I LOVE POPCORN but I was told NO gluten and NO grains! Grains really? YES! Corn is a grain! PS: Did you know that rice is a grain? Also, I purchased gluten-free, whole oats oatmeal... nope, oats are a grain!

Help! Is this true - No gluten and No grains for celiacs? I am currently receiving IVIG infusions and the infusion medication has corn sugar listed! Is this a Celiac concern?
