I recently purchased Gluten Free Penne (Barilla0 and one of the ingredients listed was mono and Diglycerides, within 1/2 hrs. I started to get all stuffed up, very bad allergic systems. Being that this product is gluten free, no msg, no soy, I could not figure out what was causing this allergic reaction. Was it the mono and Diglycerides??? It was bad and lasted a few days.
