No, but there is an overlap that a lot of (but not necessarily all) products with gluten also contain a high amount of FODMAPs. Therefore even people without gluten allergies or celiac disease will see their digestive problems improve through eating gluten free products because they are also usually low in FODMAPS.

Telling those people that gluten isn't the problem doesn't help them, because it doesn't change the fact that they can't eat pizza, bread or pasta.
