Best Leaky Gut Healing Diet To Follow in Food Intolerance & Leaky Gut Posted December 9, 2012 · Report to Admin I'm glad the SCD diet worked for you. But please, there is NO CURE for celiac disease. If there was, there'd be hundreds, if not thousands, of us standing in line and all the celiac organizations would be shouting it from the rooftops. We need to remain gluten-free for life. Plain coffee is gluten-free unless flavorings have been added to it that are not and I've never heard of coffee having a protein in it similar to gluten. Perhaps you could provide a link to substantiate your point. That said, a number of celiacs do have a problem with coffee for one reason or another and choose not to drink it.
