Amy, I would encourage you to ask his doctor but a few low FODMAP foods with gluten would be 100 % spelt bread (whole foods has a brand, French meadows), soy sauce, seitan (gluten rich vegan protein source), small amounts of wheat pretzels might be okay too — try 1/4
cup regular pretzels as a snack (Monash
allows these on their app), you might also try sourdough white bread (many of my clients can tolerate it when we do a wheat challenge) or Bay's English
muffins which are a white wheat based English
muffins, in the refrigerator section of the grocery store that many of my clients can tolerate too when we do the wheat challenge.
