What does a corn intolerance or allergy look like? Are there "key" things? My oldest is finally willing to figure out if a particular food is the culprit to some GI stuff that she gets a bit. A complete elim diet would be very hard for her. . . long story. We were discussing possibilities. . .wheat, dairy, etc. But here is the thing: she is ok with triscuit crackers, but wheat thins send her to the bathroom. When we have them around, she would usually have cheese with them. Since she uses cheese on both, I don't think dairy. However, she has never liked milk and only likes a couple dairy items at all. I don't care if she eats dairy--we are moving away from animal products here. She also can't tolerate cheerios (dry). We compared the ingredients to cheerios and wheat thins and they both contain corn, whereas triscuits don't. It made us curious. I don't even know if this is food related. However, I have always thought she had some food issues, but blood tests as a young child always came back as negative.
