Nutrition, evolution and thyroid hormone levels - a link to iodine deficiency disorders?

Abstract
An increased iodine requirement as a result of significant changes in human nutrition rather than a decreased environmental iodine supply is suggested to represent the main cause of the iodine deficiency disorders (IDD). The pathomechanism proposed is based on the fact that serum concentrations of thyroid hormones, especially of trijodothyronine (T3), are dependent on the amount of dietary carbohydrate. High-carbohydrate diets are associated with significantly higher serum T3 concentrations, compared with very low-carbohydrate diets. While our Paleolithic ancestors subsisted on a very low carbohydrate/high protein diet, the agricultural revolution about 10,000 years ago brought about a significant increase in dietary carbohydrate. These nutritional changes have increased T3 levels significantly. Higher T3 levels are associated with an enhanced T3 production and an increased iodine requirement. The higher iodine requirement exceeds the availability of iodine from environmental sources in many regions of the world, resulting in the development of IDD.

That's VERY interesting, really! Thank you for this article. Doctors, which I visit extremely rarely, always tell me that my blood T3 levels are "a little bit" too low. And I eat much more fish and seafood than most people here. Now I have the answer.
Grains and sugars are nothing more than a big disaster. I wish I knew this decades ago..

But a little bit too low according to what?
-
To the medical nazis standards..
Anyway certain amount of carbohydrates has to do some good for us we still have plain evidence that the liver converts proteins to glucose so if we have a quiet stable supply of nutritious carbohydrates like tubers(THE LIVER OF THE PLANTS) or some low fructose fruits we could take some stress of the liver because gluconeogenesis creates acidity and other byproducts?

I've seen a blogger and/or lecturer somewhere report that low T3 is normal for low carbers, but that most physicians and patients don't know this, so they tend freak out. I think it might have been Dr. Andreas Eenfeldt of Sweden.

It would be great to finally find out whether the whole input protein got converted at the rate of 58% or just excess of it. Different sources speak different things.

I had some kind of atypical diabetes where my blood sugars would raise after eating anything. I also had liver issues, it seems that my liver would produce sugar even while I slept. I would eat a small vegetable plate at night and by the time I would go to bed my blood sugar would usually drop down to 100, but then when I woke up in the morning it would jump to 115 even after fasting for 12 hours. During that period I had real bad liver and pancreatic pain and some type of systemic yeast overgrowth.
I believe my liver was damaged in a way that made it produce too much sugar, and it could be behind the reason I have taken so well to ZC, while many others have a bad experience with ZC transition.During my adaption my damaged liver kept making glucose, so I could more easily live without eating very many carbs. Eventually my sugars quit spiking and all the gut pain and yeast overgrowth disappeared, after about the first month on the diet.
I cant be the only one with this type of mutant physiology.

It sounds like you're one of the people who probably can do fine on ZC for a long time. When you hit 30 you might want to get your lipid profile blood work done every year, just to keep an eye on that. Also make sure you're drinking plenty of water, Lex Rooker got kidney stones b/c he wasn't having enough water every day on ZC. Otherwise, rock on.
