Prep for whole body iodine scan

HI all, what kind of prep if any did you need to do before the scan? I see mixed info online and haven't gotten my instructions yet so I'm curious. Thanks!

There are some reasons for the mixed info; one is the evolution of research pointing to which foods are actually a problem for those doing WBS, and the other is the different selection of products using iodine in different regions. 

The best prep for you is the one studied by local researchers, where they test products available in your region. For instance, in my region there was one product of one specific brand of chocolate milk that had excess iodine, but only that one, not the whole brand, not all chocolate milk. 

There are some commonalities in preps all over the world like seafood, and this article will list most of them (www[.]healthline[.]com/nutrition/iodine-rich-foods), but that may vary. In my region milk and dairies do not have as much iodine as in the US, so they are not excluded from WBS prep here. 

What's is not done every time but I believe it should is to test urine iodine in the day(s) before doing WBS. This way the effectiveness of your prep can be assessed and the exam rescheduled if necessary.

None.

Aside from having a dedicated care provider (other than me) for a week for our young child.

In the US iodine content of food is not measured.

Even if the iodine content of food is not measured by manafacturers or authorities, independent research can still do it. That's how it was figured out that milk and dairies in the US carry large quantities of iodine...

Iodine content is highly variable and in the US it is impossible to know how much iodine a person is consuming.

Who knows if dairy cows continue to be fed iodine supplements or if iodophor sanitizing agents are still being used on dairy equipment in 2019.

Since iodine content is not consistently moniotored and is widely varied when it is; it's really a crap shoot to know how much iodine a person is consuming.

On a large country like the US or mine, sure; but locally(Los Angeles CA, Bose Idaho etc.), most food products come from a smaller selection of suppliers, whose iodine content can then be measured. 

And the target here is not a precise mg of iodine, just the ones carrying a lot of it.

But no one does measure it.  So it's moot.

Actually there was such program in the US, it was called BOND (Biomarkers Of Nutrition for Development), and the first nutrient they looked into was exactly iodine:
https://www.ncbi.nlm.nih.gov/pubmed/24966410

But this program doesn't exist anymore; USDA was supposed to carry such information, but any query on iodine at https://ndb.nal.usda.gov/ndb/nutrients comes empty. 

While in Spain, the local equivalent has iodine in food information:
http://www.bedca.net/bdpub/index_en.php

Over there prawn and milk contains the same 90ug/g of iodine, so people there know to avoid milk while dieting for it.

Other sites and studies are available in many other regions, but the US seem unwilling to do such. Too bad.
