Because wheat contains both gluten and fructans, it is easy to confuse the two. When you stop eating bread, you eliminate both. You feel better. You blame the gluten. But you may have simply lowered your FODMAP load.

When you mix flour and water and let it sit, a war for resources begins. The bacteria hunt for fuel. If given enough time, they will consume the fructans, effectively "pre-digesting" the bread before it ever reaches your plate.
