Personal update: I have, for all intents and purposes, finished the article on soy that I worked on for over 3 months. But, it is not yet live. I’m hoping it will be soon. In the meantime, I’m getting to the back log that built up during the time I was working on it.
And without further ado, here is some information on hair loss and iodine:
QuasiVegan’s post Hair Loss on the Vegan Diet, brought my attention to the fact that thyroid problems can cause hair loss, something that I was not aware of previously.
I have updated the VeganHealth.org article, Hair Loss, with the following:
Summary: Occasionally, women who become vegetarian or vegan report experiencing hair loss. If there is a dietary cause, the most likely are rapid weight loss, thyroid problems, or iron deficiency. Zinc deficiency and not getting enough of the amino acid lysine could also be culprits.
According to Mayo Clinic, an overactive or underactive thyroid gland can lead to hair loss. Upon going vegetarian or vegan, people might increase their soy intake. Soy can affect the thyroid, especially when iodine levels are not adequate or someone is predisposed to thyroid problems. Making sure you get enough iodine, by taking 75 to 150 µg per day from a supplement, should prevent any hair loss problems that could be due to iodine or soy. If you are predisposed to thyroid problems, limiting soy might also help.
