Following on from the post about magnesium, another study has confirmed that the malabsorption of selenium caused by gluten sensitivity contributes to many gluten sensitives developing thyroid problems (I have seen both hyper and hypo, much more commonly, in GSs). Selenium is always needed for the thyroid hormone production and conversion so will always be a factor somewhere if the thyroid is messing about.
The study concluded that “selenium malabsorption in CD (celiac disease) can be thought as a key factor directly leading to thyroid and intestinal damage” and that gluten does not just lead to gut damage but that other organs including the thyroid are at risk: “the target organs are not limited to the gut, but include thyroid, liver, skin and reproductive and nervous systems…”
They also note that selenium deficiency caused by gluten malabsorption is also implicated in autoimmune disease and excessive inflammation. These are the very factors I have been working on with the TGF prescription protocol, which is designed to lower the constant inflammatory process and balance the immune system amongst quite a few other things. I am patting myself on the back for that!

Read the blog post at the GlutenFreeSociety for more on selenium and this study.
In case it helps, here too are all the links to the tests he mentions for iodine loading, the thyroid screen including antibody levels (I found these only yesterday in a patient), thyroid reverse T3 and gene testing. I am still pleading with Spectracell to give us the nutrient test capability in the UK so not there with that one yet.
