No, but if u have an allergic reaction to Gluten, I would test it first for safety. Although this is not instant coffee, the manufacturing process might make it cross-react with gluten, meaning u get an allergic reaction because of the way it was made, makes your body thinks u ate gluten. I'd speak with your doctor about it. If this is a life choice, u can't get fat from coffee, unless u add gluten to it.
