I can't tell you how challenging it was to add corn products back into my diet WITHOUT adding in soy, gluten, or dairy....aside for straight up corn (on or off the cob). I know from past experience that my body does not digest raw or cooked corn well. I didn't think I had an issue with popcorn. Ummm, I think I was wrong. On day one of my corn test, I had corn tortillas, which I toasted, broke into pieces and ate with salsa for an afternoon snack. YUM! I also had some air popped popcorn drizzled with coconut oil as an evening snack....BIG MISTAKE. At the risk of TMI, the popcorn went right through me. I had awful stomach cramping and gurgling. It was so bad that on day 2, I limited myself to only the corn tortillas with salsa, and a tsp of cornstarch straight up (I know, not a fun way to eat it, but I couldn't figure out another way to test cornstarch, without my other allergens sneaking in). My tummy was still rumbly, but much better than the day before. I was completely back to normal on day 3, when I did not add in and corn products.
What does this mean from now on? Well, I really need to limit my corn intake. Once I get past the rest of my allergy elimination, I will test processed corn within products. I am pretty sure cornstarch is OK for my system (especially in baked goods), but I won't know for sure until I try adding it back in as part of a product.
