In answer to your question, three months ago I could NOT pass up two bites of a Belgian Lacy Cookie with a roasted marshmellow. It was to die for, literally. I've forgotten the digestive distress it caused, but I remember the rash I had for a month. It was so painful. I hadn't remembered it being so painful before. When I'm tempted, I remember that rash. I'm starting to have food aversions. I've actually asked my coworkers to support me in periods of weakness. They say: "Don't eat it, it will make you sick."
I'm grain free, and avoid "gluten free" labels. It's tough, but I've learned a lot about what makes me sick. Prepared and proceesed foods aren't reliable. I challenge you to eat grain free and proceesed free, all prepared at home meals for two weeks, and see how you feel. You can still eat fresh meats and fish, up the greens, sweet potatoes and squash and the olive oil or butter from grass feed cows. Then you'll will see what gluten does to you when you cheat. That little headache that you haven't had suddenly comes back. You mysteriously get another sinus infection, and the list goes one. Don't torture yourself. Your tastes will change, and you will take others with you on a health food journey when they see how amazing your skin looks because of all the beta carotene your getting in your diet.
