Post Vegetarian Diet; does soy cause a problem?

I have been on some thyroid sites and was shocked to see eating soy products discouraged. Does anyone have any information about this? Maybe this is the cause of my problem T3 results? Back to beans and rice? Any information would be appreciated.

All I know is that I've read over and over again that soy supresses the thyroid, so it's best to abstain from eating it in any shape or form.

I had been treated for hypothyroidism for ten years and only had minor hypo symptoms. In June I increased my soy product intake and my symptoms became severely worse. My GP increased my Synthroid but I still felt terrible. I went on an elimination diet, but I really thought my vitamins/supplements were the problem. Gradually I started to bring everything back and I began to slowly feel better. I was really confused as to the cause and then I read a similar post about soy products and I realized that the only thing I had not returned to was the soy products. I canít say with certainty that soy aggravated my thyroid problems, it could have been the low Synthroid dosage, but soy sure looks suspicious. Anyway, I have stopped all the soy products and continue to feel better.
I suggest stopping the soy products for two weeks, or a month and see how you feel. That will be tough on a vegetarian, but rice and beans arenít so bad.

I am not eating soy at all I have to rethink my diet. I thought even 1 & 1/2 tablespoons of Miso a day would cause a problem with thyroid meds? Am I over reacting?

No you are not over reacting. Soy is known to supress thyroid function. When I started eating it I noticed that my weight loss suddenly stopped and my periods became irregular (they were always regular up to then). When I stopped eating it my periods became regular again. I will never touch soy. Do a search on it and you will be surprised at what else it can do to your body. The Weston A. Price site has alot of info on soy, that might be a good place to start. Let us know what you think.

Well I have been not eating any soy for 2 1/2 weeks now and do feel so much better.I will go to the site and look at it. If I find some good information, I'll bring it to my Dr. when I go for my ecjeck. He said soy was OK.
