Does SOY effect THYROID?

Do you agree with that? I ve read a lot that it does, but my doctor (endocrinologist) says it doesn't. Who to belive?? Please help

I'd have to take into account where exactly you were reading that it does....but I'd most likely do more credible research in reliable medical journals to find out for sure.

probably in excessive amounts.

soy has a lot of phytoestrogens (fake-estrogens) so there's been a lot of hype about who should or shouldn't eat soy.

post-menopausal women and males shouldn't eat too much tofu.  

it just messes with the hormone balance, i guess. 

Thanks guys.. i have an intention to believe what i've read so far...they say people with hypothyroidism must avoid soy completely..., people with hypo function - do you eat soy?

 Actually I heard from an RN that post-menopausal women SHOULD eat soy because it helps their body regulate itself. It can lessen the effects of menopause.

I eat soy constantly. Soy milk with soy nut butter at breakfast, soy crisps for lunch, soy cheese sandwich, more soy milk, soy ice cream. I can't get enough. It honestly depends on the person because I have heard people who love it (like me) and other people who say it makes them feel bloated. 

wait sorry lol, but if soy does effect your thyroid, is it in a good way or a bad way? like speeds it up or slows it down?

mmmmm soy cheese :) i just had some, i love it because it tastes like nothing... which is awesome since real cheese tastes and smells like vomit :P

in large quantities, it may have some (negative) effect on hypothyroidism.  my advice (and my endocrinologist from several years back agrees) is that if soy is a large part of your diet, keep eating it, just monitor your thyroid levels + make adjustments in your replacement hormones as necessary (soy is one of my major protein sources; i eat it just about every day, and have never had a problem).  it's probably most likely to have an effect if you haven't eaten soy up till now, or are greatly increasing the amount you eat.  like with everything, the key is monitoring.
