Iodine Induced Reduction in Hepatic Deiodinase Activity Leads to Hypothyrodism and the Accumulation of Liver Fat That May Eventually Pave the Way to Diabesity

Image
While us Westerners think of goitre mostly as a result of iodine deficiency, the Chinese have learned by hard that the opposite is about as likely - goitre in response to iodine in the drinking water is a huge health problem in certain parts of the country (Zheng. 2000) As colorful as the web may have become, it is still full of paradigmatic black-and-white thinking: The world is either black or white and if you browse the blogosphere, it would appear that iodine would certainly belong to the white part of our world. That in exactly those people who are often referred to as an example of the multitude of beneficial health effects, namely the Japanese, a high intake of iodine has repeatedly been shown to be associated with low thyroid function and even full-blown hypothyroidism, on the other hand, is something you will probably not learn from the tons of unreferenced stuff you'll find on the Internet about how good, if not essential it was for your health to take copious amounts...

Green Tea & Your Thyroid: Are the T4 & T3 Reducing Effects of 250mg (HED) Green Tea Catechins Reason For Concern?

Image
Is there a devilish thyroid hormone eating dragon hiding out in your beloved green tea? There is hardly a day without great, yet mostly only promising, and rarely really relevant news about green tea. With it's anti-cancer, anti-diabetes, anti-everything-that-ails our society effects it bids fair to be the elixir of life. This life, and this is the result of a recently published study, SuppVersity reader Paolo had brought to my attention a couple of days ago, could however end up being one with slightly or even profoundly compromised thyroid function. Now, before you freak out because you have been drinking green tea for the past couple of years, do me a favor, mind the conditional in the previous sentence and read the rest of today's Easterly SuppVersity article, which is not an early April fool hoax. "You must be kiddin' green tea helps weight loss, so how can it reduce thyroid function?" It may sound hilarious that something that is touted as a fat bu...

Hypothyroid, Cold, Tired & Depressed? Try Replacing 50µg of T4 With 12.5µg of T3 - Study Shows, 65% of Patients Would not Want to Go Back to Synthyroid (T4), Only!

Image 1: Are you taking copious amounts of synthyroid (levothyroxin, T4), already, and feel as if your hypothyroidism became rather worse than better? Does Your Dr tell you that your TSH is fine and you should just exercise more and eat less to stop gaining weight like mad? Than this post is for you! The issue of optimal thyroid medication resurfaced as of late on the SuppVersity facebook wall , when I posted the link to a recently conducted retrospect study in patients who had undergone total thyroidectomy and were now receiving postoperative levothyroxin only hormone therapy by Ito et al. Not to my personal, but obviously to the researchers surprise, the textbook prescription of the "metabolically inactive"  T4 (essentially that is as almost 90% of "general knowledge about thyroid hormone metabolism incorrect as T4 can very well interact with thyroid receptors, it is though TR-alpha specific and has little metabolically activating effects, cf.  Koury. 2009) did ...

Rat Study Suggests Increased Selenium Requirements in Athletes

Calcium and magnesium , zinc and maybe chromium those are the top sellers among minerals and trace-minerals. Others, such as selenium are likely to be overlooked by the average fitness maniac, who says to him/herself "Selenium? Its in my multi, anyway!" Yet, a recent study published in Biological Trace Element Research ( Akil. 2010 ) reports well measurable effects of selenium supplementation to rats on an exhaustive exercise regimen. The scientists measured the impact of acute swimming exercise on erythrocyte-reduced glutathione ( GSH ), serum glutathione peroxidase ( GPx ) and superoxide dismutase ( SOD ), and plasma malondialdehyde ( MDA ) and lactate levels of the animals and found: Results of the study indicate that the increase in free radical production and lactate levels due to acute swimming exercise in rats might be offset by selenium supplementation . Selenium supplementation may be important in that it supports the an...
