Clean Out Your Kitchen
To begin, throw out any gluten-containing foods that have already been opened or have expired, or store them in a separate part of the pantry. Gluten-containing foods that haven't been touched can be given to a food bank or a homeless shelter.
Next, prepare a list of gluten-free replacements for some of the discarded things that you enjoy and use frequently. If you enjoy baking and have just gotten rid of your flour, for example, you should replace it with gluten-free flour such as rice flour or coconut flour. If you don't live with someone who isn't going gluten-free, set up a part of your pantry for gluten-free foods to minimize confusion.
