If you are eating a lot of soy, you might want to read up on how it promotes thyroid disease and problems in the stomach lining which may be contributing to your problems.
There’s an excellent book about this which not only goes into the health problems soy creates, but the way that the soy industry has lied and spun the research to convince a lot of innocent people that their beans are good for them, when they aren’t.
Soy beans have many qualities in common with peanuts it turns out, including the tendency to provoke allergic response. Details and a link to info about the book are at

BTW I used to eat a lot of soy too, but it ended up giving me a massive hormonal/depressive reaction which led me to researching “soy poisoning”. The problems resolved when I completely cut out soy, too.
