Hmm....well I guess you'd have to be pretty stable to see if you had a soy tolerance....HOWEVER, if your symptoms don't really change after you eat it, I'm sure it's fine.
I think that if you are not tolerant of it, you would know right away...
Lucky for me (SARCASM) my husband cannot eat soy...I started cooking with it and he had D every time. SO now I have to cook 2 meals all the time! It's wonderful....(more sarcasm)
