SeaSiren Posted July 17, 2006 Share Posted July 17, 2006 I have been hypo-thyroid for over a decade now and on Synthroid. I learned today that soy can interfere with Synthroid and went directly the makers website, and low and behold. It is in their literature. Since becoming vegan (a few years now) I have not been able to get my thyroid symptoms under control. They actually had to up my dose for the first time in my life (about 6 mo ago). The doc knowing I am vegan which is why I no longer have high BP or high cholestrol could have at some point mentioned this. I think it could have been a bit helpful. Since doing research on it I have found everything from no soy to no soy within 4 hours. Apparently they are still studying the effects since most infants on soy formulas don't have hypo-thyroid and adults consuming lots of soy products is fairly new. Unfortuantely in Asian countries where a lot soy is consumed, most go undiagnosed, so there isn't enough info. Anyway it looks like I'm going no soy for a month to see what happens. Now I need to redo my eating habits. I'll keep you posted. If anyone has any more information on it, I would appreciate it. Link to comment Share on other sites More sharing options...
plc3 Posted July 17, 2006 Share Posted July 17, 2006 Hi SeaSiren, About 5 years ago, I was diagnosed with multinodular goiter, a different thyroid problem. About the same time I was experiencing the symptoms of an under active thyroid. However, my bloodwork is normal. I see my PCP about once per year to have my thyroid and bloodwork checked. My PCP believed that I will eventually need synthetic hormone. I am hoping with diet I will be able to avoid having to take any meds. When I was diagnosed with goiter, I started looking around on the internet to find out what could have caused it, and I learned that soy does affect thyroid function. So I tried to avoid it as much as possible. I also learned about goitrogens (foods that can supressthyroid functon and cause goiter- brussel sprouts, kale, broccolli,etc), and tried my best to avoid those as well. Since I have gone raw, the soy isn't a problem, but I have been eating a lot of kale and cauliflower. Anyway, here is a link that I had bookmarked about food, medication, and suppliments and how they affect your thyroid. http://thyroid.about.com/gi/dynamic/offsite.htm?zi=1/XJ&sdn=thyroid&zu=http%3A%2F%2Fwww.thyroid-info.com%2Farticles%2Fthyroid-drug-faq.htm And here is one that talks about goitrogens (and lists soy as one):http://www.ithyroid.com/goitrogens.htm Good luck with getting your med. dose correct Link to comment Share on other sites More sharing options...
Rain Forrest Posted July 18, 2006 Share Posted July 18, 2006 Hey, have you tried getting iodine from sea-weed? I think iodine could be potentially lacking in the vegan diet, and it is important for thyroid health. Since I started snacking on sea-weed I feel really great!
