Gluten causes leaky gut syndrome, which makes people more susceptible to other problems. This inflammation happens regardless of whether you have celiac disease or not. Most people who have problems with gluten actually have IBS because of FODMAPs but low FODMAP food is a niche product. You can make low FODMAP bread with wheat without changing ingredients just by letting the dough sit longer but that cuts into profit margins so it won't be done.
