You see, every publication I have found regarding the low iodine diet disagrees on some points... usually several. In general, they agree on most things. I have found some almost disturbing discrepancies, however. For instance, every guideline I have seen so far says no soy products. Well, almost. According to Dr. Kenneth Ain, in The Low Iodine Cookbook (Norene Gilletz; Your Health Press, 2005)
Soy lecithin is extracted from soy oil, rather than the protein parts, and has just trace amounts of soy proteins (only enough to bother people with soy allergies). Soy oil, in reasonable amounts (usually as part of a vegetable oil mixture or a minor ingredient) won’t add any discernible iodine to the diet and is not goitrogenic. There is no reason to think that soy lecithin is in any way unsafe for the LID.Okay, good to know. SOME soy products are safe. Then I receive these guidelines from my doctor's office yesterday, and there is NO mention of soy at all. Not a single word of it.
Another point of confusion is with fruits. Yes, fruits. According to the ThyCa LID guidelines, there are no issues with fruits, aside from maraschino cherries and rhubarb. They make for wonderful snack foods and there are no problems with any fruits aside from the two mentioned. I have been going by this notion for the duration of my diet so far... only to find that this may be grossly wrong. The banana & strawberry smoothies I have been making for breakfast may in fact be quite high in iodine. The guidelines I received from my doctor yesterday states:
Allowed fruits and fruit juices: Apple (fresh only), apple juice, apricots (fresh only), avocado, berries, cherries (fresh only), cranberries, figs (fresh only), grapefruit, grape juice, grapes, mangos, lemon juice, melons, nectarines, oranges, orange juice, peaches (fresh only), pineapple (canned), pineapple juice, plums, tangerinesNow I have found, through my own research today, thanks to The World's Healthiest Foods Website, that strawberries are in fact one of the most iodine rich foods in the world. This source, at least, provides solid numbers. This I can work with. I'm tired of all of these lists of do's and don'ts with no numbers or resources to back them up. I need to start finding solid numbers.
Disallowed fruits: Bananas, dried fruit (raisins), applesauce, fresh pineapple, canned peaches or any fruit not listed in the foods allowed.
I could continue on and on with the discrepancies between the diets, but what's the point? Nobody really agrees. For my own sanity, however, I need a single definitive source. I need to know the iodine content of different foods. I need to know what foods I can and cannot eat while on this diet. I was astounded yesterday when I was reprimanded for drinking orange juice on the diet, by a lab technician who was assisting with my case! Not even doctor's staff knows the specifics of the diet! This should go to show just how contended the diet really is!
I think I have some work ahead of me...
