I have Hashimoto hypothyroidism, I try to eat less soya products but soya hadn’t bothered me in the past. Yesterday at a dinner party, I had eggplant cooked in Soya sauce and had upset stomach. Has anyone experienced that? Chinese food usually has msg, sometimes I forget to ask no msg when I order Chinese.
Does MSG and soya sauce effect in Hashimoto hypothyroidism ?
Does it mean I am allergic to soya sauce?
Thanks
You could be allergic to soy sauce. Does it always affect you?
The reason soy is bad has nothing to do with having Hashi's. What soy does is stop thyroid hormone getting into the cells, thereby making you more hypo. It shouldn't upset your stomach - or if it does, that's nothing to do with the hypo.
MSG isn't really a problem. That was all a misunderstanding.
Greygoose , do goitrogenic foods like cruciferous veg have the same effect as soya?
To a certain extent in that they impede the uptake of iodine by the thyroid, meaning that it can make less hormone. BUT, you would have to eat one hell of a lot of them every single day for them to have any noticeable effect - more than normal people eat. And, if you're taking thyroid hormone replacement, it does concern you, because your thyroid doesn't have to make hormone.
But goitrogenic foods like cruciferous veg don't have the same effect at a cellular level, no. So, just forget goitrogens in general but avoid soy. 
Thanks Greygoose. I am careful to avoid soya but do eat broccoli, cauliflower, cabbage etc regularly as we are always told how good they are for us. I am also taking thyroid hormones so I guess that I will continue what Im doing.
Are you on gluten free diet?
Soy sauce has gluten in
No, dr doesn’t think I should!
Soy sauce, shoyu & tamari are fermented, so whatever is in non fermented soy is nullified. Tempeh is fine, too.
Unfortunately, not all soy sauce is fermented. Some of them are cheats!
If I eat any soy products I am doubled over in pain and vomit extensively, I have never been able to eat it! That goes for chickpeas, humus, couscous and any of the new age foods! I can eat normal meat and veg only.
They may be 'new age' to you, but other peoples have been eating them for thousands of years! 
Be that as it may, in the West these kinds of foods have only been served since travel became easy and unfortunately my stomach can’t deal with these foods! And while that may be amusing to you it’s agony to me!
No, it doesn't amuse me, actually. It's like people saying 'this foreign muck!' when presented with paella, but it's just rice and chicken cooked in a different way. Couscous is just semolina cooked in a different way - surely you've eaten semolina pudding? Chickpeas are just pulses. It's not like they've been created in a laboratory. Nothing 'new age' about them. If you don't like them, you don't like them, fair enough, but please be logical.
Soy is another matter entirely. It isn't even food. And, although it's been consumed in Japan and China for thousands of years, it was never intended as a main meal. It was taken as a condiment, not added to everything in vast quantities. No-one would have a plate of mustard for lunch, would they? But, because it's cheap, it's shoved into all sorts of processed foods, and I'm sure it's causing a lot of people to develop thyroid problems. Also, a lot of people are allergic to it. And, it's very bad for the environment! For all those reasons, I'm very anti-soy.
I haven't been able to make a direct connection to soy products and gastric upset, but definitely react to other proteins with (TMI alert!) bloating, gas, diarrhea, mucus in the stools, etc. I generally follow a gluten- and dairy-free diet or what Dr. Mark Hyman refers to as ”Pegan” AKA paleo vegan (I jokingly say I'm a vegan who eats meat & avoids gluten). A few months ago I read an article by Dr. Amy Myers and decided to try digestive enzymes and coconut charcoal--and that's been a game changer for me. I take the digestive enzymes with every protein-containing meal, and coconut charcoal to treat stomach/digestive upset. All I can say is FINALLY, I have a way to bring the troubling symptoms under control. An interesting question in the back of my mind is what else is so offending my system that I need these supplements every meal, and I wonder if it's animal proteins; which for me would be chicken, turkey, salmon & white fish as I already had to eliminate red meat, pork & shell fish by process of elimination.
I can’t eat processed soy. TVP gave me stomach cramps, & other processed forms of protein cause mouth ulcers in under 30 minutes. I try to avoid chemically processed foods altogether. I do miss tofu though tempeh is a tasty though expensive alternative.
Powdered garlic and onion in sauces sends my guts haywire. Maybe the sauce had them in?
I can’t eat undercooked or raw alliums, though fine if cooked thoroughly.
Maybe an allergy to nightshade vegetables?
I developed that a few years ago. I do ok with potatoes, but tomatoes, eggplant and green peppers give me a terrible stomach ache.
Could also be lectin in the eggplant. Read up about lectins, it is very interesting.
