I recently discovered that I am gluten intolerant. I eat a lot of popcorn for my snacks. I pop my own corn the old fashioned way using Orville Redenbacher's popping oil. Everytime I eat it I get diarrhea the next day. What is in Orville's popping oil that would trigger diarrhea in me? What all is in his "flavorings"? Or what else could it be?
