Gluten sensitivity: Can we use a program like this for desensitizing to food allergies and to desensitize to gluten? Maybe a grain or two of flour in water to start and very slowly work up?

My advice is to avoid gluten vs. trying to desensitize yourself to it, because of what we've done to it. Studies point to every human not being able to thrive with our modern day gluten and with it evoking some kind of low level immune response. The European double zero wheat is a different story and the body might be able to handle that at some point with your proposed plan.
