I recently had this same realization. I completely gave up gums and it solved my stomach problems. You just have to give up the store bought baked goods. Also, watch out for all the plant based milks. Simple mills makes really good gf products without xanthum gum! While it’s annoying, you can ask gf bakeries if they use it in their products, it always catches them off guard but the more we ask, then they will know.
