One of the difficulties in thinking about "gluten sensitivity" and food sensitivities in general, is that it glosses over the complexity of the situation. For example, when you eat a food, it may interact with your gut biome. In fact, it can change the composition and activity of the bacteria in your gut. For some diseases, it is becoming increasingly clear that the primary cause of the problem is not the food, but how the gut biome reacts to the food. If your body is unable to properly absorb the food, gut bacteria may have an over-abundance of nutrients, causing them to grow too much and release toxins in the body, damaging your ability to absorb food, while also potentially poising you in the process. This has been implicated in diseases as far ranging as ulcerative colitis, Crohn's, autism, and Celiac disease. Scientists are finally beginning to catch on to the complexity of the situation. I have Crohn's disease, and am just now starting the Specific Carbohydate diet. The basic idea of the diet is that it starves the bacteria, by limiting foods that reach the final phase of the digestion process, where the problematic bacteria exist. There have been two new studies released this year with positive results. Sadly, its difficult to get funding for this kind of research; the monetary incentives are not there the way they are for drug companies.
