This is a hidden form of MSG in food that does not have to be put on the label. Many meat substitutes are made with soy protein isolate.
He used to eat a good amount of soy when we were all vegan. Since we started eating animal products (about a year ago), he has been eating minimal (if any) soy. When he was much younger, we tried eliminating soy, corn, gluten, and dairy all at once (while he was also vegan). I can't say I saw any improvement in his symptoms, but I suppose it couldn't hurt to try again. He really loves food, especially trying new things, so it's hard to consider restricting his diet further -- he's really sensitive about that. It's also confusing because he often has a few good days in a row, when there haven't been any dietary changes or anything. So I feel like there's something else affecting him but I have no clue what it could be. I am noticing that as much as he loves
being out & about, staying home more seems to be improving his behavior and moods.
