinary standpoint there is much to discuss.
When I was thinking in the abstract about a diet without iodine, I figured how hard could it be? I mean, it's not like I crave iodine, sprinkle it on my food or even have any around. But then I started reading the booklet my endocrinologist gave me.
The first thing you have to avoid is iodized salt. This sounds simple, and when it comes to home cooking it is: you can just use non-iodized salt. But everything prepared in a restaurant, commercially, or in anybody else's home is suspect. Basically, for the week I can't eat any restaurant food, any packaged food, or any food anybody else cooks unless it is supervised by me with great rigor.
The salt issue is compounded by a ban on sea salt -- anything from the sea is banned. That does still leave non-iodized kosher salt, though. I guess all salt, even rock salt in mines, ultimately traces back to the sea, but after checking with multiple authorities I learned that my bottle of David's kosher salt is okay for the diet.
The salt restriction also applies to salt variants like garlic salt and onion salt -- not that I care.
Then you're not allowed to eat any milk products. I don't know why this is exactly, and some sources have led me to question the restriction, but I'm not going to start being a difficult patient about it when it's just for a week.
And no fish, at least not fish (or seafood) from the sea. Freshwater fish are theoretically allowed but it's not like I'm going to seek out any fish.
The ingredients iodates, iodides, algin, alginates, carrageen, agar, and kelp are forbidden.
The iodate restriction rules out all commercial bread products. It may be that some are made without iodate but it's a blanket restriction because there's no way to know.
No eggs.
No vitamin or dietary supplements.
Nothing with red, orange or brown dye.
No iodine on cuts.
No soy products.
No canned foods.
That's the short version of the list. If you unpack each item you get much more detail. So for example the brochure I have elaborates on the commercial-bread restriction thus: "Avoid: All commercial breads and rolls, processed boxed cereals, salted crackers, potato chips, pretzels, bagels, bialys, Melba toast, all other crackers, egg noodles, packaged rice and pasta mixes."
It goes on like this about everything.
Now, a sane person would probably just avoid bread for the week. But I decided to bake. Heckers says there's no iodate in their flour, David's says the kosher salt is neither from the sea nor iodized, Red Star yeast is approved, as is tap water. I decided to give the Jim Lahey/Mark Bittman no-knead recipe a try. My son and I made the dough last night and will bake this afternoon after school.

Last night we had a farewell-to-iodine supper at Dinosaur Bar-B-Que in Harlem. I made the joke, "This iodine is so great!" a few times too many. The group ordered me to stop. I even tried a little salmon, because I could.
So, join me this week for a chronicle of the low-iodine diet. If you happen to be on a low-iodine diet, or have expertise in this area, or even if you don't, I'd love to hear your ideas.
