Yes, I have Graves disease myself and have been warned away from any soy products. I used them at one time for hot flashes and I also like edamame and crunchy soybeans, but understand it to be a no no I eat them sometimes anyway but recently my thyroid dose is screwed up again. I guess for that reason alone I should probably stay away from the products for the most part. Four out of five in my immediare family have thyroid disease.

A favorite site I use is Mary Shomon's http://thyroid.about.com/
